Is there any type of flash-based storage (preferably accessible to end users) that focuses on long term data retention?

If not, that feels like a substantial hole in the market. Non-flash durable storage tend to be annoying or impractical for day to day use. I want to be able to find a 25 year old SD card hiding in some crevice and unearth an unintentional time capsule, much like how one can pick up 20+ year old MiniDiscs and be able to play the last thing their former owners recorded to them perfectly.
