Hey Robert,
That's awesome to hear! Does that also include UAS
(https://en.wikipedia.org/wiki/USB_Attached_SCSI)
I have a USB3 to msata adaptor that supports and and boy is it fast when
the hosts supports UAS, I got about 10MB/s less than having it on the
msata slot on the board it self!

its probably past time that i invest effort in the usb3 stack. sadly
my current employer has not expressed any interest in that effort.
anyone want to help subsidize the effort ?
For what it's worth, we're already working on an xhci driver at Joyent.
It's something I'm working on as we know there's a lot of need for this
around the community.

You might find that your better off investing in standard spinning
SAS disks but a very good SLOG like the HGST SSD800MH.B, which cost
around $800 AUD. The reason being that in a well built SmartOS box,
you’ll have ZFS ARC occupying RAM from which a good portion of your
database reads should be sourced from and when sync writes do need to
be done, the SLOG will help make them more performant. ARC makes read
performance exceptional for a cache hit. As for zpool layout, for
database workloads your better off with a multi-way mirror (i.e. a
pool full of mirror vdevs) as when there is an ARC miss it should be
performant (at least won’t incur parity penalties in RAIDZ).
The only things to watch out for if your acquiring new hardware is
NIC, HBA and USB compatibility. The best NICs you can have for
SmartOS are Intel based ones (be they integrated onto the motherboard
or as an add-in card), I’ve not had any issues at all with LSI (now
Avago) HBA cards whereas on-board SATA/SAS can be hit and miss unless
they are also LSI based (but can be painful to reflesh if needed).
The USB compatibility aspect is becoming more important as Illumos
doesn’t yet have an appropriate driver which can cause boot issues
and rules out keyboard interactions - some boards have the ability to
emulate USB2, but some work and some don’t.

the vendor stated this:

i hope that was badly worded; though linux has never been the most
reliable of the unix-like systems, i believe it's on a whole
different level from any version of windows. i was once an MCSE but
defected (back) to *nix because i wanted to get real work done
instead of fighting the operating system and related products.
thanks for the suggestions thus far - all good stuff, and i really
appreciate the insight and recommendations. i didn't realize joyent
provided virtio drivers - i've been using the ones from fedora for
several years on the windows terminal server (sitting on
joyent_20140221T042147Z).
i have often wondered about running an all-ssd zones pool. the devs
all poo-poo the use of consumer-grade disks, and sata in general.
and they have made great cases for doing so. but for most of my
uses, the price and potential performance looks extremely
attractive. i don't usually have the ability to drop a couple of
thousand dollars into a disk subsystem for these small
installations. the customers typically already have enough hardware
to run everything bare-metal, but i've tried hard to virtualize
everything for the many benefits provided by doing so (plus of
course the ones specific to using smartos/zfs).

Ideally it should sit on a SmartOS zone but... I understand he wants
to run the database on top of NTFS...(Vendor requirement) however
Sybase ADS its also available for linux.

I would be careful with setting compression, since it can easily be
a
waste of time, depending on the database.
