migrating to RAID configuration...any pitfalls?

Well, I got an Abit AT7 mobo, and I have two identical harddrives, so I'm thinking of doing a performance RAID 0+1 setup. Is it safe to assume I can just load windows no problems, or are there any pitfalls I should be aware of?

The other thing I was wondering, will I also be able to plug in a normal IDE drive to recover all of my data from to the new RAID disks? (i.e., can RAID and IDE run at the same time?)
 
I'm really tired redly 1 as I've been awake for over 24 hours now but I'll try to give you a good answer. I only run with a RAID 0 setup but the principle should be the same in this case...

I run both RAID and IDE at the same time. I have two drives on the two RAID channels ( 1 drive on each channel ) and I have a single IDE HDD on IDE 0 on my Epox 8K3A+. They coexist peacefully on my system. But when I install windows, I have to disconnect the drive from IDE 0 or the RAID drive shows up as drive D:\ on my system (WinXP Pro).

Was that what you were looking for?
 
Well, RAID 0+1 requires 4 drives, not two. RAID 0 and RAID 1 both require two drives, but accomplish totally different things. To achieve RAID 0+1 you would need two drives for the RAID 0 (striping) array and two more drives to complete the RAID 1 (mirroring) array. There are other RAID types that support both striping and mirroring with three drives, but most of them are not supported by onboard RAID solutions.
 
I knew I didn't understand RAID !! 🙂
I'm thinking I'm gonna go for the performance RAID (RAID 0, right?) I've got two WD 8mb cache drives, and I've got a lot of video capture to do, so the speed is important.

thanks

Ooo...PS, still wondering.., will I also be able to plug in a normal IDE drive to recover all of my data from to the new RAID disks? (i.e., can RAID and IDE run at the same time?)
 
I learned in one my recent classes that you can actually set up a RAID 1+0 using just 3 drives. Stripe 2 and mirror with one large drive. Not recommended of course but it is doable. There is also RAID 3 and RAID 5 though most RAID adapters on mobos don't support this at all.

You mean plug in another HD on a non raid channel and copy it over? If so the answer is yes. The new raid setup behaves just like a large HD and can be used in the same way.
 
I boot off of a non RAID drive (a SCSI screamer) and put my data on a RAID 0 array. The only downside to RAID0 is if you lose one drive you lose 100% of the data. But I've run RAID0 for years on my home rigs and never had a loss. Still, I regularly back up the important data.

You could certainly make the RAID array your only disk device and boot from it, but it is a little risky. I like to have a small boot drive (36 gig in my case) and use ghost or drive image to copy it to a partition on the RAID array.
 
my opinion on RAID 0 and drive failures is...hell, if I only had one drive and it failed, I'd still lose all of my data!
 
If you have a drive connected to the regular IDE alongside the RAID, it will be the primary master drive, and therefore the drive letters will start (from C: onwards) from there. If you remove that drive or add other drives on the regular IDE then your drive letters will get messed up. Learned that the hard way :|
