SanDisk Extreme II 240GB RAID 0 SSD Report

Anvil Storage Utilities


Version and / or Patch Used: RC6


So what is Anvil Storage Utilities? First of all, it is 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 QD16.


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




An Anvil score of 11,000 clearly shows why we consider the SanDisk Extreme II one of a handful of "Hyper-Class" SSD's.



0-Fill Compressible Read IOPS through Queue Depth Scale




Mirroring our ATTO read results, we find the Extreme II outperforming the other arrays on our chart as commands stack up.



0-Fill Compressible Write IOPS through Queue Depth Scale




Write caching enables our array to put out nearly three times the performance of a single drive at 4K QD1. SanDisk designed the Extreme II to provide superior write performance at low queue levels, peaking at 4K QD2 - 4K QD4. We like this approach because the vast majority of commands are executed in this range.


Compression 100% Incompressible Data




Overall, the Extreme II is slightly faster when digesting compressible data.



Incompressible Read IOPS through Queue Depth Scale




Both our Extreme II arrays are faster than the other arrays on our chart when reading data, especially as commands stack up.


Incompressible Write IOPS through Queue Scale




Writing incompressible data does change the Extreme II's performance significantly in comparison to writing compressible data. If you want to split hairs, the Extreme II two drive array comes in just behind the EVO and 600 two drive arrays. As we would expect to see, our three drive array blows away the two drive arrays at QD2 - QD4.
