Apple may handle TRIM drives in Mac OS X

The current-run 13-inch MacBook Pro may have given away the first signs that Apple is implementing TRIM support for solid-state drives in Mac OS X. Attaching an SSD to the 2010 system will show an entry for "TRIM support" that doesn't exist on the Core i5 or i7 MacBook Pros or earlier models. The support appears very rough and incorrectly flags TRIM-capable drives as lacking support.

TRIM is considered important to the future of SSDs, as it will keep them running at peak speed for most of their useful lifespan. Older SSDs often slow down over time as more of the drive space is used and the system has to erase more and more junk data, such as deleted but not missing files, before it can write new information. TRIM aggressively erases these areas so that they're truly empty in advance of when new content needs to be written.

Windows 7 and Windows Server 2008 currently support TRIM, but Apple so far hasn't had native support and has seen less benefit from faster SSDs as a result. Adding the feature would let Macs use the full features of modern SSDs and could lead to significant storage updates for the MacBook line and other Macs that have SSDs as build-to-order options.
