Big leap for hard drive capacities: 32 TB HAMR drives due soon, 40tb on horizon
As my NAS expands, I get more and more cold data. Meanwhile large SSD's are getting cheap-ish (even TLC variants).<p>Are there any good options right now for multi-tiered storage for the home lab?<p>LVM has writeback cache as an option, but I couldn't quite figure out how reliable that is, found some old posts with disturbing issues but not a lot of recent talk. Would also need to run ZFS on top of it for the ZFS features I rely on like snapshots and such, so feels like a Jenga tower solution.<p>I know Ceph has this option, but Ceph performance is abysmal for small installations from what I could benchmark.<p>Bcachefs looks like it'll be a winner, but it's still WIP so won't trust it with my precious data quite yet I think.
