Rock64 No, because old disk HDD was booting from USB 3.0. I wrote about it before.

1. I used Rock64 with DietPi one year with HDD plug in to USB 3.0. and I bought new SSD
2. Plug in to USB 2 and mount
3. Format SSD
4. Change userdata do SSD from HDD and wait to proces finish.
5. Plug off old disk.
6. System start from USB 2.0
7. ok.
8. When I change new SSD to USB 3.0 system boot from SDCard but can’t find new disc and userdata and I cannot login.
