Silver Slim PS2 Hard Drive

I have read on several sites that it is possible to use a usb hard drive on the slim model ps2. I understand that a program similar to HDExtreme is required for use of the usb hard drive, but my question to you folks is, is there a specific hard drive that I should be looking for, or will any usb hard drive work? Also, is there anything else that I would need other than the software and the hard drive to be sucessful with this?

Any HD should work fine. I’ve used the program to play NARC and the game play was very smooth but i was using an older PS2 which i don’t believe has usb 2.0 ports so the cutscene audio was very choppy, it was so choppy i haven’t used the program since. If you haven’t been here you should check it out.
