Hey, thanks for the heads-up. I was able to snag the last one for that price...
Just kidding.
Seagate & Western Digital are both quality HDs. They switch places as to which is better every so often & sometimes one will produce a lemon.
One thing I would caution you about: any external HD without a metal case or without a fan will fail sooner under hard use than one that doesn't. If it is idle most of the time it is no big whoop, though.
I have not heard anything bad about that drive. I would just suggest that be sure you get Firewire 2 interface if you transfer rate is an issue. It smokes USB 2.0. USB is fine for backups, but I am not happy to work straight off a USB drive that is not flash memory.
