My first Macbook was a 2011 Macbook Pro (MC700LL/A). It came with a 4GB of RAM and 320 GB HDD. After 1.5 years of use, I was able to upgrade the RAM to 8GB and swap out the HDD for a 512 GB SSD. The performance upgrade was life changing. The effort was minimal. Just unscrew the back panel using a precision philips screwdriver and with little knowledge, one can swap out the RAM and HDD/SSD.
