I recently got a Lacie PocketDrive, which has both USB 2.0 and firewire 400 connections. Is there any particular reason to choose one over the other?
Thanks!

FireWire is usually a bit faster, because while USB 2 has a higher raw data rate, its data payload is lower than FireWire's.

Firewire 400 using an enclosure with an Oxford 911 chipset is the only way to go (unless you go Firewire 800).

Firewire drives are boot-able on most modern Macs (those that contain built-in firewire capabilities.
Being able to boot from your external can be very handy, provide you placed an OS and a few recovery tools for emergencies on the external drive.

Firewire 400 can also provide enough power to run the drive, without a separate power connector (for 2.5" drives like the PocketDrive). I believe you need a power adapter for USB 2.0, which IMO significantly limits portability because you have to lug it around.

Any Mac that can boot from FireWire can also boot from USB.
Note that not all Macs with built-in FireWire can boot from it -- only Macs with AGP graphics can boot from FireWire and USB (and enter into Target Disk Mode).

Right... about the boot from Firewire drive...
When you use your iBook / Powerbook to boot from a firewire drive, that is not AC powered, I have found significant battery suckage.
I however do have a 60 GB Lacie, 7,200 rpm, firewire 400 drive. It has an AC adapter... and boots great, very very fast.
I have owned a few other LaCie products, and definetly suggest that as the company to with for firewire products
