I'm currently using Mandrake 9.1 (although I plan to go to 9.2 soon...), and I'm curious if anyone knows if I can create a software RAID array between four hard drives. Two of the drives (36GB) are identical and on SATA, the other two are not identical (one 45, the other 160GB) on different IDE cables. I believe it is RAID 0 what I want...for striping instead of mirroring. I can create equaly sized partitions on each drive if necesary, but only two of the drives are of the same speed.
I've played a bit with hardware raid in windows with my onboard controller, and I believe that you need to have each of the drives (or at least partitions) to be of the same speed and size for the array to be effective. Will that cause me problems with my plan using software raid in linux?
How do you guys think this will work performance wise, and what complications I might run into. Unfortunately, won't be able to test it for at least another week until I can find the time.
Thanks.
