This has been true for many years, too: http://www.miracleas.com/BAARF/ I personally don't even trust RAID 6. All our servers use three-disk RAID 1 setups, with disks from at least two different manufacturers to prevent against firmware bricking (although this is becoming more and more difficult as the industry consolidates). If (no, scratch that, "when") something goes horribly wrong, I can mount any of the disks as normal, non-RAID volumes. All I need is one disk to work. (If none of the disks are working, the RAID level is irrelevant... ;-) To me, that level of confidence is worth sacrificing quite a bit of performance and capacity. It has saved my bacon at least once. -- Robert L Mathews, Tiger Technologies, http://www.tigertech.net/ -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
