If you're using them to store media, SMR doesn't much matter.

Depends on how your array software works.

SMR only effects write performance, AFAIK. What am I missing?

Timing.

Timeouts on adding them to or rebuilding arrays.

#1313 (Beware of SMR drives in CMR clothing) – smartmontools

www.smartmontools.org

 

[Domon]

Explain

he runs ZFS. ZFS will drop SMR drives like theyre hot constantly due to timing out of write actions.

While all three CMR drives comfortably completed the resilver in under 17 hours, the SMR drive took nearly 230 hours to perform an identical task.

^^ lotsa small writes like in a resliver/rebuild drag the drive to a stop, and the array manager thinks the drives have faulted.

I almost bought two. Then realized I don't need any.

While that sounds more like an edge case, it seems like something ZFS could/should fix.

It's not an edge case. All RAID systems take write failures seriously, not just ZFS.

Nothing about @fly is straight.
