A couple of years ago one of my co-workers lost a fair amount of data in a disc crash. To guard against a recurrence, he purchased a pair of 1 TB drives. One went into his computer as the primary drive. The other went into a USB3 external enclosure, and he used a backup program of some description to make periodic copies of his data to it.
This past week he lost the primary drive in his system. It makes a terrible whining noise when starting, then something in the drive (the heads, maybe) make a few "chunk" sounds, then the drive spins down again.
The backup drive? It was apparently a twin of the primary drive: same manufacturer, series, capacity and production run. It suffered the same failure at the same time.
He's lot a lot of data and may have to pay a recovery lab to get it back.
Moral of the story: purchase primary and backup drives from different manufacturers. Or if you want to use the same manufacturer, at least try to get different production lots.
