Let's understand USB Type-C cables. It's just a dump


Xiaomi has introduced USB Type-C headphones in the Indian market with noise-canceling function and the highest sound quality. What's so interesting about them? Let's take a closer look.

These wired in-ear headphones were specially launched keeping in mind the Mi Mix 2 because the smartphone has a USB Type-C port instead of a 3.5mm audio jack.

According to analytical data, 32% of Xiaomi mobile phone users prefer headphones with a USB Type-C connector.

The headset body is made of titanium, which guarantees resistance to scratches and corrosion. The reproduced frequency range is 20-40,000 Hz with a sensitivity of 113 dB. Thanks to the Active Noise Cancellation (ANC) feature, the headphones are able to cancel out external noise.

The headphones are compatible with most Xiaomi smartphones that have a USB Type-C port:

  • Mi Mix 2,
  • Mi Mix,
  • Mi 6,
  • Mi 5,
  • Mi 5s,
  • Mi 5s Plus
  • Mi Note 2.

However, they are not compatible with Redmi 5X and Redmi Pro.

The headphones have a micromechanical noise reduction module that easily blocks out ambient noise. When the mode is turned on, noise is suppressed with a power of 25 dB, with a frequency range from 50 to 2000 Hz.

The Mi Noise Canceling USB Type-C wired headset is also not compatible with Redmi 4C and Redmi 4S. You can listen to music and the active noise cancellation function will work. But, you won't be able to take calls or control music using the built-in remote control.

The headphone cable is made of environmentally friendly material that is completely non-toxic. In addition, to achieve the best sound, the headphones have a digital decoder installed.

The accessory costs about $45. Overall, not bad at all for the price. Good build quality, active noise reduction, remote control and hardware audio decoding function to improve its sound.

USB Type-C is not only an improvement to the charging port of the device, but also an excellent opportunity to replace the 3.5 mm jack.

What is USB Type-C? What format is this? Now we will understand this using the example of the universal device Promate Unihub-C.

First, a little theory. Today, this format is an actively promoted connector on the market for connecting to peripherals and recharging devices.

These can be not only smartphones, but also some laptop models. The main difference from other formats is balanced plug. It is universal and works regardless of the connection side.

Development and certification were carried out by the USB Implementers Forum group of companies.

This group includes the largest electronics manufacturers such as Microsoft, Dell, HP, Intel and Samsung.

Many manufacturers supported the innovation, and are already actively are starting to implement it in their new developments.

USB Type-C is the latest, but has already joined the ranks of standard formats and is becoming increasingly relevant.

From the point of view of physical appearance, such a connector differs from the standard designs of the MicroUSB and MiniUSB formats, as more technologically advanced modifications.

The new format specification is based on 24-pin USB device connectors.

We list the new characteristics of the modified format:

  • number of signal pins – 24;
  • USB format supported – USB 3.1;
  • the implementation mode of third-party interfaces is now supported alternatively;
  • the data transfer rate has been increased to a maximum of 10 Gbit/s;
  • input current consumption is also increased, the maximum volume is 100 W;
  • standard dimensions – 8.34x2.56 mm.

Before the creation of USB 3.1, which supports USB Type-C, earlier versions were used. It all started with USB 1.0, but it did not enter the device market due to inferior development.

It has been replaced by a newer and more current version - USB 1.1. She became the first standard version, which all users quickly got used to.

The data transfer speed was only 12 Mbit/s, and the maximum current consumption was 100 mA.

After it they created the USB 2.0 version. It was presented at the beginning of the first quarter of 2000. There were main parameters increased.

Thus, the transmission speed increased to 480 Mbit/s. The maximum current consumption has also been increased - 1.8A to 2.5V.

USB 3.0 was introduced to the public at the end of 2008 and immediately won the trust of users, as it brought much more improvements than expected.

To distinguish it visually from other versions, it was made blue. Data transfer speed has increased significantly e – as much as 5 Gbit/sec, but the current consumption did not increase much – 5V by 1.8A.

The newest version is USB 3.1. It was developed and released to the device markets in 2013. She received the most maximum improvements to date.

The updated version featured the highest data transfer speed - up to 10 Gbit/s, and energy consumption increased to 100V.

Types of connectors

It is unlikely that many users remember such a connector as USB Type-A. Nevertheless, this connector is still used in PCs.

At the beginning of its existence, this connector was very popular, and the appearance of USB was almost no different from modern plugs.

The USB Type-B Mini connector was more popular. More often, it is used in modern mobile devices, cameras and other devices.

With its help, devices can be easily connected to a PC for data transfer. However, only the physical form was changed, and the standard remained the same - USB 2.0.

In order to somehow make the dimensions of smartphones and other mobile devices minimal, the format was optimized to Type-B Micro.

This connector format is used in 99% of smartphones and tablets based on . Even the very first smartphones have this connector.

The next step was to optimize USB to version 3.0, which, as we already said, introduced significant improvements to speed things up.

Devices using USB Type-C

Devices supporting this format are appearing in large numbers.

In the future, it is planned to transfer all Android devices to this format. This will speed up the charging process of the device and the speed of data transfer between the device and PC.

Google has announced that their branded devices will already have connectors of this format.

Thus, it turns out that the devices of this company will no longer be so easy to charge or connect to a PC, because the Type-C format has not yet been fully formed on the market.

You can only purchase a USB adapter cable complete with the device itself, since finding it separately is not yet so easy.

Not all stores, which are most often within walking distance from us, are able to purchase such peripherals for sale.

It all follows from this that peripheral wires with a Type-C connector will be available for now only in specialized stores, and only if they are available.

However, there are companies that are already launched the production of USB hubs with Type-C support. For example, the Promate device is uniHub-C.

This device has several outputs at once - USB 3.1 Type-C with a charging port, two USB 3.0 ports and a 4K HDMI port.

Key Features

  • Allows you to charge your MacBook and at the same time be connected to USB 3.0 and HDMI devices
  • The HDMI adapter allows you to connect a computer or laptop via USB 3.0 to a TV or any device that supports 4K resolution.
  • USB 3.0 connection from either side.
  • The hub is capable of working with the latest generation of computers and smart devices that support USB Type-C ports.
  • USB voltage - 5V, 900mA, data transfer speed - 5Gbps, support Windows 10/8/7 / Vista / XP, Mac OS X 10.2 (and higher)

The era of inconvenient connectors has come to an end. Some users no longer recognize the old 30-pin Apple cable, and microUSB is rarely seen even in budget phones. USB Type-C has become the standard in 2016, which is used in most announced devices. Even Apple decided, following the Macbook 2015, to deprive the new Pro line models of a regular USB connector. Does this mean the company will abandon Lightning soon?

Just a few years ago, the then new Lightning connector was perceived as an “amazing” replacement for the old and inconvenient analogue. No more hassle with getting into the charging port, and the smaller size of the new product contributed to the “weight loss” of the new iPhone models.

But time passes, the industry does not stand still, and the once revolutionary connector has become commonplace. And the outdated microUSB was replaced with a competitive Type-C, which in terms of capabilities could compete with Lightning.

The gradual transition to the new standard was very “painful”. Apple users were more comfortable with changing connectors, because they were accustomed to fairly high prices for cables, unlike owners of Android devices who were not willing to pay $10-20 for a piece of wire.

But it wasn't just the price that was the problem. The first devices with USB Type-C did not offer anything new, causing only inconvenience. After all, they did not use high-speed USB 3.1, but regular USB 2.0. This slowed the spread of the connector a bit. But now phones and laptops are appearing that take full advantage of all available potential.

One of the main advantages of USB Type-C is the ability to simultaneously charge and exchange large amounts of data. Using the new connector, a voltage of up to 100 W can be transmitted, which is about 20 V and 5 A. These values ​​are sufficient to charge almost any device, be it a tablet or a laptop. So there is a foundation for the future.

There’s no point in talking about ease of use here; symmetry eliminated the need to constantly check which side is connecting. But here it is worth noting that Lightning will be slightly better in terms of design reliability. After all, inside the USB connector, as before, there is a thin contact tab that can easily be broken if foreign particles enter. In this case, the owner will have to repair the USB input. But if Lightning breaks down, even if the plug is broken off, you will only need to change the cable.

Another drawback was the presence of a large number of cheap Chinese USB Type-C cables and the problem of controlling their quality. Such a wire, purchased for $1, could damage the battery or even cause the device to catch fire. The problem lies in the voltage passing through the cable, because in Chinese versions there was often no limitation, which was the reason for the breakdown of many phones.

But the fate of Lightning no longer seems so rosy. Devices using it still do not receive support for fast charging, the data transfer speed is inferior to its competitor, and the versatility of such a connector remains in question. Even Apple computers don't have it. To connect your phone to a new Macbook, you need to purchase additional adapters.

Cupertino has invested a lot of money in the development of Lightning, and it itself brings in good income from licensing, but it seems its time is running out. Switching to USB Type-C will allow you to charge all devices in the house with just one wire.

But don't expect Lightning to die anytime soon. There are a huge number of accessories available for it, and the recent removal of the 3.5mm miniJack has extended its life by several years. After all, the release of headphones using Lightning will bring considerable profit to Apple. And perhaps it will improve the characteristics of the connector to match them with its competitor.

Now USB Type-C is endowed with greater capabilities and looks more promising. So at the moment, it is he who wins the fight for the title of “most technologically advanced connector of 2016”.

The first version of the Universal Serial Bus (USB) was introduced in 1995. It was USB that became the most successful interface in the history of computing systems. Tens of billions of devices communicate with each other via USB, so the importance of this data transfer channel is difficult to overestimate. It seems that with the advent of the connector USB Type-C, our understanding of the capabilities and role of a universal bus may change dramatically. Before talking about the prospects, let's look at what the new universal connector offers.

The advantages and disadvantages of the new format interface connector have been discussed on the Internet for some time. The USB Type-C specification was finally approved at the end of last summer, but the topic of a universal connector aroused active interest after the recent announcement of a laptop, as well as a new version equipped with USB Type-C.

The USB Type-C connector is slightly larger than the usual USB 2.0 Micro-B, but noticeably more compact than the dual USB 3.0 Micro-B, not to mention the classic USB Type-A.


The dimensions of the connector (8.34x2.56 mm) allow it to be used without any particular difficulties for devices of any class, including smartphones/tablets with a minimum reasonable case thickness.

Structurally, the connector has an oval shape. Signal and power terminals are located on a plastic stand in the central part. The USB Type-C contact group includes 24 pins. This is much more than the previous generation of USB connectors. Only 4 pins were allocated for the needs of USB 1.0/2.0, while USB 3.0 connectors have 9 pins.

The first obvious benefit of USB Type-C is the symmetrical connector, which allows you not to think about which side to connect the plug to the socket. The age-old problem of devices with USB connectors of any format has now finally been resolved. At the same time, the solution to the problem is achieved not by the banal duplication of all contact groups. A certain automatic negotiation and switching logic is used here.

Another nice thing is that there are identical connectors on both sides of the interface cable. Therefore, when using USB Type-C, you do not need to choose which side of the conductor to connect the master and slave devices.

The outer shell of the connector does not have any holes or cutouts. To secure it in the connector, internal side latches are used. The plug must be held securely enough in the connector. There should not be any backlashes similar to those that could be observed with USB 3.0 Micro-B.

Many people are probably concerned about the physical reliability of the new connector. According to the stated characteristics, the mechanical life of the USB Type-C connector is about 10,000 connections. Exactly the same indicator is typical for the USB 2.0 Micro-B port.

Separately, we note that USB Type-C is not a data transfer interface. This is a type of connector that allows you to tie together various signal and power lines. As you can see, the connector is elegant from an engineering point of view, and most importantly, it should be easy to use.

Data transfer rate. 10 Gb/s is not for everyone?

One of the advantages of USB Type-C is the ability to use the USB 3.1 interface for data transfer, which promises an increase in throughput up to 10 Gb/s. However, USB Type-C and USB 3.1 are not equivalent terms and are definitely not synonyms. The USB Type-C format can implement the capabilities of both USB 3.1 and USB 3.0 and even USB 2.0. Support for a particular specification is determined by the integrated controller. Of course, USB Type-C ports are more likely to appear on devices that support high data transfer rates, but this is not a dogma.

Let us remind you that even with the implementation of USB 3.1 capabilities, there may be differences in the maximum data transfer speed. For USB 3.1 Gen 1 it is 5 Gb/s, USB 3.1 Gen 2 is 10 Gb/s. By the way, the presented Apple Macbook and Chromebook Pixel have USB Type-C ports with a bandwidth of 5 Gb/s. Well, a clear example of the fact that the new interface connector is very variable is the Nokia N1 tablet. It is also equipped with a USB Type-C connector, but its capabilities are limited to USB 2.0 with a bandwidth of 480 Mb/s.

The designation “USB 3.1 Gen 1” can be called a kind of marketing ploy. Nominally, such a port has capabilities identical to those of USB 3.0. Moreover, for this version of “USB 3.1” the same controllers can be used as for the implementation of the previous generation bus. At the initial stage, this technique will probably be actively used by manufacturers, releasing new devices with USB Type-C that do not require maximum bandwidth. When offering a device with a new type of connector, many will want to present it in a favorable light, declaring the presence of not only a new connector, but also support for USB 3.1, even if only conditional.

It is important to understand that the USB Type-C port can nominally be used for maximum performance connectivity at speeds of up to 10 Gb/s, but in order to obtain such bandwidth, the connected devices must provide it. The presence of USB Type-C does not indicate the real speed capabilities of the port. They should be clarified in advance in the specifications of specific products.

Some restrictions also have cables for connecting devices. When using the USB 3.1 interface, for lossless data transfer at speeds up to 10 Gb/s (Gen 2), the length of the cable with USB Type-C connectors should not exceed 1 meter, for connection at speeds up to 5 Gb/s (Gen 1) – 2 meters.

Energy transfer. 100 W unit

Another important feature that USB Type-C brings is the ability to transmit power up to 100 W. This is enough not only to power/charge mobile devices, but also for the trouble-free operation of laptops, monitors or, for example, “large” external drives of 3.5” format.

When the USB bus was originally developed, power transfer was a secondary function. The USB 1.0 port provided only 0.75 W (0.15 A, 5 V). Enough for a mouse/keyboard to work, but nothing more. For USB 2.0, the nominal current was increased to 0.5 A, which made it possible to obtain 2.5 W. This was often enough to power, for example, external 2.5” hard drives. For USB 3.0, a nominal current of 0.9 A is provided, which, with a constant supply voltage of 5V, already guarantees a power of 4.5 W. Special reinforced connectors on motherboards or laptops were capable of delivering up to 1.5 A to speed up charging of connected mobile devices, but this is still 7.5 W. Against the background of these figures, the possibility of transmitting 100 W looks like something fantastic. However, in order for the USB Type-C port to be filled with the necessary power, support for the USB Power Delivery 2.0 (USB PD) specification is needed. If there is none, the USB Type-C port will normally be able to output 7.5 W (1.5 A, 5 V) or 15 W (3 A, 5 V) depending on the configuration.

To streamline the energy capabilities of USB PD ports, a system of power profiles was developed that provides possible combinations of voltages and currents. Compliance with Profile 1 guarantees the ability to transmit 10 W of energy, Profile 2 – 18 W, Profile 3 – 36 W, Profile 4 – 60 W, Profile 5 – 100 W. A port corresponding to a higher-level profile maintains all states of the previous ones downstream. 5V, 12V and 20V were selected as reference voltages. The use of 5V is necessary for compatibility with the huge fleet of available USB peripherals. 12V is the standard supply voltage for various system components. 20V was proposed taking into account the fact that external 19–20V power supplies are used to charge the batteries of most laptops.

Of course, it’s good when the device is equipped with USB Type-C, which supports the maximum USB PD energy profile. It is this connector that allows you to transmit up to 100 W of energy. Obviously, ports with similar potential may appear on some powerful laptops, special docking stations or motherboards, where separate phases of the internal power supply will be allocated for the needs of USB Type-C. The point is that the required power must be somehow generated and supplied to the USB Type-C contacts. And to transmit energy of such power, active cables will be required.

It is important to understand here that not every port of the new format will be able to provide the declared power of 100 W. There is a potential opportunity for this, but this issue must be resolved by the manufacturer at the circuit design level. Also, don’t be under any illusions that the above 100 W can be obtained from, say, a power supply the size of a matchbox, and now you can charge your gaming laptop and a 27-inch monitor connected to it using a smartphone charger. Still, the law of conservation of energy continues to work, and therefore a 100 W external power supply with a USB Type-C port will still be the same weighty block as before. In general, the very possibility of transmitting energy of such power using a universal compact connector is, of course, a plus. At a minimum, this is a great opportunity to get rid of the inconsistency of original power connectors, which laptop manufacturers especially often sin with.

Another useful feature of USB Type-C is the ability to change the direction of energy transfer. If the circuit design of the devices allows, the consumer can, for example, temporarily become a charge source. Moreover, for reverse energy exchange, you don’t even need to reconnect the connectors.

Alternative mode. Not USB alone

The USB Type-C port was originally designed as a universal solution. In addition to direct data transfer via USB, it can also be used in Alternate Mode to implement third-party interfaces. The VESA Association took advantage of this flexibility of USB Type-C by introducing the ability to transmit video streams via DisplayPort Alt Mode.

USB Type-C has four high-speed lines (pairs) of Super Speed ​​USB. If two of them are dedicated to DisplayPort needs, this is enough to get a picture with a resolution of 4 K (3840x2160). At the same time, the data transfer speed via USB does not suffer. At its peak it is still the same 10 Gb/s (for USB 3.1 Gen2). Also, the transmission of the video stream does not in any way affect the energy capacity of the port. Even 4 high-speed lines can be allocated for DisplayPort needs. In this case, modes up to 5K (5120×2880) will be available. In this mode, USB 2.0 lines remain unused, so USB Type-C will still be able to transfer data in parallel, although at a limited speed.

In alternative mode, the SBU1/SBU2 pins are used to transmit the audio stream, which are converted into AUX+/AUX- channels. For the USB protocol they are not used, so there are no additional functional losses here either.

When using the DisplayPort interface, the USB Type-C connector can still be connected to either side. The necessary signal coordination is provided initially.

Connecting devices using HDMI, DVI and even D-Sub (VGA) is also possible, but this will require separate adapters, but these must be active adapters, since DisplayPort Alt Mode does not support Dual-Mode Display Port (DP++) .

Alternative USB Type-C mode can be used not only for the DisplayPort protocol. Perhaps we will soon learn that this port has learned, for example, to transmit data using PCI Express or Ethernet.

Compatibility. Difficulties of the “transition” period

If we talk about the compatibility of USB Type-C with devices equipped with USB ports of the previous generation, then it is not possible to connect them directly due to fundamental differences in the design of the connectors. To do this you will need to use adapters. Their range promises to be very wide. Of course, we are not just talking about converting USB Type-C to other USB types. Adapters for displaying images on screens with traditional DisplayPort, HDMI, DVI and VGA ports will also be available.

Along with the announcement of the new MacBook, Apple offered several adapter options. Single USB Type-C to USB Type-A is priced at $19.

Considering the presence of only one USB Type-C, the owner of a MacBook probably cannot do without a universal, more functional converter. Apple presented two such adapters. One output has USB Type-C, VGA and USB Type-A pass-through, the second option is equipped with HDMI instead of VGA. The cost of these boxes is $79. A 29 W power supply with native USB Type-C is priced at $49.


For the new Chromebook Pixel system, Google offers single adapters from USB Type-C to Type-A (plug/socket) priced at $13; for a converter to DisplayPort and HDMI you will have to pay $40. A 60 W power supply is priced at $60.

Traditionally, you should not expect humane price tags for additional accessories from equipment manufacturers. Adapter manufacturers are anticipating demand for their new products. Belkin is already ready to ship kilometers of conductors, but their cost also cannot be called low ($20–30). The company also announced, but has not yet introduced, an adapter from USB Type-C to a Gigabit Ethernet port. The price has not yet been announced; there is only information that it will be available in early summer. It's funny, but it seems that until this moment, in order to connect to a wired network, you will need to use two adapters at once. It is quite possible that someone will be more prompt than Belkin, offering an appropriate adapter earlier.

It will be possible to talk about a noticeable price reduction only after much lesser-known companies from the Middle Kingdom begin to work closely on accessories with USB Type-C. Considering the prospects that are opening up, we believe that this will not be the case.

Devices with USB Type-C. Someone has to be first

Nominally, the first device equipped with a USB Type-C port was a tablet. At least, it was this device that became the harbinger of the fact that ports of the new format left the developer’s laboratories and “went to the people.”

An interesting device, but, unfortunately, it is currently offered in a fairly limited edition. The tablet has a native USB Type-C port, although the USB 2.0 protocol is used for data transfer.

Perhaps the most significant product that will help increase the popularity of USB Type-C is the recently introduced . The 12-inch laptop is equipped with a single interface connector, so its owners will one way or another become pioneers who will adapt to life with USB Type-C.

On the one hand, Apple obviously supported the development of the new standard; moreover, the company’s engineers were directly involved in the development of USB Type-C. On the other hand, updated versions of Macbook Air and MacBook Pro did not receive this connector. Does this mean that the manufacturer’s USB Type-C will not be included in the “heavier” category of devices in the coming year? Debatable. After all, Apple probably won’t be able to resist updating its line of laptops after the autumn announcement of a new Intel mobile platform with Skylake processors. Perhaps this is when the Cupertino team will allocate space on the interface panel for USB Type-C.

The situation with tablets and smartphones is even more ambiguous. Will Apple use USB Type-C instead of Lightning for them? In terms of capabilities, the proprietary connector is noticeably inferior to the new universal port, but what about the original peripherals that users of Apple mobile products have accumulated since 2012? We will find out the answers to these questions with the update or expansion of the iPhone/iPad lines.

Google has introduced the second generation of stylish Chromebook Pixel laptops. Systems running Chrome OS are still fairly niche solutions, but the quality of Google’s systems is captivating, and this time they are at the forefront of devices offering USB Type-C connectivity. Laptops are equipped with a pair of corresponding connectors. However, to be on the safe side, Chromebook Pixels also have two classic USB 3.0 connectors.

In general, Google representatives are very encouraged by the capabilities of the new connector, counting on the appearance of Android mobile devices with a USB Type-C connector in the near future. Uncompromising support from the largest platform holder is a powerful argument for other market players.

Motherboard manufacturers are not yet in a particular hurry to add a USB Type-C port for their devices. MSI recently introduced the MSI Z97A GAMING 6, which is equipped with such a connector with data transfer speeds of up to 10 Gb/s.

ASUS offers an external USB 3.1 controller with a USB Type-C port, which can be installed on any board with a free PCI Express (x4) slot.

Peripherals with native USB Type-C are still frankly not enough. Surely many manufacturers were in no hurry with the announcement, waiting for the appearance of systems with which it would be possible to use products with USB Type-C. In general, this is a typical situation when introducing another industry standard.

Immediately after the announcement of the Apple MacBook, LaCie introduced a series of portable external hard drives with USB Type-C.


SanDisk is already offering a flash drive with two connectors for testing – USB 3.0 Type-A and USB Type-C. The lesser known Microdia offers a similar product.

Surely we will soon see a significant expansion of the range of devices with USB Type-C. The flywheel of change will slowly but surely spin up. The support of “big” companies can influence the situation and speed up this process.

Results

The need for a universal compact connector that could be used to transmit data, video-audio streams and electricity has been brewing for quite some time. Considering the mutual interest on the part of both users and equipment manufacturers, there are all the prerequisites for USB Type-C to take off.

Compact dimensions, simplicity and ease of connection, along with ample capabilities, promise the connector the prospect of repeating the success of its predecessor. The usual USB port has been modernized several times, but the time has come for drastic changes. 10 Gb/s with the possibility of further scaling, power transmission up to 100 W and a picture with a resolution of up to 5K. Not a bad start? Another argument in favor of USB Type-C is that it is an open standard that does not require licensing fees from manufacturers. There is still a lot of work ahead, but there is a result ahead that is worth going through this path for.

Flash cards (or so-called flash drives) will not surprise anyone these days. They have come a long way to the mini-sized devices that many of you probably have. The only thing that can move this market segment forward is the development and support of new standards. Therefore, as soon as we had one of the first flash drives and the USB 3.1 standard, we decided to immediately tell you about it.

It is immediately clear from the box that we are dealing with something tiny - the length of the flash card does not exceed one inch. Actually, there is nothing in the box except the flash drive itself: and it would be strange to expect anything else here.


On one side there is the USB Type-A (3.1) standard, familiar to many users, and on the other there is the same 3.1, only with a USB Type-C connector, protected by a special cover.


Just look how miniature it is - for example, in comparison with the same, the dimensions of which are well known to everyone.



To insert a flash drive into a new MacBook (and this is now from Apple), just move the cover and then start copying all the necessary data. Even in comparison with such a baby as a MacBook, the flash card looks very small. Such that it is almost unnoticeable.



This accessory will become indispensable for you if you have both a new MacBook and a laptop without USB Type-C support. With its help, transferring data from one device to another will become not only very simple, but also fast - we were able to verify this ourselves.



Information obtained using the BlackMagic Disk Speed ​​Test program suggests that transfer speeds over USB 3.1 (Type-A) and Type-C are almost the same. It would be strange to see something different - after all, Type-C is essentially a pleasant “bonus” to the usual USB 3.1.
