Hi everyone, I have a mid-2011 27" iMac with a 1TB HDD and 12GB of ram (3.1ghz i5) - I'm getting frustrated with the performance hit, specifically during backups, using either crashplan or CCC, and I'm running low on space. I thought I would upgrade by: 1. replacing the 1TB with a 240gb SSD (Sandisk Ultra II $70 on Amazon) 2. removing my optical and adding a 960gb SSD (Sandisk Ultra II $227 on Amazon) using OWC's DataDoubler. Keeping OS and apps on the 240gb and moving all media onto the 960gb. I have roughly 350gb of photos, 100gb of video and 80gb of music. I thought about just doing the main drive and using external storage for media, but I already have two 1TB enclosures for backup using CCC and don't want to add another 24/7 power brick to the energy drain (electricity is relatively cheap, I know). Will the 240gb drive be enough for OS, MSOffice, Lightroom - nothing else really, except for the native Mac apps? Altogether, this will be roughly a $350 upgrade with tools, is it a wise investment? The computer is generally quick enough and capable of handling my needs, the LCD was replaced right at the end of it's Applecare - so no problems there. Thanks!
