Notebook RAID 0 disks tweaking

Hi!
Do you know if it’s possible to put two 2.5″ IDE disks in a regular notebook?
My AcerTravelmate 370 has a normal PATA ide conector. Could I connect another disk with any special connector?
I would like to make an RAID 0 software array …

I know that some notebook do have already two IDE disks (like Toshiba Qosmio)
Thanks, greetings
Antonio
