I've got an OCZ Vertex 30gb drive with a 1GB stripe
used for the slog
and the rest used for the L2ARC, which for ~ $100 has
been a nice
boost to nfs writes.
What about the Intel X25-V? I know it will likely be fine for L2ARC, but what
about ZIL/slog?

For the l2arc you want iops pure an simple. For this I think the Intel SSDs are
still king.
The slog however has a gotcha, you want a iops, but also you want something
that doesn't say it's done writing until the write is safely nonvolitile. The
intel drives fail in this regard. So far I'm

Oh, one more thing. Your subject says ZIL/L2ARC and your message says I

ZIL (log) is used for writes.
L2ARC (cache) is used for reads.
I'd recommend
If your clients are mounting async don't bother.
If the clients are
ounting async, then all the writes are done
asynchronously, fully
accelerated, and never any data written to ZIL log.
I've tried async, things run well until you get to the end of the job, then the
process hangs until the

At the end of my OP I mentioned that I was interested in L2ARC for dedupe. It
sounds like the DDT can get bigger than RAM and slow things to a crawl. Not
that I expect a lot from using an HDD for that, but I thought it
