Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


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 is 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 LSI SandForce architecture means incompressible data writes are slower than compressible data writes. In the two charts above, we see the effect incompressible data has in a number of different tests. The most significant change comes in the sequential write category where incompressible data writes at around half of the speed as compressible data.



Read IOPS through Queue Depth Scale




This test shows the way queue depth effects performance of 4k reads (above) and writes (below). The RevoDrive 350 scales very well as the queue depth increases. OCZ's spec sheet claims 90k read IOPS, but we achieved well over 130k in our test at QD32.


Scaling Write IOPS through Queue Scale




I had to go back and run the test again to verify what I was seeing. OCZ claimed 140k IOPS at QD32, but we hit 240k on a drive that was already worn from previous tests.
