I installed a crucial m4 into my new macbook pro 13", and had a tonne of issues; spinning beach balls etc. After checking the problem online it became apparent that this problem was quite common and was due to the ssd being sata 3 and my laptop's connection being only sata 2. I tried every single fix that was recommended including the upgrading of the ssd firmware. This did not resolve the issue. I am now going to return the m4 and I am looking to buy another ssd. I assume that for 100% guaranteed compatibility i will have to go for a sata II SSD? If this is the case what is the fastest sata II SSD I can buy / what is the fastest ssd that is guaranteed compatible?
thanks
