Many SMART stats aren't particularly useful in predicting failure as they simply correlate to the age of the drive in some fashion.
Also, here is our data on every single SMART stat for all of the drives we have: https://www.backblaze.com/blog-smart-stats-2014-8.html
Gleb (CEO, Backblaze)
First thanks for all your company's sharing of such data, as well as the pod open platform. Kudos.
Second, can you do a Writeup specifically and only about SSDs?
Thanks
It's probably not 5% of our total storage, though.
* even the slowest SSDs have significantly higher I/O rates than the best mechanical drives, and the comparison between best-in-class mechanical and enterprise-class PCIe SSDs is just ridiculous: a 15K SAS drive will do 200 IOPS, a high end SSD will do a million
* 15K SAS drives will top out around 250MB/s on bulk sequential reads (that's a best-case scenario), high-end PCIe SSD are in the 2.5GB/s range
* HDDs have a latency of 10~20ms, SSDs have a latency of 100~200µs (RAM has a latency of ~100ns)
Have you productized these learnings in a a powertop-like tool for Linux?
Smartmontools are not intuitive enough for the layman to use in any meaningful way.. And backblaze has really built some serious learning here that could be of use to everyone.
