This month i bought sandisk ultra 128 GB dual drive USB type C which can be used easily on your pc or labtop using its usb port and can be pluged directly to your Mi 9 type C port. I use it for backing up all my phone data. It is small and light. And very fast. I bought it for about 20 US dollars .
