I read an article on Gizmodo about choosing the right hard drive. http://gizmodo.com/5496302/the-right-hard-drive-for-you and this is what the article said regarding SSD for OSX: "Unfortunately, there's no way to properly maintain an SSD on OSX today. OSX doesn't support the TRIM command and there aren't any OSX-native tools for Intel drives. The only way to restore like-new write speeds on a Mac is to backup your drive, format it, then restore from your TimeMachine backup. If you frequently write large files, you'll definitely notice the performance hit. For that reason, it's not a great idea to buy a SSD to upgrade your MacBook Pro today." So is it really not a great idea to buy a SSD for my MBP?
