SanDisk Extreme II 120GB 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 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




Incompressible Data




When comparing incompressible to compressible performance, we didn't notice a large difference moving between file types.



Read IOPS through Queue Depth Scale




Companies like to talk about their high queue depth IOPS performance, but in the real-world, most of us rarely hit a queue depth higher than 4. QD8 would be like a biblical event under normal desktop use. It's that reason we came up with showing low queue depth IOPS performance.


The Extreme II trails the 840 Pro in 4K reads ever so slightly at low queue depths and is faster than the OCZ Vector. At this point I'm comfortable in saying we have a true contender for the performance crown in this capacity size.



Scaling Write IOPS through Queue Scale




When writing 4K data the Extreme II is right with the 840 Pro in QD1 and QD2. Vector has a nice lead in these tests, but we know OCZ plans to replace Vector with Vector 150 in Q3, and if OCZ continues down the same path as Vertex 450, then the Vector 150 will be 20nm.
