You can use any 3.5-inch (the standard size for internal desktop computer drives) parallel ATA drive. My favorite brand is Seagate, as they tend to be fast, quiet, very high quality, and they come with a *5 year warranty* standard. If you are looking for a 300GB drive, here is an excellent deal on one: Seagate Barracuda 7200.8 ST3300831A 300GB Ultra ATA/100 7200RPM Hard Drive w/8MB Buffer with Free 2nd Day shipping $189 http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=101572 Seagate also has a 400GB drive available.
