There is enough storage space to hold two of my hard drives (Toshiba 1TB Canvio and Toshiba 3TB Canvio Advance), an SD Scandisk and a USB hard drive cable. It's a snug fit but I feel like they're all fully protected. It can be hand carried or worn on a pants belt, especially when traveling by air, and is not subject to damage or loss of digital integrity.
