My 10GB Hard Drive is filling up faster than I'ld like. I don't have USB 2, but I do have an Audigy with a FireWire connection. My PC has a 500 mHz Celeron, 250 MB RAM, with Win XP. I saw an ad from Micro Center for a 120GB FireWire External Hard Drive. The brand name was "AcomData." Would this fit the bill, or should I look for a different brand?
