With pockets for hard drives, there are two possibilities. They are small but not shockproof. Or they are a little larger and protect the hard disk. Unlike other bags, this has a more solid outer shell / shell. Characterized it is a little large, but this is not a disadvantage for me. It even fit 2x 2.5 "drives in a pocket. Where there is a bit tight. The protection is of course no longer be guaranteed. I have now ordered a second me.
