While this often enables undelete tools to recover files from traditional hard disks, despite the files being reported as “deleted” by the operating system, it also means that when the operating system later performs a write operation to one of the sectors, which it considers free space, it effectively becomes an overwrite operation from the point of view of the storage medium. Since a common SSD has no knowledge of the file system structures, including the list of unused blocks/sectors, the storage medium remains unaware that the blocks have become available. Contrary to, for example, an overwrite operation, a delete will therefore not involve a physical write to the sectors that contain the data. Delete operations are typically limited to flagging data blocks as “not in use” in the file system.

I found a great utility to enable TRIM on 10.6.8-10.9.5: Trim Enablerĭon’t forget to reenable it after each OS X System Update.īecause of the way that file systems typically handle delete operations, storage media (SSDs, but also traditional hard drives) generally do not know which sectors/pages are truly in use and which can be considered free space.

Makes it easier to reenable after a software update. Second, Trim Enabler has a feature to check on startup. First, Chameleon has some compatibility issues. I switched my favorite utility from Chameleon SSD Optimizer to Trim Enabler. You can check your TRIM status from the System Profiler/System Information under SATA by selecting your device.

Not only that, but if you manually enable it yourself, it is then disabled during any OS upgrade (i.e.

Apple introduced it in 2011, but believe it or not, even today, Apple refuses to automatically enable TRIM for 3rd party SSD drives. Technology was needed to offset this failing. As a result, the way that operating systems traditionally use these devices lead to progressive performance degradation and even shortened lifespan.

These are the recommended methods for enabling Trim in Mac OS X: Snow Leopard 10.6.8: No issues, use Trim Enabler 2.At the device level, SSD drives function entirely differently then conventional mechanical disks.
