Forgive me for not being around and posting for awhile. Things just seem to catch up with me. Anyhow. Some good news on the computer front. I have a late 2011 macbook pro 17" It has recently had a new logic board fitted. (Apple free repair) Thinking that the logic board is a major piece of hardware on board I decide to upgrade the original clonky old apple HHD (Hard disk drive) with top notch Samsung SSD 1TB drive. Had a few hick ups on the way but now it is installed my mac is way better then new. the read / write speeds are really amazing and so is the boot from cold. In theory it is 13 times faster then the old platten hard drive. Another bonus is it runs a lot, lot cooler.Thats has to be bonus as well. The point of my post is that if you are thinking about replacing your HDD with a SSD. Go for it. But make sure you do all your research and the process required before attempting the upgrade. It will be worth it.
