WD Black 2 Dual-Drive SSD+HDD Hybrid Review

Article Index:   

Next we ran SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison SSDs. The benchmarks were run without formatting and read and write performance metrics are detailed below.

SiSoft SANDRA 2012
Synthetic HDD Benchmarking


According to SiSoft SANDRA's physical disk benchmark, the WD Black 2 SSD offers strong read performance, but its write speed trails the other SSDs significantly.

ATTO Disk Benchmark
More Information Here: http://bit.ly/btuV6w

ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.


Because the ATTO Disk Benchmark requires that drives be partitioned and formatted, we're able to test the performance of both the WD Black 2's SSD and HDD. As you can see, the SSD portion of the drive offers decent performance in the read tests, but still trails the standalone SSDs. In the write test, the WD Black 2 is way behind.  The HDD performs relatively well, however, and consistently offered transfer speeds over 110MB/s, once block sizes exceeded 8K.

Unless you absolutely need more than 500gb for your OS and all the other stuff, a 500gb ssd would serve you better. Heck, i only paid $290 for a 500gb Samsung Evo on Newegg a month ago and that blows the doors of this drive. This drive should certainly be priced less than 200 considering most 128gb ssds hover around $80.

I read that this drive does not work on Nvidia chipsets and it is also not mac compatible, any chance either of these 2 things were tested?

sevgas, no, these two setups weren't tested. NVIDIA chipset motherboards especially are a pretty long shot these days and old hardware. Mac on the other hand would make sense to look at but it is a PC-targeted product so I wouldn't be surprised if the drivers weren't there yet.

Thank you for the response Dave!

I know nvidia chipsets are rarer these days but I actually (and unfortunately) know several friends still running Athlon X2's lol.

As this is a mobile product and apple is more and more soldering it's mobile parts together making it impossible to add a drive yourself. I have an Air with an msata 256gb so it would be nice if apple would supppprt a product like this even if it has to permanently integrate it into the design.

I've had an inexpensive NVIDIA chipset (N68) in a pc here for years. It gave up the ghost a week ago (bad caps) and I replaced the motherboard with another cheap chipset in it. It's an ECS A960M-MV and it looks like a quality board. (solid Japanese caps) It was $22.98 Shipped from Newegg.

I couldn't believe that price.

Seems like a decent package although I am not a huge WD fan

Here is the result i Get ....

I buyed one during instalation of windows i got bluescreen!!!!!!!!!

Anyway i continued the instalation but after on it continued bluescreen..

So i went to my dealer after 2 week they sent me a new one¿¿¿

So far it doesnt have the performance they promissed....

(I have an Hp 1247et Notebook im sure a newer note or pc will have better performance but how much? i dont know)
