WD released a very interesting drive with 2.5″ form factor and 9.5 mm z axis: a 120GB SSD flash NAND paired with a 1TB mechanical disk drive. As what WD says, the Black² dual drive is perfect for consumers and service providers to upgrade notebooks, small form factor desktops, gaming PCs and even AIO systems. They did point out that this drive is designed for enthusiasts, creative professionals, gamers and PC builders, so one could imagine that this will be a pretty interesting unit to own. Too early to say since we haven’t tested it… yet!
The dual drive comes under WD Black label, so you could understand that this drive is made for high performance. Unlike SSHD which comes with a smaller Flash made for the sole purpose of being used as a cache, you’re getting a large storage flash most likely where you could configure it to store higher priority programs and OS, and the rest on the mechanical drive.
Its hard to say how it works at this point, but the drive is bundled with a software and a web key, USB to SATA transfer cable and a warranty booklet. Just like Cache SSDs, this would require you to have an internet connection for installation.
