ThinkComputers.org has posted a review on the Apricorn Ez Bus Portable Backup System 20GB

Everyone needs more storage, especially if you travel a lot with your laptop. We also need security and it is recommended we do regular backups. The new trend seems to be toward USB thumb drives, but the speeds just aren't there yet, and the capacities are great for moving a few documents but not major files and programs. The next choice you then have is to either upgrade your hard drive or get an external hard drive, either choice is not great one. External hard drives are big and bulky for the most part and upgrading a laptops hard drive is usually costly and the technology isn't there yet for large capacities. The same thing partially applies to desktop PCs as well, sometimes a CD or DVD is just not big enough to transfer the data you need, so you have to get a big and bulky external/portable hard drive. Today I have something for review that I found really cool and useful, it is a very small USB powered 2.5 inch hard drive from Apricorn called the Ez Bus.
