I have just purchased MacBook Pro (Mid 2012) Model A1278. Although I have already upgraded RAM from original 4 GB to 2 x 8GB.
Now I want to upgrade 500GB HD to 1TB SSD. This can be easily purchased from Amazon. Most likely Samsung EVO 850 1TB. I have few technical questions before I invest $360 in purchasing this SSD. My Google / YouTube research just talks about form factors and how fast the performance is compared to Hard Drive. But nobody talks about the technical nature of its assembly within the Apple MacBook Pro. They make it sound, just buy it and replace your HD with this SSD drive. Period. I am not exactly sure if that is a true statement for MacBook Pro (Mid 2012) Models.
1. Does this particular MacBook Pro Model A1278 support mSATA SSD or just only SATA III SSD?
2. What is the power consumption like and sustaining temperature. The last thing we want is to compromise battery life for better speed and overheating base. I mean between mSATA and SATA III SSD.
3. mSATA vs SATA III Pinouts - are they the same (Signalling + Connector), to fit in the existing hard drive slot? Do I need to buy separate connectors/adapters.
4. Some say that mSATA is 5x faster than SATA III SSD. If that is the case why one would even consider purchasing normal SSD, when Amazon prices are almost the same for either model.
