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 WD Black PCIe 512GB SSD topping out at 2,204 MB/s read and 1,167 MB/s write in the standard overlapped I/O benchmark. This drive is rated at 2,500 MB/s max sequential read and 1,100 MB/s max sequential write, so we came up short on the read score.
Benchmark Results: When comparing the the other SSD models you can quickly see that it performs right in the middle of the pack of 12 drives that it is being compared against.
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.
Benchmark Results: The ADATA SX8000 PCIe NVMe 512GB SSD reached 1,414MB/s read and 1,080 MB/s write in the standard sequential write test and Random 4K performance was 44 MB/s read and 190 MB/s write. The Q32T1 performance was at 2565 MB/s read and 1159MB/s write, which is close to the drives rated sequential values of 2,500 MB/s read and 1,100 MB/s write. When we ran the test again set to 0Fill mode the sequential scores didn’t change much.
