Regarding SSDs and TRIM, I apply manually this command once a week: --- Code: ---sudo fstrim -av --- End code --- It searches and takes care of all your partions on SSDs. |

For the external storage file systems, my choice was was between btrfs and ZFS. Red Hat will discontinue further development for btrfs, while SUSE made btrfs their official choice. This, and a few extra gimmicks listed as ZFS features made me commit to ZFS. At first, reading about all ZFS can do, makes it intimidating. Classical disk arrays can be complicated to setup or to operate. On the contrary, ZFS was trivially simple to install, setup, and use: --- Code: ---# install zfs (Ubuntu) sudo apt install zfsutils-linux # create a zfs pool named 'WD8TB' on the disk /dev/sdc, and mount the new pool as /WD8TB sudo zpool create WD8TB /dev/sdc # create a new file system named '2019', it will be visible on the file system as /WD8TB/2019 sudo zfs create WD8TB/2019 --- End code --- That's all. /WD8TB/2019 will be available for use like any other folder on the file system. Creating a pool does not require disk partitioning and formatting. All was ready instantly. After copying the old files from the Windows 10 SSD to the new ZFS pool, I tested to see if I can read the ZFS pool disk on another machine (a Fedora 29). --- Code: ---# scan all disks for ZFS pools (scan will complete instantly) sudo zpool import # from the listed pools, import (mount) the wanted one in the home folder of user 'abcdef' sudo zpool import WD8TB -f -R /home/abcdef/ # export (unmount) the pool 'WD8TB' sudo zpool export WD8TB --- End code --- And it was all working great, and very fast. I'm sold for life to ZFS. ^-^ |

However it is out-of-tree, and as of kernel 5.0, has been explicitly dropped. At home, I set up a 4-disk raidZ6 array using FreeNAS, and it works very well . FreeBSD takes a little getting used to for me. Bummer that RHEL dropped support for btrfs. |

That's not the same thing as dropping support for, uh, something never supported to begin with. |
