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. The author, 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 Samsung 850 EVO 1TB doesn't perform any differently when working with incompressible data. The read and write performance is the same with incompressible and compressible data.

Low Queue Depth Read IOPS


We didn't quite get to 10K random read IOPS with the 850 EVO 1TB SSD. We did break 10K IOPS at QD1 with the 250GB 850 EVO.

High Queue Depth Read IOPS


The 850 EVO scales very well, all the way to 97K IOPS in our test with 1GB of data written to each drive for each queue depth.

Low Queue Depth Write IOPS


High Queue Depth Write IOPS


The write performance for the 850 EVO 1TB is also very high. We measured nearly 84K IOPS at QD4, and across all random write tests, the 850 EVO nearly mimicked the 850 Pro step for step.
