At raid6, rebuilds are 4.2 roentgens, not great but they’re not horrible. Keep old backups.but the data isn’t irreplaceable.
Raid5 is suicide if you care about your data.
Comment on When can we expect 500TB drives to be available?
9point6@lemmy.world 1 month agoI guess you’re expected to set those up in a RAID 5 or 6 (or similar) setup to have redundancy in case of failure.
Rebuilding after a failure would be a few days of squeaky bum time though.

Absolutely not. At those densities, the write speed isn’t high enough to trust to RAID 5 or 6, particularly on a new system with drives from the same manufacturing batch (which may fail around the same time). You’d be looking at a RAID 10 or even a variant with more than two drives per mirror. Regardless of RAID level, at least a couple should be reserved as hot spares as well.

Yeah I have 6 14tb drives in raid 10, I’ll get 2 more if i need it.
