I can be without computer for the number of days it takes to get a new disk, then spend 2h installing Linux and anything up to X to configure it again the way I had it. Or I can take a slightly older disk from a previous computer, or buy another smaller disk, put it in as well, and remain mostly operational (and fully for email etc) all the way. There's just no comparison. Mount the non-raided disk partitions of the two disks as /data and /biggerdata, use one for your collections and the other for on-disk ISOs of your install media or latest backups. Raid doesn't do away with the need for backups, but the hassles it saves are enormous. A fortnight ago I ran badblocks etc and the works on one disk while keeping on working on the other disk. No problems, just a few reallocated sectors, so hot-add it again. Zero downtime.
