Performance
Performance has been measured using our usual set of benchmarks like ATTO, CrystalDiskMark, AS SSD and Anvil’s Storage Utilities. Test platform is based on Core i5 4670K CPU and ASRock Z87M OC Formula. ADATA SSD has been connected to Intel SATA6G ports.
ATTO Disk Benchmark
As we see on the attached screenshot from ATTO Benchmark, ADATA SP920 256GB is performing slightly better than it was specified by manufacturer. Write bandwidth is reaching declared 360MB/s while read is up to 6GB/s higher so we could see 566MB/s mark after couple of benchmark runs. It’s one of the highest sequential read result that I saw on the single SSD and it’s about maximum for SATAIII controllers.
CrystalDiskMark 3.0.3 x64
CrystalDiskMark is performing additionaly random read and write tests. Also here we can see exceptional performance of ADATA SP920 SSD. Especially 4K read test is really good with result above 33MB/s. Most available SSD, even these from high end series, are giving up at about 25-27MB/s.
Maximum bandwidth results are usually lower in CrystalDiskMark than other tests and it’s normal as results depend from used test files.
AS SSD Benchmark
AS SSD is similar to CDM and it’s pretty stressful benchmark for most drives. Results are also lower than we can see in ATTO but as I already mentioned, it depends from used test files. Overall results in this benchmarks are really good. Every test is presenting high bandwidth and final score is also high – 1108. This is one of the highest results achieved on high end SSD available at the moment.
Anvil’s Storage Benchmark
Anvil’s Storage benchmarks are once again showing us sequential and random bandwidth results on a different test files. We can see similar results to CDM or AS SSD benchmarks what is actually really good.
Anvil’s tests are also including IOPS measure. Write IOPS are above declared by ADATA passing 81k while read is lower, nearly 71k. Once again all depends from test files and other variables but overall result still looks good.
