Mini-SD cluster size when formatting can affect performance

Apparently, formatting with a cluster size of 32kb can improve Dingux performance, but isn’t recognised by the native firmware.  Read more here: http://grm.hopto.org:6080/dingoo-a320/hardware-and-modding/, or use the English cheat notes below.

Interesting discussion was formed on zx-spectrum - the forum.
Collective Intelligence in the face of one of the users has revealed an interesting feature of the dinghy. When using a large size so happens that the producer reformats them with a cluster size of 32KB. This makes it possible to achieve some increase in speed, by reading more data at a time.
So.
The experimental Digna with firmware 1.2 flatly refused to work with a card with a cluster size of 32KB. So Dingux worked, everything was read in mode, card reader, but never saw one mp3shka, or ROM.
Decision - to reformat the card with a cluster of 4kb.
Probably will not work and intermediate values, but in any case, do not despair immediately after purchase card, if something suddenly failed to start immediately.
