Mulling over the idea of replacing the traditional HDD in my Lenovo X230 with an SSD. What are the pros and cons of mSATA? Power consumption isn't that much of a concern for me. I suppose the main advantage of using mSATA is that it'd allow me to keep the old HDD in there in case I needed the extra storage. From a pricing perspective, both SATA and mSATA seem to cost about the same these days.
