Hello,
What is the max latency you can choose when using defer-write "native"?

There is no limit and you even can choose "INFINITE", but usually this is useless because long latency will make the cache which has a limited space full of deferred write-data soon. When cache is full, "Urgent Writes" will be triggered, flushing certain amount of deferred data to underlying disks. If this happens, the performance will be degraded. So you should avoid "Urgent Writes" as possible by reducing the latency.

I've gone as high as 6 minutes for FTP'ing (to ensure all parts of a multi-part download are re-assembled and the FTP cache never hits the temp drive), but that's sorta overkill too. For regular app use and gaming use, 2 minutes is more than enough.
