While some of those Crucial drives are Micron and pretty reasonable, please beware of comparing "consumer drives" and drives from 2012 / 2013 with today's drives.
The real problem with drives is their firmware has to garbage collect. So, yes, you can push a drive into a corner where it can't escape. Not to name names, but I've had this happen in my company's testing of different drives. That also means there are peculiar results, such as needing to restart the drive, or let it sit for an hour, and seem much better.
Our experience with MLC ( managing and observing many customers' Flash deployments ) has been very positive, and when using major manufacturers' drives works very well.
