I'm not sure I agree with his conclusion, but it's an interesting point. Essentially he's saying that storage is now so large that you can't rebuild a large RAID 5 with a dead drive, because the rate of unrecoverable random bitflips is such that one or more will likely occur in the rest of the drives, leaving you dead in the water. And thus RAID-6 is necessary for large RAIDs if you actually want to recover. Or, something like tahoe, which is really application-level RAID. -Zandr _______________________________________________ tahoe-dev mailing list [email protected] http://allmydata.org/cgi-bin/mailman/listinfo/tahoe-dev
