- gnfargbl 6y agoFrom what I've read, the issue is that the reduced performance has a direct effect on stability: When used as part of a RAID array then these disks can exhibit unexpected long pauses under load, which causes the RAID controller to mark them as faulty and kick them out of the array. There are quite a few stories of people being unable to use these HDDs for archival, for this reason.
- Jolter 6y agoIf you use them as JBOD, they should be perfectly stable, just a little slower at writing than at reading. But as said by sibling, not stable in a RAID.
- AmVess 6y agoI have a big pile of them in JBOD for use as storage only and they are fine. Most of mine are SMR and I wouldn't have known so until I looked them up.
- marcan_42 6y agoSMR isn't "a little slower" depending on your workload, but massively slower (RAID rebuilds are just one example). Do not buy SMR if you have any kind of write-heavy workload, or if you rely on consistent performance (e.g. any kind of streaming / latency sensitive usage).
