I have an old black macbook from nearly 5 years ago. 2.0Ghz intel Core 2 Duo, build 10K549. Right now it has a 2GB 667 Mhz DDR2 SDRAM on it. A couple of questions: 1) How much memory can my laptop take? 4GB? 2) Will any DDR2 RAM do? For example, is anything from this list here fine? http://www.newegg.ca/Store/SubCategory.aspx?SubCategory=381&name=Laptop-Memory 3) When purchasing an SSD drive, do I just have to look out for a 2.5" drive from this list? http://www.newegg.ca/Store/SubCategory.aspx?SubCategory=636&name=Internal-SSD Or are there any other criteria that has to meet my laptop? Thank you all.
