What I did was convert my 2x1TB HDDs (rescued from a dead NAS) to a BTRFS RAID1 array and attach them via a USB3 port for use as backup (using BorgBackup, which dedupes and compresses). I installed a single 2TB SSD (on a SATA3 port) for active use, i.e. /root, /home, /boot etc., also under BTRFS but with no RAID. My workload is nothing special, so YMMV, but I find the throughput of the SSD so dramatically better than an HDD that I don't care that it's not striped. poc _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
