|'''Power efficient raid'''|| idea || Data needs to be written to multiple drives; so a single head-crash does not wipe it out. However, it could be staged to disks sequentially, remaining in memory until it has been written on the 2nd (or n'th) drive. The drives could be spun up more rarely, to simply update the file-store. | |'''Power efficient raid'''|| idea || Data needs to be written to multiple drives; so a single head-crash does not wipe it out.

Perhaps it can be done using two or more file systems and unionfs; with the data eventually residing on a spinning disk, but initially being saved on ssd. The spinning disk using btrfs to make a sequence of stable snapshots from changes preserved on the ssd. | |||
Maybe btrfs offers this sort of thing directly? | |||
