Same price... I know which one I am getting.

I would use a DVD disk to make my disks though..I am amazed no one has mentioned this.
A flash drive can corrupt at anytime.
A DVD once written will not corrupt later unless it is scratched or has been written to again.

DVDs aren't half as reliable as you'd think.

When I was the Creative Director for a magazine a few years back, we backed everything up to DVD. Each issue was normally around 5 disks, give or take. Anyway, a year later disaster struck and out server drives crashed and were unrecoverable. So we dived into the DVDs to rescue what we needed only to find that 1 out of 5 DVDs worked - the rest had corroded and couldn't be read.

Admittedly, our office was close to the sea, but you get the idea. I wouldn't trust a DVD beyond 5 years maximum.
