Toshiba / KIOXIA XG5-P 2TB NVMe SSD Review

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 the KIOXIA XG5-P 2TB NVMe SSD peaked at 2.72 GB/s read and 991.77 MB/s write at the standard queue depth of 4. 

When we chart the 128KB test results from ATTO Disk Benchmark, the write speed of the KIOXIA XG5-P really hurt standings as it had the lowest write speed of any NVMe SSD. This put it near the bottom of the performance chart above the only SATA III SSD in the results.

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.

CystalDiskMark:

Benchmark Results: The Kingston KC2500 1TB drive came in with scores of 2914 MB/s read and 1051 MB/s write on CrystalDiskMark 7. This drive is rated as being up to 3000 MB/s read and 2200 MB/s write, so we are just below that on read and less than half of where we expected to be for writes.

Let’s look at some other benchmarks!
