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.
Benchmark Results: ATTO showed the ADATA SU800 Ultimate 512GB SSD topped out at 564 MB/s read and 519MB/s write in the standard overlapped I/O benchmark. ADATA rates this particular model at up to 560 MB/s read and 520 MB/s write, so we are close to the rated speeds.
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.
Benchmark Results: The ADATA SU800 512GB drive reached 550 MB/s read and 509 MB/s write in the standard sequential write test. The Random 4K performance on the SU800 512GB drive was 37 MB/s read and 137 MB/s write. When we ran the test again set to 0Fill mode and all the scores remained basically the same as you can see above.
