SanDisk Ultra II 480 died

same thing happened to me . I honestly dont care about warranty. but going forward I’ll not use SSDs. Too unreliable, we’ve had 5 SSD drives dies. MTBF figure are all false.  Every SSD seems to die at between  to  years. My belief is Microsoft OS is the problem, pagefiles system and other  background  burns controllers and cells out.   Some place claim they can retore SSD data by:

a) replacing the controller, or

b) replacing the connector.

immediately after getting the drive up back up  copy all data to new drive.
