About six years ago, I changed my second MacBook Pro to SSD and loved it. That machine had networking problems and I replaced it about four years ago with a mid-2014 MacBook Pro with a 500 MB SSD. Love it. Dead silent and fast as blazes.
I only have spinning drives in my backup servers and audio/video servers. Everything quietly gets backed up via Time Machine and Synology.
My 2012 MacBook Pro was getting slow and I was considering getting a new one. Then I looked into SSD drives, put a Samsung 1TB drive and it was like getting a new computer. Spent $200 instead of $2000 and I avoided having to deal with new cables etc.
