Hi I'm going to New York in two weeks for 2 month. Additionally to the MacBook (late 2008, without Firewire) I'll need two 2.5" Drives with each 250GB. One for general Backup and another as photo storage. They should mostly be cheap and with USB and are only used in these holidays (as soon as i'm back at home, my MacBook will again be backuped up with my NAS). I can't order them online because it's a small apartment in queens and most the time, i'll be out. So, does anybody have an idea where I can buy two cheap 2.5" USB drives?
