I currently use 2 USB flash drives, one 64GB which I use for my Wii collection, and one 8GB that holds 5 of my GC games while the rest are stored on my compute. I'm getting tired of swapping flash drives and moving games between them and my computer. I want to get a big enough USB hard drive to hold all of them at once. Something in the 256-512GB range would be perfect for me. Preferably one that isn't too expensive (around $20 or less would be ideal, but I'm willing to go as high as $50.) Any recommendations?
