MyDigitalSSD BP4 240GB mSATA 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




A number of changes came with the new Phison S8 firmware, one of which is higher performance with compressible data and slightly lower performance with incompressible data.


We never received an answer when asked if a compression method was introduced, i.e. SandForce like algorithms. For now, we can just say that the BP4 performs differently when working with different types of data.



Read IOPS through Queue Depth Scale




We haven't tested many mSATA SSDs after introducing some of our new tests. That takes us back to the moment we realized we'd missed several 128GB class SSDs and went on a sample spree to catch up. We're now in the process of collecting mSATA drives for review purposes.


The MyDigitalSSD BP4 240GB increases read IOPS rapidly and where it matters most to a majority of users, at low queue depths.



Scaling Write IOPS through Queue Scale




Then we get to the 4K write IOPS and discover a brick wall at roughly 27K IOPS.
