Transportable HDD recommendations or warnings

[Ted Roche]

I've got a client who would like to image his half-dozen workstations  
and store the images off-site as part of a disaster recovery plan.

We're planning on using Knoppix and partimage to snapshot the machines,

The workstations are run-of-the-mill Dell Dimensions, fairly new, so  
USB 2.0 should be acceptable.

Guesstimating ~ 5 - 10 Gb per workstation, so most medium capacity  
HDDs should be sufficient. Two separate HDDs for odd- and even-month  
backups could be used for redundancy and avoiding single-point-of- 
failure. (There is already a separate backup system in place for day- 
to-day operational data and documents).

I see the local big boxes have regular promotions for Western  
Digitals, Seagates, Maxtors and SimpleTechs.  Any recommendations  
pro- or con- or are these pretty much commodity items?
