A finding in the developer preview of Mac OS X Lion has confirmed that the OS will have much needed support for auto-tuning solid-state drives. System Profiler now automatically detects SSDs with the TRIM command, and the OS now presumably uses the technique to clean up the drive. The MacGeneration investigation found that Apple's Toshiba-sourced SSD for the MacBook Air was already recognized, but third-party drives weren't yet enabled.
