There are two inviolate rules of hard drives. The first is that you can never, ever have enough storage space, and the second is that your drive can never be tiny enough. Electronista reports that Western Digital has today launched a new 750 GB mobile HDD. This 2.5” SATA II drive can fit into the 9.5 mm slots in most notebooks.

This drive has an 8MB cache and claims to use a new advanced recording format that puts data in larger partitions, which gives the drive more total usable space. That means the drive is unlikely to work on XP, but should be perfect for Windows 7 and the like. Alone, this drive will set you back just $149.
