So, I have a 2008 black macbook, that is running super slow these days. I have already upgraded the RAM to 4 GB (did it when bought the macbook in late 2008). So, now I am thinking of swapping the HDD with SSD. But, I have no idea what SSD to buy, what to look for. Only reason I got interested in SSD is reading here that SSD's improve the performance, and there is a good deal on 240 GB SSD, for about $110. Here are two ( I dont know the difference between these two, if there is any ) Crucial M500 240GB SATA 2.5-Inch 7mm (with 9.5mm adapter) Internal Solid State Drive CT240M500SSD1 and Crucial M500 240GB mSATA Internal Solid State Drive CT240M500SSD3 Please advice. Also, is it even doable, though google search shows it should be easy, but want to hear from experts here who actually own macs.
