HardwareZone checked out a hard disk drive from the pretty unknown ExcelStor:

The new ExcelStor GStor Plus hard disk drive may look like just another storage product on the retail shelves, but its built-in features would, in many ways, be very attractive to even an average user. Essentially, the firmware of the drive has built-in capabilities that allows a user to configure multi-boot partitions, set hardware security encryption and even create a roll-back restore feature.
