Hi Alan,

For playback you should be fine with any sort flash drive, stick or hdd. From what I can tell, recent drives have more then enough bandwidth to deal with our audio playback requirements. So in my experience, once you succeeded to copy your content, you run a thorough test drive (which includes low frequency vibrations, and other shocks that might occur in live situation…. Especially for hdd that have safety features and park their heads for protection from shocks!) and you should be more then fine.
For recording I always fresh format on the device and simply let it record once thru the entire disk.
Never failed me so far on at least a dozen different drives of all sorts and makes
