Best Clustersize for optimal Read/Write speed?

[Guest astuermer]

Hello

Does anyone have an idea whats the best clustersize for optimal read/write speeds on a MicroSD memorycard?

Depending on the storage in gigabytes I think it has to increase with higher storage.

Currently I am using 4096 clustersize on my 8 GB Class 6 card.

But read/write speeds could be better...

Any chance to improve this?

Kind regards, Andreas
