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
The SandForce compression algorithm means the drive writes incompressible data slower than it does compressible data. You can see the affect in the two images above. We saw a loss of around 800 points in Anvil. This is a lower margin than many of the other SandForce based drives, we generally expect to see around a thousand point loss.
Read IOPS through Queue Depth Scale
The OCZ Vector 3.20 does well at low queue depth IOPS and scales to just over 60K read IOPS at a queue depth of 16.
Scaling Write IOPS through Queue Scale
The low queue depth write IOPS is very good as well. At a single queue depth, the Vertex 3.20 runs very close to Vector and the 840 Pro, both 256GB.
