What I was wanting to do was put all of my big media (ex. Game Review Videos, Music Videos, MP3s) on the external to take the load off of the internal.
One thing came to mind that might be a problem. Would I be overloading my processor by making it read from two hard drives?
Uh, no. Why don't u just get a new internal hard drive? They're faster, bigger (in storage space) and cheaper, a lot cheaper. Also, no, having two hard drives won't even come close to overloading your processor. For one thing, processors don't over load, they just lagg if you have to many programs running. If you have a slow processor, and running a high end program or game, it won't "over load", it'll just run slow, and do as much work as it can.

Internal is neither faster nor bigger, (unless the external you're looking at is a 2.5" drive), they're just simpler because you don't need an external power supply and casing. If you're computer is old enough to not have any USB 2.0 connections though, you definitely want an internal drive. An external drive going through a USB 1.1 connection would be excruciatingly slow.
Size is whatever you want to buy, but I reccomend staying away from the 750GB drives, as they're not really very reliable yet. Further, you're going to want a drive that uses an IDE interface of some sort, since I figure your system's too old to have any SATA connections, and I strongly doubt you have any SCSI hardware in there.
Reading from the drives is the job of the motherboard and the harddrive controllers, not so much the processor. If the processor and computer is over 6-8 years old though, then you may as well just get a new system.
I'm going to stick with getting an external. In my case, it's easier.
