Hi,

we have an update protocol that normally relies on data being received while the previous block is written to flash.

My 2c: Overlapping data transfer with flash erase/write operations can be beneficial as it can reduce the programming time substantially. (Erase is less beneficial than write since erases don't happen as often and take a relatively long time, so the overlap optimization savings is a smaller percentage of the total erase time - Amdahl's Law.)

By the way, what sort of benefit do you see? What is your load time with and without the non-blocking changes?
