Dear Sirs.
I'm thinking of purchasing a card as mentioned above. If installed, does the disks have to be identical? (same speed, cache, brand) ? If not, does the technology optimize the R/W according to the specifications of the disks ?

Happy for any reply !!!

Hi Brainwashed!

In direct answer to your question, if you're deploying RAID 0 (or RAID Zero), the disks don't need to be the same size, nor do they need to be the same cache size or from the same manufacturer, although you will take a performance hit if there is too much disparity. The only real reason to deplot Raid 0 would be if you had two or more small SCSI hard drives, such as maybe 1.2G to 2G and you wanted to couple them and have them appear as one large drive. Other than this, there's no benefit to Raid 0, and there is no mirroring or redundancy. The URL below will give you a pretty decent handle on Raid implementation.

Didn't know Win98 supported any type of RAID. I guess I'm wrong.

Adam, directly, it doesn't, but Raid0 is a software induced striping.
