Im looking for a good affordable external harddrive for DJing. My buddies use Seagate Freeagent Go Firewire 800, are there anything thats comparable to this or do you guys have any recommendation? id prefer firewire over usb 2.0 because i only have 2 USB port, i need 1 for serato and 1 for LED light to display my mixer. Port powered hdd with 7200rpm would be best desired. thanks!
