You choose a storage device based on the capacity A, that's the primary kind of attribute you would look at and then you would choose it secondly based on the interface it uses. So for instance if you had a 500 gigabyte backup storage device but with a USB 2.0 interface that moves a little bit slower than say FireWire at a sustained speed, you would have the same capacity as a FireWire backup device versus a USB backup device but how fast the, or things come on and go off of that device is going to be a little bit slower. So that's what you have to consider when buying them. Also you want to determine how much you would want to buy. So for instance if you wanted to buy a 120 gigabyte external hard drive versus say a 500 gigabyte hard drive that maybe a film editor would use or something like that might be a little bit more cost effective for you. How do you know what to buy? How large of a capacity to buy? Well that's kind of based on what you do. So if you're a video gamer and you want to backup your saved games which could be all of 1 or 2 megabytes, probably a smaller capacity drive like a 120 would be alright. Most people's music libraries are only maybe 20 or 30 gigabytes at tops so that's just a typical kind of idea, a rough outline of where you want to look. The people that need the larger capacities are the geeks like myself that backup a lot of things like programs and applications and do a lot of archival of pictures or more aptly videos that take up a lot of space. So that's where you kind of want to look. Is there a particular brand that I would endorse? No, they're very much very similarly made. You just don't want to go to too cheap because in the computer world you get what you pay for so there is that. A couple of names that you want to keep in mind when shopping for these would be Western Digital, they are the premier for external hard drives. They're name was sullied a little bit a long time ago with bad hard drive defects but as of late, they've seemed to have corrected that. Maxtor and Seagate, those are the kind of three big dogs. So if you want to look at one, compare those companies together. Just kind of find out which interface you should use, FireWire is better than USB. Make sure your computer has a FireWire port if you buy one. Typically all computers have USB ports. And then also the capacity of what you want to buy. Those are how you would choose different storage devices.
