I think in Linux, if you're using mdadm there is the ability to specify a write journal; all data (i.e. blocks+parity) gets written to the journal first, and then gets cleaned up after everything gets completed successfully, and the journal is replayed after a power failure. Mind you, for that to work well you'd want a victim SSD with a write speed at least that of the array... |
