the microcontroller is usually orders of magnitude slower than the host, so "better" does not apply. offloading parity makes a certain amount of sense, but it becomes nontrivial where you draw the line (if you have a parity engine, it's nice to have a substantial cache. if you have a big cache, you have to add more smarts in managing it -> TCQ -> pretty soon you have a full blown SAN raid controller (and the mediocre performance that implies.) I think it's mainly marketing pressure that drives people away from the wisdom of simple-is-better. > a solution which does not consist of a software-raid managed by the > kernel (I had some trouble with it when one of the two disks (RAID 1) > crashed - all data lost). don't be silly - md raid is used in probably tens of millions of servers and is not flakey. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
