Have you taken into account the fact that a 2TB drive has more bits than
1/(error rate)? Thus, your chance of bit error while reading the
entire drive is > 1, thus (in theory) you could never successfully
rebuild your RAID array? Personally, I'd only use maximum capacities
of 500 to 750GB or so in my RAID drives.
