AData S510 SATA 3 120GB SSD Review

PERFORMANCE BENCHMARKS

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Our testing provided results of 545MB/s read and 513MB/s write which is very close to AData’s listed specifications.

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/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who cant wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers.  We have provided compressible (oFill) results and chosen to follow up with AS SSD for incompressible benchmarks.

As we normally see, Crystal provides great high sequential results but falls short of the ATTO scores.  The low 4k random disk access speed of 86MB/s is an excellent score.

AS SSD BENCHMARK VER 1.64

Up until recently, ATTO was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the worst case scenario in SSD transfer speeds while using SandForce Driven SSDs as they use compression in storage as discussed earlier.  Many enthusiasts like to AS SSD for their needs.

The AS SSD results are the best example of testing with incompressible data and, once again, match that of listed specifications almost to a tee.
