CoolBananas ShockProof Case for External Hard Drives to 6.35 cm (2.5 inches) (Accessories)
In principle, a good bag. The padding consists of a 0,5 cm thick foam which yields to pressure and returns to its original shape after a few seconds. My hard drive lxbxh 11cmx7,8cmx1,5cm fits very well in the width, the length is still 2.5 cm square.
