Corsair Force LS Series 240GB SSD 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

CrystalDiskMark CrystalDiskMark Grid

Install Results: The Force LS does better on this benchmark in the writes department breaking the 400MB/s mark while reads are still very strong. The 4K numbers are also very competitive.

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.

IOPS Reads

IOPS Writes

Install Results: The reads IOPS were dramatically lower than the writes which is something we’ve seen before but it’s not typically the case. Still, the read score is not shabby and the writes are very good so overall nothing to complain about.

    Thanks a lot for the review! I’ll definitely buy this one.
