SanDisk Ultra II 480GB SSD Review

Anvil Storage Utilities


Version and / or Patch Used: RC6


So, what is Anvil Storage Utilities? Well, 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. Anvil has been updating the software steadily on several international forums, and is adding new features every couple of months.


We can use Anvil 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 SanDisk Ultra II actually delivered a little higher performance with incompressible data. This is a nice change from having significant performance loss with incompressible data.


Low Queue Depth Read IOPS




The Ultra II 480GB scales well in our random read test that doubles queue depth with each test. The drive still doesn't meet the same 10K IOPS QD1 mark of the Samsung 840 EVO though.


High Queue Depth Read IOPS




Most of us will never actually get to high random read queue depths, but if you manage to pull it off, the SanDisk Ultra II can deliver 95K IOPS at QD32.


Low Queue Depth Write IOPS



The Ultra II 480GB does really well writing random 4K data thanks to the SLC buffer.


High Queue Depth Write IOPS




Up top, the Ultra II 480GB hits just over 81K IOPS at QD16.
