google: mtdl raid6 intel

Triple parity ala ZFS? sheesh. Reminds me of a pissy exchange I had
years ago with someone that was insisting we would see 128 bit CPUs.

The whole idea of multiple drive failures is not a fun discussion either. Imagine
a data center with 3000 drives (BTDT) and it loses a drive every few weeks
(maybe once every 2 months) now imagine it loses a drive in a RAID6 array
and THEN loses another drive during rebuild and THEN hits a UBE during that
rebuild.

Sure.. possible, once every 100 years (see above).

If the data is that stinking important it would be in-sync in at least 2 dispersed
datacenters.

I’m not seeing RAID protection beyond RAID6 having much uptick. My opinion.
