WD Black P50: 20-gigabit USB 3.2 gen 2×2 in action

Overview

I first saw this novelty called P50 Game Drive last September during our visit to Berlin at IFA 2019. In addition to its non-traditional design, this external SSD is particularly interesting for its unique connection. This is one of the first storage disks to use the fastest form of the USB protocol labelled as 3.2 gen 2×2 , which offers speeds of up to 20 Gbps. Until the arrival of the 4.0 standard, this is the fastest universally available USB.

P50 Game Drive SSD

So far, perhaps the most interesting package of an external SSD has an interesting dotted pattern, a glossy black name and also a representation of the SSD itself. There are also basic specifications such as speed, warranty, etc.

In the package you will find the SSD itself, a pair of cables with USB-C and USB-A and short documentation. The SSD uses a USB 3.2 gen 2×2 with a throughput of 20 Gbps for transfers. However, it is not the fastest port, that is still Thunderbolt 3 or the newly introduced Thunderbolt 4 (both 40 Gbps). The new USB 4.0 will offer the same 40 Gb speed, but until then, 20 Gbps is the fastest universal connection. Unlike Thunderbolt drives, it is compatible with all versions of USB and you can use it not only on Windows and macOS, but also on Playstation or Xbox and mobile devices.

The design of the SSD is clearly different from the other models we’ve had here. The P50 has a hardened aluminum body with a robust design that resembles durable drives, so it’s no ssuurprise that the manufacturer states increased impact resistance. Unfortunately, water resistance as in the case of SanDisk Portable SSD is no longer mentioned.

The metal body has rubber feet on the bottom so that it does not slip on the table. Apart from the USB-C port and the white LED indicator, there are no other elements on it. The already mentioned ribbed outer cover is unconventional. A disadvantage of the black design will certainly be its proneness to fingerprints, dust, but also scratches.

A comparison with other already tested external SSDs shows us that the P50 is the largest and most robust of them. The weight of 112 grams proves it. For comparison, most SSDs are in the range of about 40–50 grams. Thus, the P50 will be more suitable for home use than for everyday carrying in a pocket or the like.

Like the My Passport SSD, the P50 handled our 300 GB continuous write test with a stable speed of around 680 MB/s without any problems. This is due to the SanDisk BiCS 3 64L 3D TLC NAND memory.

Testing took place on the Z490 platform, specifically on the MSI MEG Z490 Ace motherboard with Intel Core i9-10900K and 32 GB 3600 MHz DDR4 Corsair Dominator Platinum, from which 25 GB was allocated for RAM disk.

Rare host: How does an SSD work in the Asus Dual RTX 4060 Ti?

Among RTX 4060 Ti graphics cards, Asus has multi-functional designs with an M.2 slot for NVMe SSDs. These, unlike other models, don’t waste the potential of the PCI Express ×16 interface so significantly. To evaluate this design, partial results from motherboard tests are now extremely useful. Those results that relate to the M.2 slot speeds and the efficiency of SSD coolers. After all, the Asus Dual RTX 4060 Ti SSD also competes in both disciplines.

GeForce RTX 4060 Ti with M.2 slot launched, can use PCIe 5.0 SSD

Some GPUs in current gaming graphics cards use just eight PCIe lanes instead of the whole ×16 interface. This includes cards like the Radeon RX 7600 and also the GeForce RTX 4060 and 4060 Ti. Asus recently came up with an idea to make use of the extra lanes that would go to waste such a GPU, and made a graphics card that gets some utility out of of the excess lanes, using them to connect an SSD and provide an extra M.2 slot.

Asus puts M.2 SSD on GeForce RTX 4060 Ti to make use of PCIe ×16

There’s more and more graphics cards that don’t use the full width of PCI Express ×16 slot and run with just eight lanes to cut GPU die area and cost. This usually renders the remaining eight lanes useless, but Asus has now come up with an idea to make them useful. They still won’t be usable for the graphics card itself, but at least they’ll find some use. It could come in handy on A620 boards with a shortage of M.2 slots, for example.
