2x500GB gives you 500gb in raid 0 instead of 1gb normal as the data is stripped over both drives instead to 1 resulting in faster speeds as your PC can read a bit of data from 2 drives at the same time.
RAID 0 gives you the whole of the array - ie 2x 500gb = 1tb - the data is just split to allow access through both drives simultaneously
RAID 1 gives you half the array - ie 2x 500gb = 500gb - the data is duplicated as a backup
etc etc for the other levels you won't be interested in.
RAID 0 is NOT of significant use in a home PC except in very specific circumstances. Unless you do certain activities dealing with large files (such as video editing) you will rarely be limited by disk transfer speed.
