Mac OS X Lion Supports TRIM for SSD’s

Mac OS X 10.7 Lion will support the TRIM function for SSD’s, this should significantly boost the lifespan and performance of SSD drives. Hints for support were first discovered last year by Anandtech, but now HardMac has confirmed that support is included in Mac OS X 10.7 Lion Developer Preview.
TRIM is important because it allows the operating system to notify an SSD which blocks of data are no longer in use on the drive, allowing them to be wiped and written over more efficiently. Without TRIM, an SSD drive can become gradually slower over time as blocks that were once in use become slower to write new data over.
