OCZ ARC 100 Series 240GB Value 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.


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




The performance with compressible data and incompressible data is the same, so you don't have to worry about performance loss while editing audio and video files.



Low Queue Depth Read IOPS




We haven't updated the firmware on our Vertex 460 or Vector 150, but we suspect both have a performance increasing firmware available. The ARC 100 actually has higher QD1 random read performance than the higher spec models with launch day firmware on all three. The low queue depth read scales really well too.


High Queue Depth Read IOPS




It's rare to reach high queue depth random reads in a consumer environment, but we still run the tests. The ARC 100 does a better than OCZ's claimed 75,000 random IOPS at QD32. Our test is a little different than OCZ's test though.


Low Queue Depth Write IOPS




Again, we really need to update the firmware on our Vector and Vertex products. Our ARC 100 Series 240GB does better than Vector 150 240GB at QD1 random writes, but falls a bit behind Vertex 460. By QD4, the Vector 150 fall in line with the random performance we expect, but the ARC 100 isn't far behind.


High Queue Depth Write IOPS




I have to wonder if OCZ tested QD32 random writes when specifying 80K IOPS for ARC 100. In our test, the IOPS regressed at QD32 from QD16. We see this happen quite often as the latency becomes large enough to slow IOPS performance. At QD16, we hit 85,678 random write IOPS.
