Yes, you can use IDE. I put a Promise Ultra100 TX2 controller into a server
that I built. Also, a friend at working is using a Promise controller on
his home system which is hosting a Web site. I don't remember what I paid
for the controller, but it was in the $100 to $150.
Here are some Web sites that may be of interest to the readership. They are
reviews, comparison and mfr sites,

compare: http://www4.tomshardware.com/storage/20011023/raid-05.html
review: http://www.hardwarecentral.com/hardwarecentral/news/1349/1/
A note about the compare URL. LSI Logic bought up the AMI RAID controllers.
My from the little shopping that I did in the local area (Redmond, WA) the
Promise controller seemed to be the one that was carried.
Hope this helps.

Will RAID work on IDE drives? I thought it was for SCSI only?

RI>Just a couple of comments, although the documentation for any RAID
RI>controller should point a lot of this out.
RI>1) RAID stands for Redundant Array of Individual Disks. There are
several
RI> different types of RAID schemes, the most common being the following
RI> RAID 0 - striping data across 2 or more disks
RI> RAID 1 - mirroring data across 2 disks
RI> RAID 5 - striping data across disks, with parity (min of 3
disks).
RI> I could go on here, but realistically, this is what you tend to run
RI> into the most on the market place.
RI>2) For the home user the cheapest, most hassle-free would probably
RI> be RAID 1, or mirroring. Cheap - because you only need one more disk
RI> to do it. Hassle-free - because if you had to you can "break" a
"mirror
RI> set" and use the surviving disk alone. If you replace a disk that
breaks
RI> the controller will "rebuild" the mirror set when the new disks is put
RI>in.
RI> This can be time consuming (hours if you are also using your machine),
RI>but
RI> at least in the end you have "protected" data again.
RI>3) STAY AWAY from RAID 0. This is simple striping. Think of it this
way,
RI> your two 6GB drives are combined into a single 12GB drive (as far as
your
RI> operating system is concerned), but the controller "stripes" the data
RI> across the two surfaces in chunks of, let's say, 32K bytes. If you
lose
RI> one drive you have a lost ALL your data. Striping is most often done
for
RI> (READ) performance.
RI>4) Some good info can be found at:
RI>http://www.compinfo-center.com/stor/raid.htm.
RI>I should also mention that some people would argue with me that RAID 5 is
a
RI>better way to go, since you get good READ speeds and slightly more
storage
RI>for the $buck. And their arguments are very valid in a lot of
RI>circumstances.
RI>However, for the home user RAID 1 is better because even if the
controller
RI>were to break there is at least a chance that the one of the disks can
just
RI>be put on the default controller of the mother board.
RI>Cheers,
