It seems SMR is poison to all sorts of workloads having +small files and directories being rewritten (not that drives employing it have sequential speeds that are exactly +stellar either) like what git and git-annex are doing under the hood. I bought an 6TB WD Elements desktop drive recently +(knowingly an SMR unit because non-SMR HDDs are rather expensive here in Finland) as an git-annex archival drive and I was +flabbergasted at how slow it turned out for merely syncing git metadata. I'm on Windows and have to use adjusted-unlocked +branches so there's that but NTFS on Windows is not terribly slow -- maybe not as speedy as Linux filesystems but it caches +metadata rather well, so it's ok. The problem is that while my 4TB Seagate IronWolf non-SMR drive (git-annex) syncs +in a minute or two, my new 6TB takes a minimum of *ten* minutes or so to do that. At this point I have just resigned myself +to the fact that all my future archival drives where I use regular git remotes will be slow as molasses. I'd love to own +big, fast non-SMR enterprise drives but those will be outside my budget for years to come, I'm afraid. :/ +"""]] -- 2.30.2
