The USB HDD Dock we saw a few months ago just got a USB hub upgrade. Not only does it still take 2.5-inch and 3.5-inch SATA drives in the top like a Famicom cartridge, there's an added 4-port USB hub on the front. Because if you're going to take up one of your machine's precious USB ports for something, it's even better when that something gives you 3 extra ports in return. [Brando]
As much as people would like to discount Firewire, for people who like to clone their HD's when upgrading capacity, or simply to create backups, Firewire is still superior to USB. It's not something I'd care to use on every single doodad I own, but for external storage, it's the only way to go for me, not to mention it's the only way to go if you want to boot off of external equipment (can't do this with USB).
@Lizard_King: "If it is so ubiquitous, what happened to the firewire iPod?"
The iPod's internal hard drive is a slowpoke 4,200 RPM drive with a very small data transfer rate. Even if every computer on the planet had a FW port, you get absolutely no benefit with Firewire when the bottleneck will still be in the drive.
I wouldn't mind getting one of these, but like a few others, without Firewire, it's not worth my money.
