Re: RAID 1+0 versus RAID 0+1
Follow-up in the RAID 1+0 versus 0+1 discussion. Paul Watson joked that a site had told him RAID10 and RAID01 did not work. Obnoxio The Clown reported a site that suffered creeping data corruption because RAID 5 does not validate parity, and Art S. Kagel agreed. Art said he runs 150 RAID10 arrays of over 2000 drives successfully.
