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


With compressible data, the PNY Prevail is a high performer. SSD manufacturers wish they could achieve this level of performance all of the time, but sadly few do. The drive loses some performance when moving over to incompressible data.

We read forum posts every week from people complaining about the incompressible performance, but a 4,462 score is actually very good. You won't hear owners of SSDs with LSI SandForce controllers complaining.

Read IOPS through Queue Depth Scale


I think this is the first time a SF-2281 controlled drive paired with MLC flash has produced a 10K IOP QD1 run in our read test. The Prevail sample has the latest firmware from SandForce and it looks like the team has tuned the drive a bit more for consumer experience.

The read IOPS scale well with additional queue depth added, but Prevail doesn't hit the 85K claimed performance on the specs sheet.

Scaling Write IOPS through Queue Scale


The 4K QD1 write IOPS test shows that most of the drives performance in the low 30K IOPS range. The Prevail 240GB scales well as the depth increases, all the way to 83K IOPS.
