SK hynix Gold P31 M.2 NVMe SSD Review in 1TB and 500GB


ATTO & CrystalDiskMark

ATTO v4.01.0f1

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB.

ATTO Disk Benchmark:

Benchmark Results: On ATTO Disk Benchmark found that both SK hynix 1TB NVMe SSD 3.06 GB/s write and right around 3 GB/s read at the standard queue depth of 4.

This again puts the SK hynix Gold P31 drives near the top of the performance charts as they manage to be super competitive with the other leading drives on the market today.

CrystalDiskMark 7.0.0 x64

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) and shows the highest score of five runs.


Peak Performance Preset

Real Performance Preset

Benchmark Results: The Gold P31 1TB drive came in with scores of 3598 MB/s read and 3223 MB/s write on CrystalDiskMark 7. The smaller P31 500GB model was able to best that with speeds of 3604 MB/s read and 3285 MB/s write! The 1TB model is rated at 3500 MB/s read and 3200 MB/s write and the 500GB model is 3500 MB/s read and 3100 MB/s write, so we were able to surpass the drives rated speeds. Random 4K performance was also excellent with ~77 MB/s read and ~195 MB/s write on both drives at a queue depth of 1. It doesn’t get much higher than that!
