Besides backups, use at least RAID-1 --- disks *will* fail, the only question is when. You could put the partitions that contain variable data, particularly /home, /var and /tmp, onto a volume that is on non-SSD drives and keep everything else mounted read-only as much as possible. In case you have their five year warranty and if you're willing to give your disks out of your hands after you put your data onto them, it probably doesn't matter when they fail. They specify 1.5 million hours MTBF --- if there's anything to that, it should outlast non-SSDs. You could look at btrfs, if that's an option for you, and see what the status of it's support for SSDs is. -- Fedora 18 -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
