I'm looking for a 64gb USB drive that works with the N810. I am considering either the Patriot Magnum 64gb or Kingston 64GB DataTraveler 150 Flash Drive (both around $115 right now). Can anyone confirm that either of these work or one from the same range but smaller (32gb, 16gb etc)? I'm planning to use with Canola - anyone have any issues with a flashdrive connected with OTG full of MP3's? Cheers
