VisionTek Data Fusion PCIe SSD 240GB Review
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: Similar to the AS-SSD benchmark, the incompressible data slows things down a bit in the writes department as real-time data compression loses effectiveness. Curiously, the 4k numbers are weaker than expected in the writes department, failing to meet that of the SATA III drives in the comparison.
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: Very strong IOPS performance with the writes and moderate performance on reads – we expected a little better on that piece.
