Hi Timo. Wear levelling often isn't as good as is claimed on the box. Often wear levelling is only across subsets of the SSD not across the entire device.

I've seen several SSD drives fail in production after about 12 months of use, and this in low-write environments (eg, I log syslog to a remote syslog server). I'm refraining from deploying SSD for mail servers for now, much as I would love to.

How do they fail? Supposedly once a cell has reached its erase-limit it should become read-only. Maybe the failures had nothing to do with wearing?
