Apple updated their Time Capsule to a bigger size reservoir last week, which now comes with 2TB-3TB. They also listed these as “Serial ATA server-grade hard disk”, standard equipment on the device’s official spec sheet. And well, HardMac opened it up to find something else.

It’s generally assumed that for a drive model to be qualified as “enterprise,” it must sustain a mean time between failures — MTBF for short — in excess of one million hours. So what’s the MTBF for the Western Digital’s WD20EARS (Caviar Green) in HardMac’s Time Capsule?

Conveniently, the hard drive maker wouldn’t say. Of course, we guess the definition here is up for interpretation, but given past experiences with the wireless backup gizmo, we’d certainly hope this improved revision fares better.
