I've run more tests and come up with basically the exact same numbers you do.
On Opensolaris - I get about the same from my drives (140MBps) and hit a 1GBps
(almost exactly) top end system bottle neck when pushing data to all drives.
However, if I give ZFS more than one drive (mirror,

Prior to pool version 19, mirroring the log device is highly
recommended.
I have the following.

You probably would not notice the performance effects of a SSD ZIL on a home
network ; so the price of the ticket may not be worth the ride for you. OTOH,
you would notice a significant improvement by using that SSD as an L2ARC
device. Because the head latency on consumer 1TB drives is so long,
What's a good choice for a decently stable upgrade? I'm unable to run
backups because ZFS send/receive won't do full-pool replication
reliably, it hangs better than 2/3 of the time, and people here have
told me later versions (later than 111b) fix this. I was originally

Jim, that ACARD looks really nice, but out of the price range for a home server.
Edward, disabling ZIL might be ok, but let me characterize what my home server
does and tell me if disabling ZIL is ok.
My home OpenSolaris server is only used for storage. I have a separate linux
box that runs

You should understand what it all means, and make your own

There are cases where the SSD ZIL will offer tremendous improvement.
One of the common cases is

Prior to pool version 19, if you have an unmirrored log device that fails,
your whole pool is permanently lost.

This is an interesting question. Today, most ZFS implementations are done
