I have a similar question, I put together a cheapo RAID with four 1TB WD Black

(5GB) for ZIL and the rest of the SSD for cache:

I don't think adding an SSD mirror to an existing pool will do much for
performance. Some of your data will surely go to those SSDs, but I don't think
the solaris will know they are SSDs and move blocks in and out according to
usage patterns to give you an all around boost. They will just be use

But that would only leave ~800MB free for everything else the server
