Help Expanding RAID 4 or 5?

Im in the midst of building a media server that will continually grow as a run out of space, but im not sure what to do.

Currently I wil be starting off with three 300gb HDs and was initially going to go with a RAID 5 setup but then quickly relized that one its really diffucult to add a HD to the array with out starting from scratch but also it locks me in to adding only 300gb HDs.

Now reading on RAID 4 I assume you can add different size HDs and still retain the use off all the HD space, so that if I add a 400gb HD later on down the road, the parity drive will then become the 400gb and Ill have access to the full use of three 300gb hds. And if I upgrade once again lets say another 400gb the RAID-4 array will use all of the space between the three 300gb HDs as well as the new 400gb HD correct? or is this the same senario as the RAID-5 where the array will treat all the HDs as if they were only 300gb HDs?

Im just trying to find a solution where I can have different size HDs that I will continue to add and still maintain a little redundancy like the parity.
