TRIM support is finally coming to OS X with the recent addition of the new Macbook Pros and OS X Lion. Supposedly Apple may seed it to the rest of us running 10.6.6 with their next software update: http://osxdaily.com/2011/03/04/mac-o...-trim-support/
TRIM support, for those that do not know, is a software patch that controls how the hard drive deals with files that have been saved and then deleted. The biggest problem, besides price, with SSD's is that their performance is substantially affected by video and photo editing programs. With physical 3.5/2.5 inch hard drives the computer can interpret when something is added, modified and deleted without software interpreting it. But SSD is different, the drives have to be told when sectors have been modified or deleted on the drive. Without a necessary tool to interpret when these files have been modified or deleted, the performance on your drive becomes substantially slower the longer you use it. The only way to increase your HD performance with SSDs is to wipe the drive and reinstall everything, which to a editor or DIT is frustrating, to say the least.
Now, with TRIM support those days are over.
