I've recently noticed similar issues with my older Crucial SSD in my 2012 mbp. In the past 3 months, there's been maybe 5 times where I started my laptop and it took 5+ minutes to finish booting. Normally, it's 15 seconds. Once I'm logged in, doing anything takes forever, but it does eventually load. A power off, and back on got it "working" again but who knows for how long. I've had this drive for 4-5 years now, so I'm impressed it's lasted this long.
