WD Blue 1TB SSD Review


ATTO & CrystalDiskMark

ATTO v3.05

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 – WD Blue 1TB:

WD Blue 1TB SSD ATTO Benchmark

Benchmark Results: ATTO showed the WD Blue 1TB SSD topped out at 557 MB/s read and 536 MB/s write in the standard overlapped I/O benchmark. WD rates this particular model at up to 545 MB/s read and 525 MB/s write using CrystalDiskMark, so we are able to easily best that on this benchmark.

CrystalDiskMark 5.1.2 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) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.

CystalDiskmark – ADATA SU800 512GB:

WD Blue 1TB SSD CrystalDiskMark

Benchmark Results: The WD Blue 1TB drive reached 534 MB/s read and 504 MB/s write in the standard sequential write test. The Random 4K performance on the WD Blue 1TB drive was 41 MB/s read and 131 MB/s write. When we ran the test again set to 0Fill mode and all the scores remained basically the same, but the sequential performance did improve a bit more than we expected.

WD rates this particular model at up to 545 MB/s read and 525 MB/s write using CrystalDiskMark and we were unable to get sequential read/write speeds that high.

Let’s look at some other benchmarks!
