Datacentre SSD failure rates
So at the last USENIX conference, a study on SSD failure rates in googles datacentre's was released with some interesting findings.
- Age, rather than usage amount correlates to higher error rates.
- While flash drives offer lower field replacement rates than hard disk drives, they have a significantly higher rate of problems that can impact the user
- Drives tend to either have less than a handful of bad blocks, or a large number of them, suggesting that impending chip failure could be predicted based on prior number of bad blocks.
