I have an Early 2011 17" 2.2 GHz MacBook Pro with 16 GB Ram running latest version of Yosemite. Especially since upgrading to Yosemite a few months ago, this thing is "dog-slow". Takes at least 3-4 minutes to restart and Adobe CC Apps take forever to launch. I have run the latest version of DiskWarrior and CleanMyMac3, but no help with speed. All I can think of at this point to help may be an SSD drive? (1) Your thoughts? (2) If so, which SSD. I have been looking at this one... http://eshop.macsales.com/item/OWC/SSD7P6G480/ Thanks for any input!
