# Do modern SSDs outperform HDDs for long-term storage without power?

No.

Modern SSDs are only guaranteed to retain data for 12 months without power. They usually exceed that, of course, but that’s all the specification requires.

All SSDs gradually lose data without power, as the tiny charges in the NAND flash floating gate transistors slowly leak out. Put a hard drive on a shelf and you can still read it in ten years (I’ve tried). Put an SSD on a shelf, especially a modern SSD that stores multiple bits in a single cell, and the data on it will be severely corrupted in ten years.

Another caveman ideology.

It's an insult to cavemen.

Cavemen are intelligent, don't forget that.

Cavemen are the bedrock of technology in the world.

The OP is just an oaf.
