SanDisk Extreme PRO 240GB SSD Review

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




SanDisk advertised 100k random read IOPS, and we got very close to that result with our stock clocked system. We like to look at the low queue depth performance anyhow since most users rarely achieve high queue depths under normal workloads. The Extreme PRO 240GB nearly breaks into the magic 10k read IOPS area at QD1. The drive scales well as command queue increases, and we see nearly 20k read IOPS at QD2.


Write IOPS through Queue Depth




Random write IOPS performance starts out strong on the Extreme PRO 240GB and finishes near 90k IOPS at QD32. In our quick burst of 4k data, several drives manage to outperform the Extreme PRO in this test, but few can sustain high levels of performance for a long period of time.
