Well to start with for RAID you need to have disks that are all the same size (preferably the same model). I believe Linux supports growing software RAID volumes and I'm sure someone will correct me if it doesn't. Personally I'd go out and buy a 4 device SATA-RAID controller and 4 250GB drives that will give you 750GB of storage and fewer headaches since the RAID array will be seen as any other scsi disk and the card will do the thinking so you won't take a CPU hit for having RAID.
