This *alone* is worth the cost of the card. The RAID parity calculations are also done in hardware (not a bunch of CPU xor's.) You'd be surprised how much data a small "slow" processor can move when properly programmed. >These turkeys have micro-code bugs that cause a >variety of problem for which there is no workaround or solution other >than trashing the cards. Exactly what bugs? I've used a number of hardware SCSI RAID cards (none by Adaptec however -- some that are now owned by Adapatec) and all of them work properly -- as long as they aren't physically damaged (I had one with a bad DIMM) --Ricky - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
