I have personally had problems playing 1080p from a USB 2.0 external, but in my situation I didn't bother to investigate if the bottleneck was in the USB 2.0 connection, the hard drive, or the computer. Hmmm....I always assumed it was the USB port bottle-necking. I learned something new.

By "bandwidth" i was referring to the speed of the connection between your external and your PC.
There are 3 ways to connect a external hard drive.
1.) USB 2.0 (slowest connection)
2.) USB 3.0 (faster connection)
3.) E-Sata (fastest connection)
Here is a picture of E-sata connector on a laptop --> http://www.connectreviews.com/wp/wp-content/uploads/2008/03/gateway_p171xl_2.jpg
E-Sata is like USB,...except it's only for external hard drives and nothing else. E-Sata will provide you with the fastest connection, but older computers don't support E-Sata. Many externals come with both E-SATA and USB. E-Sata is a little more hassle to set up than USB.
As for a 2.5" or 3.5", it doesn't matter. 3.5" HDD are a little bit cheaper, so i'd go with that.
You can defragment a external just like a internal hard drive.
You can set up a HDMI TV/Monitor to mirror whatever you monitor shows. It's easy to do.
EDIT: As rui-no-onna said above me, go with the "do-it-yourself" route with the external. In addition to the points rui-no-onna made, many prebuilt external come with cheap hard drives with poor performance and high failure rates. If you do it yourself you know what's inside the external, and that it's of high quality.Edited by crimsontears809739 - 10/30/12 at 9:25am
