Anvil Storage Utilities


Version and / or Patch Used: RC6


So, what is Anvil Storage Utilities? Anvil Storage Utilities is 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, has been updating the software steadily on several international forums, and is adding new features every couple of months.


We can use Anvil 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




Compressible and incompressible data flow at nearly the same rate on the M6e Black Edition.



Low Queue Depth Read IOPS




None of the native PCIe drives we've tested to date have managed to break the 10K random read IOPS mark, but the M6e Black Edition does compare better to the XP941 now that the firmware has been updated. From an end-user point of view, you wouldn't be able to notice a difference between the M6e Black Edition and the XP941 when reading random data.


High Queue Depth Read IOPS




At high queue depths, the M6e Black Edition trails behind the XP941 512GB, but most of us will never load a SSD enough to get into these high queue depths.


Low Queue Depth Write IOPS




With random data writes, the Black Edition does well against the XP941 again. The new firmware is also a major upgrade over the original M6e release firmware.


High Queue Depth Write IOPS




The Plextor M6e Black Edition does very well at high queue depths, and moves the performance outside of the SATA 6Gb/s bounds.
