NAND flash read performance?

Does anyone have any figures for the read performance of the NAND flash controller, when used with 32 bit error correction? I am interested in the added latency of the error correction, including any software overhead (in plain English, how much does it take to do the error correction on a block of memory).

Hello Zoltan,

On the Vybrid Tower module, we have not yet collected NAND performance statistics, with/without ECC. We only have Rev. E hardware on hand at this moment, our Rev. G is currently unavailable for testing purposes. Once it returns, we can put together some test figures as they apply to the VF6xx Tower module.

Regards,

See: VF6xxx NFC (NAND) module clocking, where I give some numbers and code to improve it.
