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.

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.

Incompressible Data

Compressible and incompressible data flow at nearly the same rate on the SM951.

Low Queue Depth Read IOPS

We often talk about the importance of consumer SSDs hitting 10K random read IOPS at QD1. To date, very few products are able to achieve that mark, most of them are from Samsung. The Samsung SM951 sets a new bar, just over 12K random IOPS at QD1. The drive scales very well too, nearly 50K IOPS at QD4.

High Queue Depth Read IOPS

Samsung's own specification documents states the SM951 only scales to 90K read IOPS, but in our testing, we achieved over 180K, twice the rated specification. That result came at QD32, but it also held 180K all the way up to QD128 (not plotted on the chart today).

Low Queue Depth Write IOPS

If that wasn't enough to get your attention, the SM951 also blows past the other PCIe M.2 products in random writes. Our QD1 random write result was over 40K, but even more impressive was the result at QD4 - over 100K.

High Queue Depth Write IOPS

We only scaled the chart to QD32 but managed to hold the 105K random write IOPS rating all the way to QD64. This is also much higher than Samsung's random write rating of just 70K IOPS on the specification sheet.
