note that if you are interested in write performance (as you might be :) ), it might actually be cheaper... to go with raid10. it's all your decision, and i won't rehash arguments here - but http://www.baarf.com/ has some arguments :) > Does anyone have any thoughts or recommendations > for specific devices? have you already decided for hardware or software raid ? lately i'm mostly leaning towards software raid. some of the benefits are generic maintenance, individual disk access for smart monitoring (which also is supported by some hw raid controllers and latest smartmontools), much easier and safer recovery in case box goes down (you don't need another identical hw raid controller) - and there probably are more :) cpu overhead with raid5 for a backup machine with a modern cpu would not be significant (actually, my backup machines mostly have idle cpus), and probably non-existent with raid1[0] i was reading a page some time ago which summed up linux software raid benefits and drawbacks quite extensively (i think one of the developers wrote that), but i can't find it right now :) > Mike -- Rich ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
