Hello everyone. I am planning to buy a used MacBook7,1 (Mid 2010). I would like to upgrade it to SSD (probably Samsung 830 or 840, which has read speed about 510 MB/s). The problem I see is that this computer has SATA II connector (max 300 MB/s) in hard drive bay. So I was wondering what would the performance be? Will it work without problems (SATA III vs. SATA II)? What would be the read speed in practice? I suppose in theory it would be 300 MB/s. My next question is regarding the RAM upgrade which I would add 16 GB (2x 8 GB modules). I was wondering would 1333 MHz work OK? I read some posts that the system works well but the graphic card freezes the system (MBPs 2010). Why 1333 MHz and not the default 1066? Because later I might switch to MacBook Pro 2011, which has 1333 MHz. Thank you in advance for your helpful answers!
