hello ppl, What do you guys think of Raid 1 in an external hdd? I think that, obviously, with two drives, there's a hdd to fall back on if one fails. But surely, when it's "times-up" for one hdd, the second one can't be very far off? also, they're subject to the same stress, ie, temperature, amount of writing work, etc. care to throw in a few thoughts? thanks!
