I did it I guess because of the ease to use it and test games,and I already had SM 3.8 coder and USbextreme. I have about 40 games or so on my 350GB USB drive. Sometimes the movies are choppy and slow, but the game plays fine. I only keep the games on that play, and use it on my V5, V7 and my V14 slim. Then when the kids want to play one they can use the usb drive and I use the other. Definitely a hd is better(more compatible with games)or modchip the ps2 is better yet.
