Dear all Recently I was planing to order a server with RAID 10 protected.I have inquired some providers and get 2 options about RAID. One is motherboard RAID,it seems to be hardware RAID based on the same motherboard.I guess it will still assume CPU resource.but i am not sure about the actual performance improvement on disk I/O. the other is 3Ware RAID Card.this usually takes $30-50/m more,and it wont assume CPU,and will enhance disk I/O evidently. Some of my friends told me motherboard RAID wont really assume CPU.but i still hang on which to choose.
Any buddy here to give advice? thanks very much
