WD Black2 SSD/HDD

 
WD's Black2 SSD/HDD combo drive promises to solve the capacity-versus-speed storage conundrum

When it comes to storage, many of us struggle with the decision whether to buy speed or capacity. An SSD delivers speed aplenty, but you need a mechanical hard drive for capacity. Buy the SSD and rely on the cloud, or opt for the hard disk and just turtle along? Western Digital's Black2 combo SSD/HDD promises to deliver speed and capacity. 

Marrying a 120GB solid-state drive and a 1TB mechanical in a single 2.5-inch, 9.5mm package, the Black2 fits in most laptops. Owners of thin-and-lights, on the other hand, won't benefit because that form factor typically accomodates only thinner, 7mm drives. 

WD's Black2 drive marries a 120GB SSD to a 1TB HDD that and fits in a 9.5mm bay. It uses a single cable to connect to most SATA 6Gb/s drive controllers.

The Black2's SSD and HDD are treated as separate drives, with the idea that you install the operating system, applications and frequently used data on the SSD and everything else (large files, movies, music, etc.) on the hard drive. Basically, what desktop and two-bay laptop users have been doing with separate drives since the advent of the SSD. It works far better than the hybrid concept (a hard-disk drive with a large NAND cache), which has never delivered on performance promises in  real-world tests. 

There are a few Black2 caveats: WD highly recommends a fresh OS install; the drive doesn't support Nvidia or ASMedia storage controllers, or the Mac; and it can't be used in RAID arrays due to the software component required to access the hard drive—only the SSD is visible without the driver. Mac users might get a driver down the road, but don't hold your breath on the other controllers; their relatively insignificant share of the mobile market doesn't warrent the effort, The driver isn't shipped in the rather stylish retail box, WD instead provides a USB flash drive that takes you online to download the software. 

Being the only current product of its ilk, the Black2 is a tad pricy: $299 (about 26 cents per gigabyte). That's about $70 more than a 128GB SSD and a 1TB, 2.5-inch hard drive cost separately—not that you could fit both in the typical laptop or all-in-one. Regardless, the Black2 could be a boon for a lot of many users. 

Stand by for a review in the near future, and we'll tell you how the concept actually performs.
