TRIM enabled on MBA SSD?

Hi all,

Is that really necessary to get TRIM enabled on MBA SSD? I just got new MBA ultimate that comes with Samsung SSD.

Thanks.

It won't hurt matters, but it does involve installing a hack that discussed in the Mac Pro forums (try a search of TRIM Support Enabler). It installs a kernel extension from the current MacBook Pro versions of 10.6.7, which do support TRIM on Apple's OEM drives. Anyway, TRIM is coming officially in OS X 10.7, which is expected as early as June. In 2 months (or even 6 months with average usage), your drive performance shouldn't degrade enough so that you would notice. The newer drives that Apple uses are a lot better than older SSDs were.

If you are so inclined, you can boot into Windows 7 write FF's to recover any partial NAND blocks.

The SSD's in the Air's have decent garbage collection, so this isn't really necessary. Some may even recommend against it due to the extra duty cycles involved.

I wrote up a somewhat detailed explanation of GC and Trim on NBR for a Sony Z1 I purchased.

I'm going to attempt a transplant of the Sony 512GB SSD "sammich" into the 13" MBA sometime this week. Not sure if the cables are going to line up, but the PCB's will fit.
