Some great ideas there. Agree about complexity - its usually a sign of something dodgy being hidden. Perhaps a flash raid 1 device would suffice?

  The scary thing is that you lose the whole device, and flash seems more fragile this way that disks are. Perhaps we just understand disk failure modes better, and are more comfortable with them.

    Good point. Mechanical disks usually start exhibiting warning signs when failing (the disk in my T61 started clicking about a month ago is being replaced tomorrow). I'm not sure I'll get away with that in the Samsung 840 that is going in it instead. (yes I do backups and rsync hourly before anyone slates me for working on a cranky machine).

    > Perhaps we just understand disk failure modes better, and are more comfortable with them. In some ways, predictability is an issue too. SSD typically fail after a relatively set number of write cycles, which doesn't seem too much of an issue until you try to put them into a RAID5 array. I've heard stories of a couple of people trying this, and having multiple drives all fail within hours of each other (usually during the array rebuild). It's something I'd never have thought about had I not been prompted.
