Hi all, I've owned my 27" iMac mid-2011 since new and over the past year have noticed it's finally beginning to slow down. This is probably just from the HDD gradually filling up over time but I've also begun to hear a "crunching"(best word to describe it) sound that is most definitely coming from the HDD. I've been considering it for a while, but only recently have I decided to upgrade to a SSD alongside the existing 1TB HDD. I have also decided to upgrade from the existing 4GB of memory to 8GB due to concerns of possible bottlenecking. I plan on using parts from OWC. I have a few questions regarding these upgrades. Will adding an SSD to the system have ANY negative effect on the life of the machine or on system performance? I do not have any evidence to make this a credible fear, but checking coudn't hurt. Once done installing the new parts, will I need to restore from a backup on Time Machine? I have a Bootcamp partition with Window's 7 and other data installed on my 1TB HDD. Will adding the SSD require me to repartition my HDD with Bootcamp, effectively requiring me to reinstall the programs on the Windows side of the machine? How would I go about installing OS X on the SSD and using the 1TB HDD as "deep storage" for things like old documents, videos, photos, etc? i.e. Can I choose which files save to the SSD and which files save to the HDD? Also: Could a Bootcamp partition load the OS(Windows) from the SSD and save data to the HDD? If it is possible to load OS X from the SSD, can the rest of my files/programs be restored onto the HDD and sorted between the two drives later? Would a 120GB SSD be enough, considering I want to load OS X and Windows from the drive while still having space for some files, or should I opt for the 240GB option from OWC? Can I just add two 2GB sticks of memory to the system for a total of 8GB, or should I purchase two 4GB sticks instead? Is OWC a good company to use for parts regarding price, quality, warranty, etc? Are there better options? I've attached screenshots of the "About This Mac" window for my machine. As you can see from the "Storage" section, I have a Bootcamp partition of 150GB which is where Windows 7 and a few programs I use for school are located. I do use Time Machine to back up this machine. I have also included a screenshot of the items I plan on purchasing from OWC. Also, sorry if this is in the wrong section, this is my first post.
