I think that is not so unreasonable for the features you are getting. I
wonder if it would be possible to put the file system data structures on
an SSD? I also have read that it is a good idea to use ECC memory on
such a fileserver, but that's really true of any computer. Undetected
memory errors will cause data loss.

I am inclined to agree. If I was setting it up for a serious production
environment, I would bite the bullet and run Solaris as well.
