Hello,
I want to buy a few HDDs for use as personal home backup. The drives will be set up as standalone (non-RAID) ZFS volumes with the option
I know that most HDDs marketed for desktop are SMR nowadays, and that SMR is known to offer poor performance with ZFS. But does it really matter in my usecase? The complaints I read about it were mostly about server usage, usually involving RAID setups and frequent random writes. Are there significant downsides of using ZFS on SMR drives in a context consisting mostly of large sequential writes and deletions? Is
If CMR drives are a better option, then what kind of drives would better fit the purpose? NAS drives (Seagate IronWolf, WD Red Plus...), CCTV drives (Seagate SkyHawk, WD Purple...)? Datacenter-grade hardware is pricey and probably overkill for redundant storage which is offline most of the time.
