Hello,
Recently I've bought 6Tb WD drive (WD60EZAZ) which appeared to be a DM-SMR drive. I'm not complaining as this 6Tb drive cost me less than regular 4Tb drives so I expected complications. This drive going to be used for Video/Music/Photo storage and occasional gaming. My system/home drive will remain SSD, but now I'm digging for information on how to use SMR drive in its optimal performance.
Unfortunately all the information I could find is rather old (~2015) and related to kernel versions 3.X and 4.X while I'm using Manjaro with 5.6 kernel, plus there is also a big mess in SMR world as some of the solutions offered for Host-Aware SMR drives and I'm not sure if they can be transparently applied to DM-SMR, hence I have following questions, and would appreciate any help:
What Linux FS would be optimal for DM-SMR? My gut feeling tells me that CoW approach would work the best, but I don't actually need any bells and whistles provided by ZFS or BtrFS in exchange of performance penalty, and have quite unpleasant experience with XFS caused me data loss due to sudden power cut.
Does anyone use DM-SMR drive with plain ext4 and what are your mounting options? Did you use any FS optimizations when formatting FS?
From my understanding DM-SMR has been created as plug and use devices by design, so end user shouldn't even notice that drive is anyhow different from traditional CMR/PMR. How far is my understanding from actual users experience? Does it really matter what FS you have chosen for the DM-SMR drive in 2020?
I believe this topic might be interested for many of us, as DM-SMR become more and more common thing in big capacity hard drives world nowadays.
