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 QD16.
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 can be used 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
Regardless of the data type, the 850 Pro 1TB delivers a bit over 5,600 combined score in Anvil's test. That means like other Samsung SSDs, performance doesn't drop when working with incompressible data.
Read IOPS through Queue Depth
Our 1TB sample from Samsung brushed right up against the 100K IOPS 4K read barrier as advertised. It's a nice metric for advertising but we're more concerned about the low queue depth performance. The Samsung 850 PRO achieves the magic 10K read IOPS mark at QD1. To date, very few SSDs, even PCIe SSDs, are able to reach that high. The 850 Pro scales very well too, nearly doubling IOPS with each pass as the queue depth increases to 4.
Write IOPS through Queue Depth
Several of the new generation consumer 1TB class SSDs handle random data writes well thanks to cache schemes like nCache, Turbo Write and functions built into L85C flash. This test uses bursts of small writes so everything stays within the cache range.
