Looking to speed up my Rev. A, 1.6ghz, 80gb HD. I am thinking a SSD, but none seems very fast looking at the specs, 75MB/S write, 85MB/S read. My OCZ Vertex Turbo 2.5" SSD in my MBP does 240MB/S read & 145MB/S write for LESS money. Am I really going to fell the speed difference with a SSD? Is there anything else I can do?
