Hello to everyone, my iMac's SSD (start up volume) is almost full. My 16 GB iPad is in the same situation. I'd like a device (preferred SSD + Wi-Fi) with enough capacity to keep my iMac's and iPad's files. Is there any product which I can use it as my extra startup volume for iMac and to connect my iPad also for save my iPad's files ? Or I want too much ? Any suggestions ?
