Hi, I have a small 12-bay SuperMicro server I'm using as a local NAS, with FreeNAS/ZFS. Each drive is a 12TB HDD. I'm in the process of moving it to Linux - and I thought this might be a good chance to try out BTRFS again =). (I'd previously tried BTRFS many years a go, and hit some issues - it's possible this may have been made worse by my inexperience with BTRFS at the time - e.g. https://www.spinics.net/lists/linux-btrfs/msg04240.html) Anyhow - currently the server has a 750GB Intel Optane drive, that we're using as a ZLOG/SIL drive: https://www.ixsystems.com/community/threads/how-best-to-use-960gb-optane-in-freenas-build.75798/#post-527264 My question is - what's the equivalent in BTRFS-land? Or what is the best way to use an ultra-fast Intel Optane drive to accelerate reads/writes on a BTRFS array? Thanks, Victor
