What is RAID?

Call me stupid but I keep hearing that the 8890 will have RAID.

Only problem is I have no idea what it is.

So if I upgrade my mobo from 8887 to 8890, do I get that as well?

It's a means for providing fault tolerance

Webopedia.com
Short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers

There are number of different RAID levels. The three most common are 0, 3, and 5:
  • Level 0: Provides data striping (spreading out blocks of each file across multiple disks) but no redundancy. This improves performance but does not deliver fault tolerance.
  • Level 1: Provides disk mirroring.
  • Level 3: Same as Level 0, but also reserves one dedicated disk for error correction data. It provides good performance and some level of fault tolerance.
  • Level 5: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance

So, what are the benefits of RAID to the average laptop user--ie one who does not play with network servers or software design?

Pretty much minimal, if you're not planning on doing huge graphic manipulations or video compressions. If your main objective is to play games and surf and type, you're not going to get much out of RAID.

A raid is also when a bunch of guys attack an enemy position. Using speed, surprise, and violence of action, a raid can be very effective.

Mostly true, though RAID 0 does significantly increase hard drive performance for anything that accesses the hard drive. Games that do periodic loading while playing run much smoother.

Also RAID 1 would provide good fault tolerance, so no backups would ever be necessary. It's not a daily benefit, but it so would be a nice thing it one of your drives should happen to fail some day. Other RAID levels would be great too, but IDE is primarily limited to 0,1, and 0+1 on most systems.

RAID 2, 4, 7, 53 are other less common configurations.

kpk02 is precisely right, but there is an added drawback to raid 0 (striping) if you lose one of your drives in a raid 0 array....you lose all of your data

Now for my question. I had to send my 9890 back for repair and told them to install a second H.D. So now, how do I get Raid 1 going?

You know instead of resurrecting a 3 year old thread why not just start a new one?
