While this has been pushed around for years in all directions, the answer is yes it is a proven fact of nand technology. Now, it HAS gotten a lot better, but it is still a thing:Do you have any background informations about that?How ssd's are used is really the most critical feature, but long term storage can be in trouble with most if they are not powered up "once in a while" .
I know, time without power is an issue of rotating harddisks, but didn't know, that its an issue for ssd too.
I use ssd for backup of audio/video for about 5 years - and use it in the manner: write once and power on for read when needed.
No issues til now - even with long time unpowered.
My server with raid systems of rotating harddisks had several issues on staying unpowered for a while.
One of the best reads on this is here - and remember TLC is MOST of the SSD tech on the market at this time!
( The average data retention period without power is between 1 to 3 years. )
