I am currently assessing upgrade options for my mid 2010 unibody macbook. Over the past few months my machine has slowed to a screeching halt & it's my main machine for running a small business. I was considering upgrading to a newer machine but financially it's out of the question. I ordered a RAM upgrade that should arrive today (2x 4GB sticks). I've been doing some research for the past few weeks and have decided to take the plunge on an SSD. Originally I planned on installing a 120-8 GB SSD in place of the stock 250 GB HDD and using that drive in an external enclosure to store music, videos and pictures. Now I am considering going all-out and replacing the rarely used optical drive with the stock HDD and creating a dual disc machine to avoid lugging around an external HD that I would use frequently and risk damaging/ losing. Im also considering a smaller storage capacity for the SSD as I would use it only for the OS and applications and the HDD is more than enough for my files and media. I'm having a hard time finding anything online in regards to the pros/cons of doing this (though I'm finding plenty of how-to tutorials) Does anyone have personal experience in doing this? Opinions? How easy/difficult is it to manage 2 drives in terms of permissions and keeping different files on different drives? Thanks!
