Anvil Storage Utilities
Version and / or Patch Used: RC6
So what is Anvil Storage Utilities? First of all, it's a storage benchmark for SSD's and HDD's 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
16KB Stripe (Left) / 64KB Stripe (Right)
When looking at several read results we get better performance with a 64KB stripe size after running several different tests. This is a result of the flash taking less abuse.
Read IOPS through Queue Depth Scale
Here we get three sets of numbers. The single Seagate 600 SSD 240GB was added to the list so we can see exactly where RAID increases IOPS performance. Here we see that low queue depths don't see an increase in performance and performance doesn't increase until we get to higher read queue depths.
Scaling Write IOPS through Queue Scale
The performance increase with RAID happens at a lower queue depth when writing data. Here we see an increase at QD4 and the IOPS increase is quite significant. We also see the random write increase that comes with a smaller stripe size.
