WD_Black 4TB P50 SSD Reviewed – WD Intros 4TB Capacity of P50, Extreme and My Passport SSDs

CRYSTAL DISK INFO VER. 8.8.9

Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

Taking a look at Crystal Disk Info, we can validate that the SSD inside is the SN730E, this SSD is NVMe and using the NVMe 1.3 protocol.

INTEL vs AMD CPU SSD PERFORMANCE

In our testing today, we are using our X571 test bench with the Orico PCIe USB 3.2 Gen 2 20Gbps card installed.  When we tested the 2TB version of the P50, we had used our Intel Z270 Test bench.  There is a difference and we elected to test with the AMD bench today as it has become so popular with PC users, gamers, enthusiasts and professionals alike.   Although Intel SSD performance is bang on at 2GB/s read and 2GB/s right, AMD is a tad lower as we will see in today’s testing… tests results of the P50 on an Intel bench can be seen in this report.

ATTO DISK BENCHMARK VER. 3.05

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Listed specs for the 4TB P50 remain at 2GB/s read and write, but as we can see, AMD CPU performance is a bit lower at 1.71GB/s read and 1.62GB/s write.

CRYSTAL DISK BENCHMARK VER. 7.0.0 x64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
