Yep - we are recommending to disable zeroing as soon as chunksize >512K.

But for 'security' reason the option it's up to users to select what fits the needs in the best way - there is no  'one solution fits them all' in this case.

Sure, but again: if writing a block larger than the underlying chunk, zeroing can (and should) skipped. Yet I seem to remember that the new block is zeroed in any case, even if it is going to be rewritten entirely.

Do I remember wrongly?
