Intel drives and TRIM

"That led to the revelation that the much-vaunted Intel drives do not, currently, support trim. That will change in future versions, though."

It's a property of the firmware; the drive I am testing TRIM with uses a special firmware build on current hardware. I am not able to comment on when or whether firmware that supports TRIM will be available for drives that people already own.

From what I've read on public websites, this appears to be true for other manufacturers too.
