- melted 11y agoRebuild time is a problem, I agree. But not as huge of a problem as outright data loss.
- snaky 11y agoRAID is not the solution for data loss problem, never was, never will. There is backup for that.
- melted 11y agoBackup is never current, and it takes time to restore. RAID has its place. So much so, in fact, that there are now erasure-coded distributed filesystems at Google and elsewhere, reliably storing exabytes of data on super shitty disks.
- mrb 11y agoNitpick: neither RAID 6, nor RAID 5 are an option. Leventhal's point is that triple-parity (eg. ZFS raidz3) becomes necessary.
- snaky 11y agoI think the main point is that there is no "RAID is the solution for all our problems" anymore.
