So SanDisk knows they have a firmware problem and this is the cause for 90% of the Ultra 2 SSD failures. They refuse to address the problem and extend the warranties of the drives.
Just the drive failure is a pain to deal with but so is replacing 47 more drives we have before they fail. We have decided to use another companies SSD drives. Guess they don’t care about losing 10k of sales plus future sales to other companies due to poor customer service.
