HarcoreWare.net has posted a pretty detailed guide to portable storage. This only covers products up to Q4 of 2004.
Quote from the guide:
“If you’re thinking of a suitable gift for a PC user, a portable storage device should probably be one of the first things on your mind. They are cheap, look neat, and incredibly useful. However there are a few different types to consider, and depending on your needs, one may be more suitable than another.
Today we’re going to look at several portable solutions – from a bulky 3.5″ drive enclosure to the amazing 5GB Seagate Pocket Drive. We also check out Kingston’s super fast Data Traveler Elite USB2 Flash Drive that breaks flash media speed records.”
This is a pretty good guide that covers, pocket hard drives, flash drives and even the larger external hard drives.
