Writing frequently to NAND - wearing, caching?

[Martin Egholm Nielsen]

Hi there,

I have an application which may need to write states frequently to my 
nand-fs in order to have these states in case of powerdown.
But I'm a bit concerned about wearing the nand if I write to frequently.

So, if I only need to write, say, 100 bytes every second, how often will 
this actually be flushed to the nand?
Is there a maximum commit/flush frequency built in the driver? Or can 
this be configured?
I know this is a very diffuse question, but hopefully you get my drift.

BR,
