I am buying a New Dell E520 computer with the following configuration: 1-Intel Core 2 E6320 duo Processor( 4MB L2 cache, 1.86GHZ, 1066FSB) 2-XP Home OS. 3-2GB memory. 4-250GB Serial ATA HD(7200RPM) 5-Dual DVD drives. 6-256MB Video Card. 7-I will be using it for encoding, Burning DVDs. I am going to add a second HD. I am considering the Seagate Barracuda 7200.10 (Perpendicular Recording) ST3500630AS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive. What are your thoughts on this and is there anything else that I should consider? Thanks in advance!!
