i bought a western digital 120gb drive and i decided that i wanted more storage. i have heard from past that in order to run RAID the hard drive must be the same brand and same size, correct me if im wrong. but is that all that must be the same? (other than them both being sata)
 
They dont have to be, you can raid two different drives of different sizes together (wouldnt use extra space on larger drive), but it would be ideal for them to be the same size with the same read/write speeds.
 
Brand does not really matter, you can mix them if you want.

Size does though, you should always use the same size drive.
 
It doesn't really matter, if you use 2 different size drives, the array will only be twice as large as the smaller drive (RAID 0).

which is a total waste...so might as well just get the same size drive
 
Or you can just add the second drive as a seperate volume, unless you really want it all on one drive letter. As far as getting it all on one drive letter you can also do JBOD (Just a Bunch Of Disks) to simply join the disks together instead of striping (depending on your raid hardware/software.)
 
For storage, you dont want to raid-0 drives - if one drive dies, or data gets corrupted, you lose the data on both drives. Raid-1 (mirroring) wont yield more storage, but with it if you lose a drive, no data is lost.
Raid-5 is good for storage, but you need at least three drives for it. Capacity of the array is Size of drives used*number of drives-capacity of one drive (eg 4 300GB drives will yield 900GB capacity). With raid-5 if one drive dies, all your data will remain online and accessable. You wont lose data as long as you replace the dead drive before another one happens to drive.
In your situation I would just get a second storage drive, and if you really want them on one drive letter, either use the windows dynamic disk to make a spanned volume or make a JBOD if your controller allows for it.
