Anvil Storage Utilities

 

Version and / or Patch Used: RC6

 

So, what is Anvil Storage Utilities? Anvil Storage Utilities is 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

Compressible and incompressible data flow at nearly the same rate on the M6e Black Edition.

 

 

Low Queue Depth Read IOPS

The Black Edition drives with firmware 1.05 have better random performance than the original M6e. Plextor released firmware 1.04 to the public for the original M6e, but that firmware increases the random performance, and also allows the M6e to use PlexTurbo 2.0.

 

4K random performance is important because roughly 70% of your reads and writes occur at this block size. The M6e Black Edition 256GB is an improvement over the original M6e, but is still at the bottom end of the list.

 

High Queue Depth Read IOPS

High queue depth 4K reads are less important for our analysis since most of us rarely get into the high queue depth range. SSDs are so fast that you would need to really work the drive hard to get into a queue depth this high.

 

Low Queue Depth Write IOPS

Again, the Black Edition is faster than the equal capacity M6e at random tasks, thanks to newer firmware. The 256GB model trails only slightly behind the 512GB drive, but falls well behind the XP941 256GB drive until we get to QD4.

 

High Queue Depth Write IOPS

It's easier to get into higher queue depths when writing data since our PCs log so much of what we do. At high queue depths, the Black Edition is quite a bit faster than the XP941 at writing random 4K data.
