Plextor M6M 256GB mSATA SSD Review


ATTO & AS-SSD Benchmarks

ATTO v2.47

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 8192KB transfer sizes with the total length being 256MB.

ATTO – Intel Z77 Platform:

Benchmark Results: The writes on the Plextor M6M are weaker than all but a handful of drives in our comparison and the reads came in a the bottom of the pack. This rarely translates directly to real world performance but rather is one indicator of best case scenario performance.


AS-SSD (1.6.4237.30508) Benchmark – Intel Z77 Platform:

We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from two of them.

Benchmark Results: We see a different story here with the AS-SSD benchmark which uses incompressible data in its test set. The M6M grabbed the top spot in every category except sequential reads which really isn’t surprising since reads are usually roughly the same as on ATTO and we saw what happened there. Interestingly, the drive that did post the best overall sequential read scores as the previous generation M5M drive. In overall score, it blew the others away but bear in mind that this is a higher capacity drive than most we have reviewed which has an impact on performance.

Benchmark Results: As expected, the compressibility of data has no impact on the performance of the drive.
