ADATA XPG SX300 256GB mSATA SSD Review

AS SSD BENCHMARK VER 1.6

Up until recently, AS SSD 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 because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

We had expected to see better benchmark results in both transfer speeds and IOPS performance, although the results are very good.  Test results such as this are specifically why we run a variation of different benchmarks, many conducting the same testing.

On the other hand, the AS SSD Copy Bench result is amongst the best we have seen and some very quick transfer speeds were achieved through the three file transfers.

ANVIL STORAGE UTILITIES PROFESSIONAL (BETA)

You may not see this for long (and its definitely not common) but you get a freebee simply for reading!  Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.

COMPRESSIBLE (FILL)

INCOMPRESSIBLE (RANDOM)

Providing both Anvil Storage Utility results gives us a birds eye view on how performance fluctuates when testing with highly compressible data vs incompressible data.  As we can see, response times slows a bit as does the total IOPS and write performance at high sequential levels when testing with incompressible data.

Understanding that our system starts and runs programs with highly compressible data enables us to understand why compressible data speeds are so important.  Conversely, many enthusiasts prefer incompressible testing as it is representative of transferring highly incompressible files as we might see in movies, photographs and music.
