A new, pint-sized, 15,000-RPM hard disk drive has just been released to the market. It's a fast little product from Western Digital's HGST that is a capacity match for traditional enterprise 3.5-inch drives. Fitted into only a 2.5-inch form factor, however, the Ultrastar C15K600 boasts more than double the performance of existing drives.
The product doesn't come with a Fibre Channel interface, so it isn't a complete throwback to the good old days. But it ships without onboard flash or any of the other new industry tricks, such as helium filling.
The question is, "Who needs it?" That's not pejorative, but this drive goes against the current wisdom of the disk drive business. It's generally accepted that superfast SSD or flash arrays will overtake the market for enterprise performance storage -- a process that's already happening.
