Anvil Storage Utilities


Version and / or Patch Used: RC6


So what is Anvil Storage Utilities? It's a storage benchmark for SSDs and HDDs that allows you to 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




Incompressible Data




The performance doesn't decrease when changing between compressible and incompressible data.


Read IOPS through Queue Depth Scale




Samsung lists 10,000 IOPS for 4K reads, and in our test we get very close to that spec. The 840 EVO and 840 Pro dominate the low queue depth read IOPS tests.


Scaling Write IOPS through Queue Scale




Write IOPS at low queue depth performance are also very high with the 840 EVO. TurboWrite makes this possible, since TLC normally has higher latency than MLC.
