I would recommend Samsung Spinpoint F3 drives, which have slightly higher ratings than the WD1002FAEX on newegg, and are the fastest 1TB drive for streaming reads. They're listed as $52.99+shipping ($49.65 for 10 drives) at CompUPlus.com ( http://www.compuplus.com/Drives-and-storage/Samsung-1TB-Spinpoint-F3-7200RPM-1138634.html), and If you contact a sales person, there's a discount for ordering more than 10.
