Are any of you using the Intel 320 as ZIL? It's MLC based, but I
understand its wear and performance characteristics can be bumped up
significantly by increasing the overprovisioning to 20% (dropping
usable capacity to 80%).
A log device doesn't have to be larger than a few GB, so that shouldn't
be a problem. I've found even low cost SSDs make a huge difference to
the NFS write performance of a pool.
