Well yes I can choose from various drive options though I don't really know which one is the best one. Just seems that the OWC drives would be easier in that I don't need to fuss with an adapter. Plus their prices seem decent now although I think SSD prices are still way too high compared to "traditional" HDD with the same capacity.
Ok, to put it another way, some people don't trust the quality of the OWC drives.
There's a reason this massive thread exists filled with people choosing the adapter route rather than the alternative 'easier' option.
