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

Previously, we stated that Plextor traded some sequential performance for increased random performance through firmware updates. Here we see that even the 128GB Black Edition is faster than the original 256GB M6e at QD1 random reads. Aside from the original M6e, the 128GB Black Edition gave us the slowest random read results on the chart.

 

High Queue Depth Read IOPS

Moving higher into the queue depth scale, the M6e Black Edition does scale well as the load increases. The high queue depth random read performance is right around the same mark we are able to achieve on premium SATA 6Gb/s products like the Samsung 850 Pro and SanDisk Extreme PRO.

 

Low Queue Depth Write IOPS

The 128GB M6e Black Edition is slower than the 128GB XP941 at QD1 random writes, but closes the gap by QD1. By QD4, the Plextor is actually faster than an equal sized Samsung SSD.

 

High Queue Depth Write IOPS

In the high queue depth random write range, the Plextor drives tower over the Samsung SSDs. Sadly, most normal PC users will never get into the high queue depth range because SSDs are so fast that commands don't get a chance to stack up this high while waiting to be executed.
