WD Black² Dual-Drive 120GB SSD + 1TB HDD Hybrid 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.

Benchmark Results: More of the same here but the 4k writes actually hold their own with the SSD crowd, even besting a few.

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

Benchmark Results: Not super strong results for IOPS, especially in the writes department but this is not really a drive that’s focused on IOPS performance but rather increased performance with ample storage.

    A quick look at today’s prices. The Crucial M500 960 GB around $470-570. Which mean this makes sense, if you need it.
    It also means all those fancy laptops without an optical drive to exchange for a HHD/SSD caddy lose out, as do those requiring 7mm Drives.

    As far as I’m concerned, the WD Black2 is only a viable option if you:

    * Must have an SSD and a hard drive
    * Only have one drive bay available

    Otherwise, it’s grossly overpriced and underpowered. I can easily get a 120GB SSD and 1TB, 7200 RPM, 2.5″ hard drive that will run circles around this thing for less than 2/3 the price.

      you forgot the third option – “because you’re rich”

      • Zlý Medvídek Míša

        rich people buy best ssd smartass…lets say revodrive? :) twice the speed of usual ssd…

        • James Cook

          Not where i work, the rich buy whatever the hell they want + wasn’t trying to come across as a smartass. Just stating the truth

      seriously though. If this was reasonably priced (and maybe it will be in time), OEMs and consumers would be all over this.
