[QUOTE="JMN, post: 249831, member: 8469"] With case data having state mandated retention periods of 3-5 years in many places, SSDs just aren't there yet. 5 years if right about the theoretic lifetime of the current consumer level drives. They use, generaly, MLC or some even TLC NAND flash memory. These chips all have a finite write cycle before they will experiece 'burn' at the memory cell level, and not either not store the data given them or in some cases it will be corrupted when written at that point. Case data is generally not moved around on a drive, but stored once a left alone. Thus it *may* be perfectly safe, unless a transformer blows nearby creating a minor EMP event, or you have a fire, which spinning platters will survive. It's just still young technology. Also, it's data availability and retention paranoia for litigious reasons and re-make-ability to retread a all-on-four type case among other reasons. Anyway, if you back up like you should...
