OCZ Vertex 460 240GB SSD ReviewWed, Jan 22, 2014 - 8:00 AM
CrystalDiskMark & Anvil IOPS
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.
CrystalDiskMark 3.0.2 x64 – Intel Z77 Platform
Benchmark Results: This is very near the best performance we’ve seen from any drive on this benchmark – only overshadowed by the Samsung EVO drive and right on par with the Vector drive.
Anvil Storage Utilities 1.050 RC6- Intel Z77 Platform
Along with the move to a new platform, we decided to make a change in one of the benchmarks. There’s a relatively new benchmark called Anvil Storage Utilities that is in beta but close to production. It’s a very powerful tool that measures performance through a variety of tests which can be customized. Since some of the tests more or less duplicate what we get from other benchmarks we use already, we decided to use the IOPS (Input/Output Operations Per Second) testing on 4kb file sizes at a queue depth of 32. IOPS performance is something SSD makers tout quite a bit but we generally don’t do a lot of IOPS testing because frankly a lot of users can’t relate to IOPS metrics as well and it tends to be more meaningful to the enterprise/server crowd. Still, it is another performance indicator with relevance and while some drives post good MB/s numbers, their IOPS scores aren’t always commensurate which this test will prove out.
Benchmark Results: There is virtually no difference in the results from the Vertex 460 and the 450. The Vector does punch out a bit more on the reads but overall excellent performance.
