Portable data storage drive cartridge

A portable data storage drive cartridge has external interfaces positioned respectively at opposite ends of a cartridge shell. They may be arranged to be similar when the cartridge is rotated end over end to a reverse direction with respect to the opposite ends. A data storage drive, such as a magnetic disk drive assembly, having an interface, is positioned in the cartridge shell with the drive interface positioned toward a first end and away from a second end of the opposite ends of the cartridge shell. Flex cables extend from the drive interface, a first extending from the drive interface around the drive to the external interface at the second end of the cartridge shell, and a second extending from the drive interface, initially around the drive toward the second end, and reversing direction and extending back to the external interface at the first end of the cartridge shell.
