For those of ye who are far more SSD-savvy than I: I have a early-2011 2.0GHz 15" MBP, which stays tethered to a TBD 99% of the time. I am disinclined to upgrade to a retina model because I can't see myself making good use of the screen. I have increased the RAM to 16GB, replaced the battery and I'm considering upgrading the Apple-supplied 512GB Toshiba SSD to something faster. I get write-read speeds of about 140 and 200 MB/s respectively. In its current configuration, this machine Geekbenches about 10,000 ... not that it particularly matters. FWIW, I spend much of my workday in Creative Cloud apps. My question: Would upgrading to a faster SSD make an appreciable positive impact? I think I have everything else going my way - Quad Core i7, decent clock speed, maximum RAM. Would spending the money for a new SSD be worthwhile if I intend to keep the machine going another 18 months? Thanks in advance for your sage advice!
