I am using an external USB drive for video. Is it possible to increase the speed of the drive to make rendering/copying/, etc., faster? When I have a couple of applications writing to the drive, and I open up the hard drive in the Finder, it takes awhile to load the files/folders.

There's not much you can do to "optimize" your transfer rate. OS X should be maxing out your USB connection as it is.

If that's not fast enough you might want to look at a USB 3 drive (if you're not already using one) or a Firewire drive which will give you better throughput. FireWire enclosures are a bit more expensive but they're worth it if you need higher throughput (for say, video rendering, etc).

Yeah...I am using a USB 2.0 drive. Though reading about the Firewire drive reminds me that I think I have an extra one. Thanks so much! – daviesgeek Jul 28 '11 at 16:11
Consider taking the drive out of its USB enclosure and buying a firewire enclosure for it. – Richard Feb 26 '12 at 11:34
