I'm still very happy with the 4 crucial m4 series 128 GB ssd drives I bought back in 2011...
I had thought one had went bad on me, but after researching trying to diagnose what was wrong, it turned out to be a simple firmware update...
And the performance is still above 95% after 3 years use playing AH and recording films every sortie when I play, some films are over 2 hours long when flying FSO....
Crucial use one of the Marvell controllers, different versions depending on the crucial model, the last time I researched it... Although they may have changed recently...
I have to disagree, I've had more issues with Samsung products verses crucial ram or crucial ssd drives..
