Or 2-Box improves the Brains hardware interfacing. Any clue if the IO controller controlling the memory is flash as well?
Hi,
no, its not flash but hardware. At least my module uses an Atmel AT91SAM9261CJ which has the interface for SD cards included. So in that regard there won't be an update unless the really change hardware. However, i think the transfer rate is not crucial. The original card of my module is "only" class 6.
If the transfer rate is too low i would expect interrupted sounds but i never experienced/heard about that. In terms of latency there are obviously other parameters like any kind of access time or whatever. I don't know what it is and even if it doesn't help. Those parameters are usually not available for cards of consumer grade. There are also industrial grade cards with better datasheets but at a much higher price.
So the only thing we can do is try and hope that the vendor doesn't change anything once we found a "good" card. Unfortunately these consumer cards are changed from time to time without any change of the labelling.
Regards, Manfred
PS. The USB interface is 2.0 compatible but only low speed (1.5MBit/s) and full speed (12MBit/s). So this won't be updated too.
