I'm having a trouble with my MacBook Pro (Mid 2012).
I have upgraded it (5 months ago) to use a Kingston SSD instead of a SATA, and everything was perfect. Very fast and smooth…until yesterday. I was working and then when it was time to go home, i just pull down the monitor and the macbook went to sleep. When i came home and open my MacBook, it was just a disaster, EVERY SINGLE action, even click on any button, causes to freeze and the apple colorful ball (loading) appears.
Today i tried to put another SSD (samsung) to test if was my SSD that has a problem, but the problem remained. Then i tried to use a simple SATA and everything is normal (i'm asking now from my macbook with a SATA HD).
What do you think it could be?
This are my configs:
– MacBook Pro Mid 2012
– 13"
– i7
– 12Gb RAM
– Intel graphics 1024
– El Capitain OS X
p.s.: My SSD is almost full.

It sounds like you have a faulty SATA cable. Others have reported this same problem when upgrading from a standard HD to a SSD with Mid-2012 MacBook Pro laptops.
