SanDisk Extreme II 480GB 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 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 with Extreme II.



Read IOPS through Queue Depth Scale




To get big sensational marketing numbers, companies publish their high queue depth IOPS results. In the real-world, desktop users rarely achieve a queue depth higher than 4 and because of that we built our scaling IOPS charts.


True to the results we achieved with the Extreme II in other capacity sizes, the 480GB fits right in between Samsung's 840 Po and OCZ's Vector SSDs in the QD1 test. Extreme II 480GB and 840 Pro went back and forth up the depth scale with the Vector following close behind.



Scaling Write IOPS through Queue Scale




OCZ's Vector has amazing write IOPS at low queue depths and takes the lead in this test. Again Extreme II splits the two other hyper speed SSDs on the market. Oddly enough, after all of our ranting about 20nm write performance in the previous two reviews published today, Crucial managed to break into the top tier in this test.


As we stated in the other articles, if you want to get performance out of 20nm, you need ramp up the capacity size to get a lot of interleaving. Extreme II did well though all the way up to QD4. The drive doesn't scale much after QD4, but it's not an issue for desktop consumer users.
