WD Black P50 Game Drive SSD review: It's as fast as it looks

But to get maximum performance requires a SuperSpeed USB 20Gbps port.

Never has an external SSD appeared more ready for a virtual shoot-‘em-up than the WD Black P50 Game Drive NVMe SSD. Even better, if you happen to be one of the lucky few with a SuperSpeed USB 20Gbps (formerly known as USB 3.2 gen 2x2) port on your computer, it delivers nearly 2GBps transfers. Over older USB, it’s no faster than the less expensive competition. 

Design and features

The WD Black P50 Game Drive SSD looks the part for virtual combat, right down to the action-film computer font.

The P50’s design evokes an ammo box, or a shipping container from a sci-fi flick. The action-movie computer fonts used in the labeling on the enclosure heighten that impression. If you think I’m imagining the military bent of the design, check out the product buy page, where you’ll find phrases such as  “your secret weapon,” and “combat-tested.” 

As to the actual specs, the P50 measures 4.65 x 2.66 x 0.56 inches and weighs about 4 ounces. That’s a bit larger than most (you’re likely to notice it’s in your pocket), but it still sits nicely in your hand. 

Inside the unit is undoubtedly one of WD’s top-rated Black NVMe SSDs, though WD declined to specify which one. The P50 is available in three capacities: 500GB (currently $180 on Amazon), 1TB (the size we tested, currently $250 on Amazon), and 2TB (currently $450 on Amazon). The warranty lasts five years. Both Type-C and Type-A-to-Type-C cables are included in the box. 


The 1TB unit we tested finished in a statistical dead heat with the only other SuperSpeed USB 20Gbps drive we’ve tested—the Seagate FireCuda Gaming SSD.  The chart below shows both the 10Gbps and 20Gbps performance of the drives. Not surprisingly, there’s an almost two-fold increase in speed with SuperSpeed USB 20Gbps, thanks to an additional pair of data wires in use.

The difference between the FireCuda Gaming SSD and the P50 Black Game Drive SSD is minimal, the difference between 10Gbps and 20Gbps performance is huge.

In CrystalDiskMark at 10GBps, the P50 was noticeably slower writing than the FireCuda, but noticeably faster reading. Trade-off. The story was much the same versus the OWC Envoy EX USB-C and Sandisk Extreme Pro Portable 10Gbps-only drives, as shown below.

the P50 Black Game Drive SSD isn’t as fast a writer as the FireCuda Gaming SSD, but it’s a better writer. Niether drive is the champ when it comes to 10Gbps performance.

In our real-world 48GB transfer tests performed at 10Gbps, the story was essentially the same: The P50’s speedy reading compensated somewhat for its slightly slow writing. Unofficially (and not shown), on a sample 20Gbps testbed, both the WD and Seagate cut into these times drastically. Multiply by 0.6 for a rough estimate.

Among the four drives in the real-world 48GB copy test, we see some noticeable differences betweed read and write speeds. 

The transfer tests (10Gbps) ended too close to call with the various test results totaled; however, there were differences in the individual tests. The P50 is definitely a faster reader than most, but a slower writer. In the grand scheme of external storage, it’s quite adept at both. 

Testing is performed on Windows 10 64-bit running on a Core i7-5820K/Asus X99 Deluxe system with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (Nvidia) GT 710 1GB x2 PCIe graphics card, and an Asmedia ASM2142 USB 3.1 Gen 2 (SuperSpeed USB 10Gbps) card. Also on board are a Gigabyte GC-Alpine Thunderbolt 3 card and Softperfect’s Ramdisk 3.4.6, which is used for the 48GB read and write tests.

USB Gen 2x2/SuperSpeed USB 20Gbps was tested with the same components listed above, with the exception of a Threadripper 3970X on loan from AMD and an MSI Creator TRX4 motherboard.

Note that USB4 will support SuperSpeed USB 20Gbps and add SuperSpeed USB 40Gbps.

Great if you want the styling and have the gear

Do you need 2GBps transfers for gaming? Heck no. Would you like to have them? Heck yeah. Any time a drive makes you wait, it’s not fast enough. The WD Black P50 Game Drive SSD won’t make you wait a lot—it’s an excellent drive, and its styling may put gamers in the mood for digital mayhem.

The real issue is bang for the buck. If you have a SuperSpeed USB 20Gbps port, the P50 gives you extra speed for the extra cash. Nice. If you don’t yet have said port, you’re paying a hefty premium for appearances. Your choice.

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries


As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.
