I don't understand few things about RAID 0. Does it help only when you have more then 1 hard drive? i understand that threr are few disks in a hard drive. I have 30Gb Maxtor Diamond 7200rpm and ata/100, my A7V doesn't support RAID 0. Will performance and speed of my hard drive, loadings and avings be faster? Is there a PCI RAID 0 card I can buy?
