Are you just using striping? A failed drive would be bad then, X times (where
X is the number of drives) worse than a normal single drive failure. It's
important to remember that drives fail completely and suddenly sometimes in any
case. I'm building a file server for my house and plan to use raid6 to
mitigate that issue, It also allows me to comfortably use refurbished drives (6
of the 4 tb htsg drives, $60 ea. on ebay). I am keeping a spare drive just in
case, and I used multiple sources so the drives will hopefully be less likely
to fail in a group over a short time. It'll still be very fast and near the
limit of my Gb/s network.
