Do you, or anyone else with one, know what the upper limit is on
TRIM operations with the Intel SSDs ?

I need to know the maximum amount of TRIM ranges they will process
in a single command.

Eg. Indilinx-based SSDs don't appear to have a limit -- they'll accept
a TRIM command with thousands of LBA ranges included.

Sandforce-based SSDs appear to restrict things to max 4KB of range data.

So.. what about Intel?

Thanks
