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.

Benchmark Results: Again we see a nice jump in performance from the M550 over the M500 in every aspect of the benchmark. Very competitive performance overall.

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: The IOPS performance is perhaps the most impressive performance improvement over the M500 with results that are nearly double for both reads and writes. This is one of the few drives where we don’t see a large disparity between the reads and writes.

    Hardly ground breaking performance, but for the price it’s going to be giving samsung a run for their money!

    • Nathan Kirsch

      You’ll have to wait for NVMe drives or other PCI Express solutions to hit the market before you’ll see ground breaking performance again!

      • basroil

        Meant more on the line of 4k performance, but even that is largely limited by SATA interface. Sequential performance in SATA disks is no longer really a test, any good company already maxes out the interface (though reliability tests still are good)

        Once NVMe drives come out into the open market all hell will break loose though, we might see some ridiculous (ly expensive) drives come.
