I'm looking to prolong the life of my MacBook as it may be awhile before I can afford a new one. Specs: 13", Mid 2009 2.26 GHz Intel Core 2 Duo 8 GB 1067 MHz DDR3 250 GB harddrive, original Hitachi, 5400 RPM NVIDIA GeForce 9400M 256 MB OS X 10.9.1 What I've done: updated from 4 to 8 GB RAM (see specs above) put a new battery in it moved items off the hard drive so that I have 30GB free ran a full virus scan It has been sporadic and unresponsive at times (too many "beach ball" episodes), although is running just fine at the moment. Not sure what to make of that. I had originally assumed the new operating system was bogging it down. Short of rolling back my operating system to a prior version (would that even help speed things up?) I'm guessing my best option may be to upgrade the hard drive? Options I've Found: 240GB SSD from Crucial for $130 or 256 GB Solid State Drive from iFixIt for $230 1 TB SSD Hybrid 2.5" Hard Drive from iFixIt for $160 or 500 GB SSD Hybrid 2.5" Hard Drive for $120 What is the difference between the true SSD (option #1) and a hybrid (option #2)? Also, in item #1 what are the differences (besides the large price difference) between the SSD from Crucial and the one from iFixIt? Thanks!
