  • A single drive is always going to be a potential point of failure. Definitely make periodic backups to a different device if you don’t want to potentially lose everything on it without warning.

    There are more complicated solutions available, such as a RAID array, but it sounds like you want to keep things relatively simple. In that case, I don’t think there will be a whole lot of difference between 2.5 and 3.5 inch drives – except that there are 3.5 inch drives designed for data center applications which may net you some extra reliability. You’d likely need to get such a drive and put it into your own external enclosure, though.

    That said, there’s only so much you should expect to get out of a single drive connected via USB (relatively slower transfers, reliance on the bespoke external bay, potentially not getting warned if SMART status changes).
