Primarily, I would recommend the drive for backups as system disk, there are certainly better, for example, a solid state disk. The strengthening of WD10EZEX are volume and energy consumption. A pity I think that nowadays not even enclosed screws in the hard drives. Just when you really ordered as an upgrade for large NAS server. And no screws since has.
Still 5 stars, instructions and description can be the manufacturer as PDF, bolts, there are not yet digitally.
