there is a lot going on with SSD at the moment. Benchmarks are very 
promising, however it seems nobody's really using it and some practical 
tests performed by a colleage of mine showed defects on the disks afer a 
very short time (less than a week). So reliability may be an issue with 
SSD, especially with DRBD meta data writes - which really stress the 
write bearing algorithms in the SSD disks.

There have been some discussions about DRBD performance with SSD and 
write bearing already 

I wanted to get some feedback if anyone is using SSD on DRBD in 
production environments ? If so some feedback regarding

- runtime
- performance
- reliability

would be nice.
