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.

The software can be 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 Extreme PRO writes compressible and incompressible data at the same rate, so you will not lose performance when working with pictures, compressed audio, or video files.

Read IOPS through Queue Depth


The magic number every company shoots for is 100k IOPS at QD32. It's a good target, but one that most of us shouldn't be concerned with as we rarely reach such a high queue. We look for low queue depth performance, highlighted in red on the charts. Our magic number is 10k IOPS at QD1 and a nice scale as depth doubles. The Extreme PRO 480GB gets very close to the 10k IOPS performance rating at QD1 and nearly doubles at QD2 and then QD4. This is exactly what you want to see in a consumer SSD.

Write IOPS through Queue Depth


The Extreme PRO 480GB delivers just over 33k write IOPS at QD1, and the drive scales well as the depth increases. We hit just over 86k write IOPS in our test system running at stock i7-4770K clock speeds. An overclocked system would achieve SanDisk's 90k write IOPS claim.
