Western Digital Black2 Dual Drive Full Review - 120GB SSD + 1TB HDD in a single 2.5" package
Introduction, Specifications and Packaging
If you're into the laptop storage upgrade scene, you hear the same sort of arguments all the time. "Do I go with a HDD for a large capacity and low cost/GB, but suffer performance"? "I want an SSD, but can't afford the capacity I need"! The ideal for this scenario is to combine both - go with a small capacity SSD for your operating system and apps, while going with a larger HDD for bulk storage at a lower cost/GB. The catch here is that most mobile platforms only come with a single 2.5" 9.5mm storage bay, and you just can't physically fit a full SSD and a full HDD into that space, can you? Well today Western Digital has answered that challenge with the Black2 Dual Drive:
Yup, we're not kidding. This is a 120GB SSD *and* a 1TB HDD in a single package. Not a hybrid. Two drives, and it's nothing short of a work of art.
Specs are a tad complicated here. WD lists the rated throughput of the SSD portion on their spec sheet:
- Interface: 6Gb/s
- Read: 350 MB/s
- Write: 140 MB/s
That's all good and fine, but we also might want to know the specs on the HDD portion. I'm going to see into the future and predict that it's a WD10SPCX 1TB Slim Series HDD, which is technically a Blue drive spinning at 5400 RPM. Here are the relevant specs for that drive:
- Interface: 6Gb/s
- Transfer rate (max): 140 MB/s
- Average latency: 5.5 ms
- Cache: 16 MB

WD has taken a wild departure from their normal packaging with the Black2:
Included is a USB key that is ironically not a storage device - it simply acts as a virtual keyboard and launches the WD Black2 web site (this link) so you can download the most recent version of the driver as well as cloning software. Also included is a detailed quick start guide book (in 20+ languages) and a USB to SATA adapter for OS cloning purposes.
