It depends on the model you buy. I've seen models that hold 1 TB (TB is a Terabyte, which is a 1000 gigabytes). You can easily find other models that hold about 800 GB, especially at Future Shop. Obviously, the models that hold more will cost more, which adds up to about $120.00 if on sale (I saw a 1 TB model at Future Shop that costs this on Boxing Day, meaning it would probably be like $160.00-$200.00 without a sale).
An external hard drive storage capacity is limited only by the latest technology. You can even get an external hard drive enclosure for an internal drive and connect it to your computer via USB.
I recently saw a 16TB (terabyte) external hard drive storage array on one particular online shopping website. It sells for nearly $7,000. That's probably more than you need (or want to pay).
The largest single external hard drive I've seen for sale is 2TB, although by the time you read this there will probably be larger capacity drives on the market. As I said, this is limited only by the latest technology.
1,024 megabytes = 1 gigabyte

The typical ones are around 120GB and 320GB.

A TB external hard drive means that the storage capacity of the particular hard drive is equal to 1 TB or terabyte. A terabyte is equal to 1,000 gigabytes or GB.
No, resolution refers to the video capacity of a monitor. The capacity of a storage drive is called storage capacity, not resolution.
There are two types of drives, either internal or external. An external drive would only offer external storage. It is kept internally on the external drive but that is all.

If your DVR has an eSATA or Firewire port on the back, it is sometimes possible to attach a regular external hard drive for computers to it to expand the storage space. After formatting the external hard drive for the DVR, your DVR is most likely to restart recording TV shows into either its internal hard drive or external that you attached depending on which has more available storage space. Consult with your DVR's owner's manual. Note that you will not be able to take out the recordings from the external hard drive using a computer as the external hard drive has to be formatted FOR the DVR in such a way that the computer cannot see / access it.
