i have a 80 gb and a 40 gb and i want to raid them is there anything specific i should kno before i do so that i didnt allready kno ... can a raid go wrong or anything
If you raid them you get the minimum features of each drive. It would work but you'd likely lose a lot of HD space.
One thing you might try however is setting them up as dynamic disks. Then you could use 40GB of each for a RAID0 setup and use the remaining 40GB on the large drive as a simple partition. Save your space and still get a performance boost. Setting it up would be fairly straight forward as well.
how would i go bout doin that ... and i know i would lose alot of space actually it would be my first raid and i wanted to try it out before i bought matching drives
