Must the disks be exactly identical? I have two seagate barracuda 7200 rpm 80gb drives. however one model number is st3800013as and the other is st380817as. checking the seagate website says that 800013 is the storage capacity of the first and 80817 is the storage capacity of the second. can i still create an array or no?
 
You can create it, sure. You'll end up at twice the capacity of the smaller drive. You might also be concerned with perf -- a slightly slower drive will drag down the whole array. You might want to consider spanning instead of RAID 0.
 
Ok so when I created the raid 0 setup i lost a physical drive when you double click on a computer. the other drive still remained the same size. i thought raid 0 was supposed to merge the two drives into one single drive?
 
Yep, RAID 0 is supposed to give one logical drive with a larger size. I can't guess what you might have done wrong when setting up the array.
 
You're right, creating a RAID 0 array basically merges your 2 HDD's capacity and uses both hdd's to store information and your computer sees your RAID 0 array as one drive. In laymans terms, it cuts the information in half and stores each half independantly on each respective drive, therefore increasing read, write and access times.

You should have gained the capacity of both drives when you RAID 0'ed them. And you have to have identical drives. Or like mikeblas said, twice the capacity of the smaller drive.
 
Or correctly add both drives to the same array? You'll have to go through your RAID BIOS and figure out what went wrong.
 
I figured it out, I don't know why the windows raid creator didn't do it, but the dos one worked perfectly. the drive, although slightly different, work perfectly together.
