How long, exactly, do SSDs last?

It’s a difficult question to answer because estimating an SSD’s life requires taking a whole lot of factors into consideration—type and amount of NAND used in the drive, overall write amplification, read/write cycle, and more. TechReport…has been subjecting six drives to a long-term torture test to actually measure, rather than estimate, the drives’ service life.

The results are impressive: the consumer-grade SSDs tested all made it to at least 700TB of writes before failing.

The long term viability of SSDs has always been a concern so it’s good to see reports like this coming out that may put some of those to rest. The speed improvements of SSDs are definitely worth it.
