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 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.
We can use Anvil 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
The XP941 doesn't lose performance going from compressible to incompressible data. This means you will not lose write speed when working with audio, video or highly compressed files in RAR and ZIP packages.
Low Queue Depth Read IOPS
Surprisingly, the 256GB model delivered the highest QD1 4K IOPS performance. The difference between all three XP941 drives is quite small and I doubt anyone would actually notice.
High Queue Depth Read IOPS
At high queue depths, the three XP941 drives all fall into place by the capacity size. It should be noted that all three XP941 drives manage to outperform the best SATA III drives at high QD. The 256GB model turns in 125K IOPS and the best SATA III drives all stop at roughly 100K.
Low Queue Depth Write IOPS
Random data writes is where we see the largest distinction between the three XP941 drives. All three drives hit roughly 32K random IOPS at QD1. The 128GB model starts to roll off at QD2, delivering just over 41K IOPS, while the two larger models hit 54K and 56K. The 256GB XP941 starts rolling off around 57K at QD4, but the large 512GB model keeps going to 78K at QD4.
High Queue Depth Write IOPS
By the time we get to QD8, most of the XP941 drives have reached or nearly reached the wall. The 256GB model gets up to 64K IOPS at QD8, and then starts to roll back due to latency, as the commands stack up.
