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 US900 SSD topping out at 564 MB/s read and 523 MB/s write in the standard overlapped I/O benchmark. This drive is rated at up to 560 MB/s max sequential read and 520 MB/s max sequential write, so we exceeded both of those scores on our test platform.
Benchmark Results: When comparing the ADATA SU900 SSD to some other SSDs that we selected to compare it against you can see that it pretty much mirrors the performance of the WD Blue SATA SSD with regards to sequential write performance.
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 SU900 Ultimate 512GB SSD reached 532MB/s read and 490 MB/s write in the standard sequential write test and Random 4K performance was 30 MB/s read and 114 MB/s write. The Sequential Q32T1 performance was at 564 MB/s read and 519 MB/s write, which is close to the drives rated sequential values of 550 MB/s read and 505 MB/s write on CrystalDiskMark. When we ran the test again set to 0Fill mode the sequential read scores mostly improved while all the write scores dropped just slightly.
Let’s look at some other benchmarks!
