Some readers have written to inform me that Mac OS X now has TRIM support for solid state drives, basing their statement on the fact that System Profiler now adds one line of text stating whether a drive has TRIM capability.
TRIM is a solid state drive (SSD) feature that turns marginal designs into usable drives. In essence, it’s a command that tells a drive “clean up your internal mess”.
Just because there is a new line of text indicating that TRIM support is present has nothing to do with whether the OS supports using TRIM.
Why would you want an SSD that cannot work reliably (maintain its performance) without regular tune-ups? To get a fast drive (to save yourself time) so that you can waste your time maintaining it? It’s self-defeating.
See my page Mac OS X Support for SSD TRIM for details.
