I have the 500 GB WD USB Drive here and it has Biab, RB & PT on it. It works very well with Biab, along with generating Real Tracks fast. Mine has both a USB and an AC Power Plug. I use it with my laptop and it has performed flawlessly so far.

I like having my music software located on the USB drive. You just have to make sure you update files to the correct drive during set up. I leave mine plugged in and don't mess with it.

I would highly recommend it for use with PG Music's software.
