What is "raid function" ???

[Ravioli]

Recently discovered i had a Raid Function in my bios, what does this mean? What does it do? I tried looking it up on wikipedia etc but the information is to difficult to understand.

It means you can sort of merge different hard disk into one logical unit. Useful if you own a couple of Raptor disks or lots of small ones. It also has a few other advantages that I don't remember right now.

Lot of workstations and severs use them. Most desktops don't.

RAID 0 - makes 2 hard drives look like 1 bigger drive. It can be faster for read/writing to the disk because the PC can do so to both at the same time. But the higher latency can sometimes make it go slower. Depends on what applications you run. It really shines for workstation/server stuff.

RAID 1 - writes the same data to both hard drives. They are mirrored drives. It's to make sure the up-time of the PC is longer. (not a backup)

Raid 0 is faster then Raid1 because it copies half of all your file to each drive,but if one drive dies then your screwed.

With Raid 1 though all files are mirrored or copied exactly to a second drive like asus said,but it may not be as fast. if one drive dies then you wont lose all of your files because it will be on one or the other drive that is still functioning.

Anandtech just had a write-up on RAID recently.
This article cautions desktop use of RAID.
