When I was using my Seagate hard drive connected to the MAC computer, I used the Firewire cable that came with the Seagate drive. It worked fine.
However, I am now using the LaCie 3TB d2 USB 3.0 Thunderbolt Series Hard Drive. I am using the Thunderbolt cable to connect it to my MAC Book Pro Computer. It also is working fine. My LaCie hard drive is backed up to my Seagate drive.
Assuming your hard drive is near your computer, I suggest you use the cable that came with the hard drive. As noted above, I see no reason to spent more money on a different cable.
