ADATA Premier Pro SP920 512GB 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 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.


The software can be used 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




The SP920 writes compressible and incompressible data at the same rate.



Read IOPS through Queue Depth Scale




Here we're looking at the read IOPS performance from queue depth 1 to QD32. ADATA rates the SP920 512GB at 98,000 IOPS, and we hit that target and then some. Getting to high queue depths, though, is nearly impossible under a consumer load, so we're concerned with the low queue depth performance. At QD1, the Premier Pro SP920 512GB delivers just over 8,300 IOPS, and that nearly double at QD2 and then doubles again at QD4.


Scaling Write IOPS through Queue Scale




The QD1 write IOPS ring the bell at nearly 37,000 IOPS, just behind the OCZ Vector. Again here, the QD2 IOPS nearly double the first test, but random write performance starts to fall off after QD4, but that's fine since we're already knocking on the door of the drive's limit of 88,000 IOPS.
