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




Unlike the other DRAM-less controllers in the wild today, the Toshiba THNSNF doesn't slow when working with incompressible data. The THNSNF actually manages to go a little faster when working with incompressible data.


Read IOPS through Queue Depth Scale




Here is another set of new tests for 2013. Here we see IOPS performance at various queue depths. Companies like to advertise their IOPS performance at high queue depths, but most end-users don't get to high queue depths. On the chart we highlight the lower queue depths - 1, 2 and 4. On the chart are three drives that may see adaption in the OEM market. The MyDigitalSSD is a new Phison controlled model with even newer Toshiba 19nm Toggle 2 flash with 16K page sizes.


Scaling Write IOPS through Queue Scale




When writing data you get to higher queue depths when multitasking, but still the lower queue depths are used more than higher queue depths.
