what is RAID

hmmm no idea bro

RAID = Redundent Array of Independent (or Inexpesive) Disks.

You need to have two or more hard drives to setup RAID, and also a RAID supported motherboard or a PCI card. There are a lot of modes of RAID, but for a desktop user, RAID-0, RAID-1, RAID-0+1, RAID-1+0 are the more applicable ones.

RAID-0 is not actually RAID because it doesn't have that "redundancy" part. This is also called striping. One half of data is on one volume and the other part on the other volume. This mode is for boosting speed rather than having redundancy. If one drive fails, you lose all the data (the part on the other volume as well, because they are not recoverable).

RAID-1 is having the same thing on two volumes, so that if one drive fails, other drive can keep the system running. This is called mirroring, for obvious reasons.

RAID-0+1 is having two RAID-1 sets of RAID-0 volumes. It's like mirroring a RAID-0 set.

RAID-1+0 is the other way round.

If you motherboard supports RAID, it will have a separate manual for that. Refer to that, to build your RAID setup. It's always better to have identical drives in a RAID setup, so that the performance and size are not bottlenecked by slowness and smallness of one drive.

so whats da importency of dis??? any advantages??

RAID-0 = Theoretically can double the speed of file read/write speed. Practically upto 60-70% increase can be expected, but not always.

RAID-1 = Theoretically and practically can double the safety of data from hard drive crashes.

One more advantage with RAID on serial ATA (SATA) is you can run two hard disk drives on mirror stripe basis, Keep the same data on both hard disks. if one disk goes off the mirror will boot the system without no trouble and you will be able to recover all your data.

SATA,SCSI, ATA need special drivers(comes with the mobo disk) to get them up and runing on Windows and MS-DOS, bit complicate if you are not an expert.

Good old IDE drives are bit slower but very easy to configure while installing OS. they are just simply plug and play.

Didn't I say that in my first post?

Good for server pc's.

RAID-0 is good for desktops. Others are good for Servers.

oh i seee. thaks

Ha ha!

This topic is not for me! I don't anything bout these kinda THINGS!

Then why post?

You need 2 or more hard drives!!!
