Isn't that the wrong way around? Archives are write many, read maybe. I do regular backups that I hope I never have to read.
- otterley 7y agoI think it's a question of write vs. rewrite. Most archival backups are write-once in the sense that they're append-only, especially now that storage is so cheap nowadays (see: Amazon Glacier). SMR performs generally fine except in the physical rewrite case. A 6TB disk is unlikely to see a lot of physical rewrites except in this pathological case of a RAID rebuild that people are complaining about.
