My photographs are starting to take up a fair amount of space and it's time to start looking for a BIG drive to archive my files. I've always been a big fan of WD and have used them exclusively but I'm open to something new. They don't have to be the fastest in the world since I will just be inserting them into a hot swap docking station (eSATA) and running backups in my off hours. They will be used for nothing more than security backups. I will keep one here and one offsite.
