I am looking for a hub or other device that would allow me to backup camera memory cards using an Android Tablet or Smartphone. I would like to use the Tablet or Smartphone to control data transfer from a SD UHS-II memory card using a USB adapter to a USB portable SSD drive. In order to achieve reasonable speeds, this device should use USB 3 ports.
I have been thinking about a similar solution to backup memory cards while on holiday. I have given up the idea for a number of reasons, the primary reason being that it involves too many parts (card reader, hub, cables, SSD) to carry with me. (Another reason being the current travel situation). In the meanwhile I found the optimal solution for my modest requirements: my Samsung Tab S4 tablet accepts large microSD cards (> 400GB), with the use of a USB-C card reader and Samsung MyFiles I can copy files from the card reader to the internal storage card. Only disadvantage is that the app does not allow already existing files to be skipped, the only option is overwrite. I have been thinking to write an app for this purpose, unfortunately for medical reasons I had to postpone this for a while.
There is an app already (sync-memories ) for this purpose, imho this app belongs in the category "CrapWare" because it only functions for memory cards used in Sony cameras and most of the "documented" features have not been implemented.
Thanks for your comment and suggestion Ernst.
I am not sure that backing up to a Micro SD card would be interesting for me since it will likely be quite slow. I am presently using a portable computer to backup from a Lexar 2000X UHS-II card to an external SSD and it is extremely fast. SInce I already bring a Tablet on trips, it would be nice to leave the portable at home.
I have seen solutions that seem to work by reformatting the SD card to a different file format. However, I suspect that it would impact the R/W speed of the card and I hesitate to go that route.
