Hi guys,
Need some help on this ASAP
I need to get an external HDD for one of the guys at work, who is doing a lot of digital photography off site.
Basically i need to know if USB2 or Firewire would be better, i'm thinking USB2 as it has a higer sustained data transfer rate, but i know next to nothing about firewire.
Help greatly apprecaited guys!
technically, firewire is better at SUSTAINED data. firewire is fairly simple - it does some handshaking at both ends, then pours data down the line. that's compared to usb, which sends little fragments of data, with handshaking for each. this makes firewire superb for high-bandwidth situations (such as scanners or DV cams), pretty poor for packet-type situations (e.g. input devices), and middling (depending on the type of data and disk fragmentation) for disk access.
personally i'd use usb2 for a disk, unless he's transferring 2gb video files at a time
You know they come with both, That what I got!
I'll get one with both USB2 and firewire. That way he can choose which connection works best for him.
He might be keeping some vid files on and watch them on screen, as well as MP3 storage and stuff.
Thanks for the help guys!
Firewire uses less CPU than USB2.0 if I remember rightly. I've just got a USB2.0/Firewire enclosure and a 200GB Maxtor. I'd do some benches for you, only my C: drive is on its last legs and as such the benches would probably be unreliable.
I'll post some in a few days when I get some new kit delivered.

Ordered one of the Maxtor 160gb Firewire/USB2 drives. Think they're called one touch?
either is good
firewire is either 400 or 800mbps depending on version ( i think )?
where as usb 2.0 is 480mbps
so firewire800 is the fastest, then usb2, then original firewire
as already said, firewire has the fastest sustained transfer however id personally go with usb2 as his pc is more likely to have that , saves him forkin out a tenner for a firewire card
but yeah if you can get one with both connections, even better
