ADATA S511 120gb SATA 3 Review: Crystal Diskmark and AS SSD Benchmarks

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill) or random data. Many new SSD owners who can’t wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with random data, not RAW or ‘0Fill’ data as tested by manufacturers.  The ‘0Fill’ result is on the left and ‘random data’ result on the right.

We like to use Crystal, for the most part, as it gives a clear indication of the all important 4k random writes which fall right in line here.  We have to admit though that we started to wonder about the low high sequential and 512kb write transfer speeds as we like to see them typically about 100MB/s higher in both RAW and random data sampling.  If it is anything to be concerned about, confirmation will be shown with significantly low PCMark Vantage results in comparison testing.

AS SSD BENCHMARK VER 1.64

AS SSD Disk Benchmark is perhaps the only benchmark program that was created for solid state drives.  As AS SSD uses random data, we might see similar results to the Crystal score above and right.

Once again, the low write score of 161MB/s with random data concerned us just a bit.  Let’s see how reflective it is in the new AS SSD Copy Benchmark.

This score is typical of an upper tier ‘new generation’ SATA 3 drive and had a much better showing then the other 120GB SandForce controlled drive we have tested, the OWC Mercury Extreme Pro 6G 120GB SSD.  Here’s a look at AS SSDs new Compression Benchmark:

In comparison, the read results are right at par and the write, although starting a bit low, find their way up to where they typically are in similar SSD testing.
