SATA vs Raid
Hello can anyone explain to me the difference between SATA and Raid or are they one of the same?
I recently bought a DVD burner that has a SATA interface. I didn't have a SATA power connect on my mother board so i bought a PCI SATA card and it works really well.
I was planning to buy a secondary hard drive which also has a SATA interface but i was reading some reviews that some SATA cards may not be Raid can anyone help me on this. The PCI card has 2 two ports one which is in use for the DVD burner the other is free. The card is a Silicon Image card or something like that
Thanks for any info

SATA is an alternative to SCSI and IDE. Its a method of connecting storage devices to your system. SATA is faster than IDE. SCSI is rarely found in desktops.
RAID is a way of combining multiple disks into one for performance or reliabuility reasons. If all you want to do is add a second hard drive to your system, you do NOT need RAID. Your exisiting SATA card is fine.

masterask,
I could be wrong, but SATA is just another way for hard drives to transfer data while RAID is a system by which you can mirror hard drives or treat multiple hard drives as one.
