Plextor M6S 256GB SSD Review

Anvil Storage Utilities


Version and / or Patch Used: RC6


So what is Anvil Storage Utilities? First of all, it's a storage benchmark for SSDs and HDDs where you can check and monitor your performance. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or the write test, or you can run a single test, i.e. 4k QD16.


Anvil Storage Utilities is not officially available yet, but we've been playing with the beta for several months now. The author, Anvil on several international forums, has been updating the software steadily and is adding new features every couple of months.


The software can be used several different ways to show different aspects for each drive. We've chosen to use this software to show the performance of a drive with two different data sets. The first is with compressible data, and the second data set is incompressible data. Several users have requested this data in our SSD reviews.



0-Fill Compressible Data




Incompressible Data




The Plextor M6S works with both compressible and incompressible data the same way, so performance stays the same regardless of data type.



Read IOPS through Queue Depth Scale




The low queue depth IOPS performance is very good. At QD1, we achieved just under 9400 IOPS. The M6S scales well, going from just over 17k IOPS at QD2 to tipping the scales at nearly 95k IOPS at QD32.


Scaling Write IOPS through Queue Scale




The M6S 4k write IOPS performance is faster than the M5P Xtreme but below some of the newer drives on the chart. We're actually quite surprised to see this level of performance from the Marvell 88SS9188 controller given its 4-channel design. At the high-end of the scale, the M6S nearly hits 84k IOPS.
