usb drive
New to Apple. I'm sure this has been discussed many times but I don't have the time to search every post. I am required to keep data on a usb drive. Due to regulations I CANNOT have the data on a cloud server. I'm considering a new iPad and need to know if there is anyway to access the usb? I bought an Apple usb dongle but it will only work with photos. I need to access data. Is this even possible or do I need to go with a different OS?
