One item of interest regarding last week's Mac OS X 10.6.8 update reveals that Apple has enabled TRIM support for solid state hard drives shipped in Apple-produced configurations.



From MacRumors:

TRIM is a feature that allows solid state drives (SSDs) to automatically handle garbage collection, cleaning up unused blocks of data and preparing them for rewriting, thereby preventing slowdowns that would otherwise occur over time as garbage data accumulates.

Support for TRIM has been included in OS X Lion since its early developer builds, but Apple has apparently decided to push the feature out to Snow Leopard users as well. The new native TRIM support does appear to limited to stock Apple drives, as users who have installed third-party SSDs into their machines have reported that TRIM is not enabled by the update.
