    case really too thin

    Hard drive is loose in the packaging, not even a spacer or bubble wrap, the drive seems ok but the case is really fragile.

    Super

    The hard drive is quiet and fast. It's been just over a year and I still have nothing to complain about.

    Conforms to product

    High transfer speed and large storage capacity. Excellent product for the advertised price, more attractive than an SSD storage key

    good for storage

    Bought to back up data, it's only used for writing. It's quite fast for what I do with it.
