What does "RAID" mean

[Guest]

I keep seeing "RAID" attached to MB names, especially ABIT.

Besides "raiding" your wallet what is this "RAID" thing?

Redundant Array of Independant Disks. Its used for fault tolerance. Raid 1-5 is supported by NT which includes mirroring, Duplexing, Striping and Striping with Parity.

Sorry to be picky...
It's Redundant Array of <b>Inexpensive</b> Disks... (or is it drives!)

 

[Geeba]

No, it's disks....
Generally it's using 2 or more drives as one logical drive. This speeds up the (logical) drive (RAID 0), or provides fault tolerance, by keeping 2 copies of the data on 2 seperate disks (RAID 1). That's the RAID on the Abit and so on. There are many other different forms of RAID. When are we going to get RAID 5 on an IDE controller???

Raid 5 = Poor Performance!

sorry wrong agian not "inexpensive" independant is correct
it was original available for scsi hd only.
and they dont come close to inexpensive.


who is more foolish...
the fool, or the fool that takes his advice?

It's inexpensive disks.

When it was created, SCSI Disks were less expensive than IDE disks.. That's why they called it

Redundant array of inexpensive disks.... Now we could say it's not true anymore, but the right name is Inexpensive.

Whether its Independant or Inexpensive really doesn't matter. I have heard it called both.

It still does the same thing. ALso Hardware based RAID 5 rocks.

Agreed. Software raid 5 sucks but a good raid adapter and nice scsi disks can be quite performant and quite secure.. ( Still need to make tape backup just in case 2 disks crash at the same time ).
