TRIM support on MacBook Air (late 2010)

Hello,
could someone tell me if with the next 10.6.7 (and 10.7) will the TRIM support (for SSD) will work also for the new MacBook Air 13" (late 2010)?
Thanks very much!!

This is a USER support forum. We do not know what Apple plans to do for updates to OS X. All we know is that the latest version of 10.6.6 on the new MacBook Pros supports TRIM support for those models only, and OS X 10.7 will support TRIM fully.

Yes, they do make them. But that means just tossing out the one that comes with the Air. That would be a fairly drastic step just for TRIM support. If the original poster had intended on getting a larger SSD anyway... then that would be the way to go... but if they were already satisfied with the capacity of their SSD, replacing it just for TRIM support wouldn't make much sense.

Trim is not needed for Apple SSD's as it is for Windows machines. Apple engineered the drive controller differently. To prove the point MacWorld magazine ran the Air through and intense battery of tests reading and writing to the drive 10,000 times and in the end the tests proved the drive had lost no capacity and it was every bit as fast at reading and writing as a new one.

I upgraded my Air to 10.6.7 build 10J869 (latest beta) and i can confirm that it did not enable TRIM on my laptop.
