Sorry about that... typos, yay.

The other one looks like a potential malware trap. :-)

I'd have to echo Sebastian mostly. Zfs is great, but the
underlying hardware is... what is. add another 1 tb drive and put
that as Raid 10 (stripe the mirrors), and it'll perform pretty
decently. You'd be surprised. If you have the money, yeah, SSD is
fantastic, but wow... if you are trying to get reasonable size,
you'll spend some cash. Perhaps in this case that doesn't
matter. If you have the money for SSD drives, you might
consider getting 4 reasonable 2TB drives (they sell them for $50
each on gohardrive.com <http://gohardrive.com> anymore for WD RE4
or Hitachi Ultrastars now), and then putting some budget into a
smartOS compatible PCI-SSD drive. Be careful on that - it's easy
to get the wrong drive, but it's not that hard to get the right
one either! That way you'd have your 4 spindles, raid 10 with a
slog, it'd be decent that way, IMHO.

one of my clients owns a supermicro-based box with 4 hot-swap
sata bays. it has integrated SATA and (i believe) no SAS. the
original admin populated it with (3) 1TB SATA disks and
commissioned it as a fileserver (simple raid5). it has 32GB of
memory. the box is no longer being used, so it's been
allocated to me for the purpose of hosting another windows
server. i'd like to virtualize the server via smartos/kvm but
i have reservations.
i believe i can get away with using only 16GB for VMs, so that
leaves 16GB for smartos/zfs - i think that'll probably work
well. but i seriously doubt those disks will give anything
resembling decent performance. i only have 4 bays to work
with, and only one is currently free. for a windows server VM
hosting a multi-user database, would adding a SATA SSD as log
device for the zones zpool keep me out of hot water here or is
this just not going to work?
obviously i can try to source a supported SAS controller and
disks, but i'm wondering if i can actually get by with SATA
... what if i filled the (4) 3.5" bays with SSDs and striped
across two mirrors? would that mostly guarantee decent
performance, or will that just waste time and money?
experienced opinions greatfully accepted!
