I'd be interested to know how you pulled up those numbers, but I doubt
that they are valid. Calculating the amount of free space on NAND is a
complicated issue, and even more complicated when UBI comes into play.
And UBIFS provides much more conservative free space readings than
jffs2, which often tells you that there is more space available than
there actually is.
That's not to say there isn't an issue here (there may well be), but
you need to prove this with a test that looks at the quantity of data
that can be stored.
