WD offered one of the first peripherals for USB 3.2 Gen 2x2. The transfer rate of 20 Gbps for most users is still only a technical parameter in the drive specifications, because motherboards with this interface are currently scarce on the market. It is a Game drive, so WD is aimed primarily at players and technology geeks.
WD launched the WD_Black P50 SSD, which was introduced earlier this year. The drives are truly threaded, inside with a warm internal NVMe SSD with a maximum transfer rate of 20 Gbps, 500 GB, 1 TB and 2 TB capacities and connection via USB-C cable will expand the capacity of (especially) the notebooks or game consoles of many a stick freak or technology geek.
But there is a catch: your computer or game console probably does not have a USB 3.2 Gen 2x2 interface, it is only a few weeks ago (on November 27, 2019 exactly) that Gigabyte introduced the first PCIe card that can offer your computer the necessary interface.

With these parameters, the WD_Black P50 ranks among the top of the line of the fastest external drives available for purchase using the USB 3.2 gen 2x2. The question remains when this new USB interface will become a common part of our computers, game consoles and mobile devices.
Don't have a USB 3.2 Gen 2x2 ? Of course the WD_Black P50 SSD can also be connected to older USB versions.
If you are not among those whose computer or game console already has the latest version of USB, then of course you can connect WD_Black P50 to the older version of USB. You will find the USB-C and USB-A connection cables in the package.
Do you get lost in USB interface and cable designations? And what about those baud rates?
No wonder USB markings have been slightly confused lately. Let's see how things are with them:
- USB 3.2 Gen 2x2 - the so-called SuperSpeed USB, which offers a transfer rate of up to 20 Gbps.
- USB 3.2 Gen 2 - an older version of SuperSpeed USB, which has "only" a speed of 10 Gbps. To be a little confused, this interface was formerly called USB 3.1 Gen 2 and USB 3.1 respectively.
- USB 3.2 Gen 1 - offers a maximum transfer rate of 5 Gbps and was formerly known as USB 3.1 Gen 1 and USB 3.0 respectively.
- USB 2.0 - just for the sake of comparison, this outdated interface has a maximum transfer rate of 480 Mbps, roughly 1/40 of today's fastest USB speed.
- USB cable type C - the latest USB connector, which can be found on modern external drives, mobile phones, etc. The cable can be connected in either way, no need to monitor the connection method.
- USB cable type A - an older type of USB cable that you connect to most current computers and game consoles. This cable or connector can only be connected in one way.
USB 3.2 Gen 2x2 vs SATA III vs NVMe
Some other manufacturers are also currently marketing external USB drives with USB 3.2 Gen 2x2, which in itself can only be a marketing figure, because the drive itself is far from being able to use it. This is due to the NAND memory technology used and other parameters. For the sake of clarity, here is a comparison of the transfer rates of individual interfaces.
- NVMe - The latest interface for modern SSD drives. It offers a transfer rate of up to 32 Gbps. NVMe is a protocol developed specifically for PCIe SSDs. It is also used, for example, inside the WD_Black P50.
- USB 3.2 Gen 2x2 - Maximum transfer rate 20 Gbps.
- SATA III - Currently a widely used interface for hard drives, both SSD and classic HDD. It achieves a maximum transfer rate of 6 Gbps.
- SATA II - Maximum transfer rate 3 Gbps.
Although SATA III has a maximum transmission rate of 6 Gbps, which means approx. up to 600 MB for both write and read, hard disk drives (HDDs) did not reach this speed. Their real-time reading and writing technologies reached speeds of up to about 150 MB for reading and 130 MB for writing.
Data Recovery from SSD and WD_Black P50
Given the focus of this drive, it can be assumed that its owners will not need much data recovery from SSD. However, this is an interesting technological innovation, so we have included it in our blog.
