Yes, ... and I'm trying to analyse how/why that might seem to be the 
case.

As I said: a card may get slower as it gets full, but that's NOT 
something that only happens with FAT.

The point is that where TRIM is supported the slow-down when a card gets 
full will be less, because of the information provided by TRIM. If the 
card supports TRIM but the FAT filesystem driver doesn't, then the 
benefit of TRIM won't be seen if the card is formatted with FAT. In that 
case (but AFAICS *only* in that case) "nospam" may be correct.

However, I doubt the flash controllers in most micro-SD cards (unlike 
big SSDs with e.g. SATA interfaces) typically support TRIM.
