WD Black 2 Dual-Drive SSD+HDD Hybrid Review - HotHardware

WD Black 2 Dual-Drive SSD+HDD Hybrid Review

6 thumbs up

Our Test Methodologies: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. Out testbed's motherboard was updated with the latest BIOS available as of press time and AHCI (or RAID) mode was enabled. The SSDs were secure erased prior to testing, and left blank without partitions for some tests, while others required them to be partitioned and formatted, as is the case with our ATTO, PCMark 7, and CrystalDiskMark benchmark tests. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system, ensured all temp and prefetch data was purged, and waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test.

IOMeter
I/O Subsystem Measurement Tool

As we've noted in previous SSD articles, though IOMeter is clearly a well-respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs. The fact of the matter is, though our actual results with IOMeter appear to scale properly, it is debatable whether or not certain access patterns, as they are presented to and measured on an SSD, actually provide a valid example of real-world performance for the average end user. That said, we do think IOMeter is a reliable gauge for relative available throughput within a given storage solution. In addition there are certain higher-end workloads you can place on a drive with IOMeter, that you an't with most other storage benchmark tools available currently.

In the following tables, we're showing two sets of access patterns; our custom Workstation pattern, with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and IOMeter's default access pattern of 2K transfers, 67% reads (34% writes) and 100% random access.

The WD Black 2 SSD offers consistent performance in the access patterns we tested, but it trailed the standalone SSDs by a significant margin.

In terms of actual transfer rates, the WD Black 2 also trails the other drives we tested, though it is in the same league as the SanDisk drive here.

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)
