But doesn't the CP data (sorry, UBIUBI data :) need to have one

CP data is still linearly scaled to device size (with a very small
multiplier)?


It's UBIVIS data. :D

The size of the checkpoint depends on the number of free/used PEBs.
But in most cases the checkpoints fits into one or two PEBs.
Because larger devices have larger erase blocks...
