After much thinking and researching, I decided to pull the trigger this morning and purchase a Crucial 256 GB m4 2.5-Inch Solid State Drive SATA drive to replace my failing 640GB WD Blue drive in my 2008 MacBook Pro.
My current drive started giving me hard drive warnings the last few weeks. Upon further investigation (using Drive Genius 3 and TechTool Pro 6), I was able to discover possible SMART issues. Also I am getting the beachball effect the more I use my Macbook Pro.
I will get my drive in a few days and backup my drive.
Since Apple is going to release Mac OS 10.8 (Mountain Lion) in July, I will install the SSD in the Macbook Pro and do a clean install of 10.8.
