Plextor M5 Pro Xtreme 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 DQ16.


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 is used several different ways and 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 M5 Pro Xtreme doesn't change performance when working with different data types. Here we scored nearly identical results with compressible and incompressible data.



Read IOPS through Queue Depth Scale




In the latency test we didn't see any difference, but here in the IOPS test we found what we were looking for. The 16KB page size means more data in each page so more to work with at the block level. This helps increase sequential performance, but reduces random performance. It's a lot like what we published about RAID stripe sizes months ago with the LSI 9265-8i RAID controller review. Unlike the RAID controller, the page size difference is very small when reading data back from the drive.



Scaling Write IOPS through Queue Scale




The same happens when writing data in all queue depth sizes other than 32.
