MyDigitalSSD BP4 960GB SSD Review

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 DQ16.


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 is used several different ways and 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




When MyDigitalSSD switched over to new Type C flash, they also released a new firmware that manipulates compressible and incompressible data differently. Oddly enough, write performance doesn't change too much like what we see on LSI SandForce based drives. The big changes come when reading data.



Read IOPS through Queue Depth Scale




Manufactures like to publish their high queue depth IOPS performance, but in a desktop or notebook environment, it's rare to get anywhere near a queue depth of 16 with a SSD, much less 32. We've highlighted in red the low queue depth numbers and will focus on those.


The BP4 960GB ramps up quickly just like what we saw in ATTO. This drive is the 1QD champion for consumer drives and it keeps that lead all the way to QD4. At that point the 960GB model hits a wall, but that's fine since this is a consumer SSD and not an enterprise SSD.



Scaling Write IOPS through Queue Scale




The BP4 960GB reaches 20K IOPS at QD1, but it never gets much higher than through the queue depth range.
