I am sure that this warranty won't matter to anyone when it comes to actually buying an SSD - let me explain what I mean.
1) Who cares what happens in 5 or 10 years for an average or an enthusiast user? We are gonna have 3-4 new generations of SSDs, I don't think that someone will keep an "obsolete" SSD that long.
2) I believe that they simply put that 10 years warranty label in order to have something eye-catching in order to 'beat' Intel's SSD, which imo are BY FAR the best SSDs out there
