most mp3 players can't host an external hard drive. i assume you want a 2.5" drive enclosure that has mp3 capabilities and i don't know of any.
here's a usb-on-the-go enclosure that can read files from your player.
here's another that is an mp3 player but needs a 1.8" drives:
i think 1.8" hard drives top out around 60gb:
So I've been reading up on usb host capable mp3 players. The one question I can't seem to get an answer to is this:
Can I hook up a usb host capable mp3 player to a usb harddrive and stream mp3's off of it?
Or can you only transfer files with usb host instead of streaming? What I'd like to do is get the cheapest used usb host capable mp3 player and buy a usb enclosure and get a 100gb 3.5 inch harddrive and hook them up. Then I could just dump tons of mp3s at high quality on the harddrive and never have to rotate songs again - except to add new music I buy of course.
If anyone can provide insight on to whether or not usb host (or usb on-the-go) capable mp3 players can stream mp3's off of a usb harddrive in addition to doing file transfers I'd appreciate it. Thanks.
