Back in February we showed you a rumor regarding WD's 5 mm thin hybrid hard drives, and now WD has delivered.
Two versions will be hitting the market, currently only in 500 GB variants. For starters, a plain hard drive will arrive. It is the WD5000MPCK, otherwise known as the WD Blue 5 mm ultra slim drive. Due to its thinness, it should be very appropriate for use in ultrabooks and ultraportables, unlike thicker 7 mm or 9.5 mm 2.5" hard drives, which are too bulky and take up too much room.
The second version that will arrive is the WD Black SSHD. While little has been detailed about it, we know that it'll come in at least a 500 GB version and carry a bit of onboard NAND to act as a caching SSD. The amount of NAND memory remains unknown, but the rumor from February indicated that it would carry around 24 GB.
These two drives will also be some of the first that will feature the SFF-8784 edge connector.
MSRP pricing for the 500 GB 5 mm 2.5" WD Blue drive will be $89, with no word yet on pricing for the WD Black SSHD models.
