Im looking to buy a externiol hard drive and i was looking and found a Seagate BlackArmor 1TB NAS 110 for 60 dollers on black friday. It is normaly a 220 doller hard drive. All im looking for is somthing to have a back up of all my work. I know 1tb is over kill but hey it's 60 dollers and i think its better to have more space then not enough. Now my question is, is that a good exterionl hard drive for what im looking to do?
