Help with RAID

I'm setting up an ide raid with 2 80g drives. Since i'm using winxp, I've already converted them over to dynamic disks so i will descent peformance out of them.

however, My question is that i currently have them both on one cable... would this slow it down with both on the same cable? or should i split them up and put each on a diffrent ide cable?

depends what kinda of raid are u doing

Mirror or Srtipe
but most of the time tis good to keep them on the same cable and usaley when u do aney kind of raid the speed will drop a little bit

Its good to keep them on the same cable? Umm, no.

If you want the best performance out of it, you want them on different channels. That way both drives can be accessed at the same time.

And if you want any sort of real performance, you'll ditch the WinXP Software RAID stuff and get a RAID card.

it is hardware raid(onboard), and not software raid. In win xp you have to convert the disks to dynamic disks in order to get any kind of good peformance, its been a winxp bug since it came out. and im doing raid 0(stripe)

So the vote goes for each drive to get it's own channel?

It should be faster if each has its own channel.

If its onboard hardware raid there should be some kind of pre-boot bios-like utility you could use to create the array. Windows should see it as a single disk then.

What Vader said.

If you only have two drives on your RAID controller it makes sense to put them each on their own channel. If you have four drives combined into two arrays, put one drive from each array on one channel.
