Excellent -- this is the exact kind of information which is needed.
It appears the utility can indeed obtain all SMART statistics from
the drive, rather than just an overview: awesome.

Based on past readings about 3Ware controllers, I have a tendancy
to avoid them. Here's some history I base my opinions on (and a
small bit based on feedback I've gotten from people at Rackable):

(see rwatson's comment in this one)
Now, those reported issues could be a number of things, but firmware
issues seem to stand out like a sore thumb. Also, a lot of my
information is in regards to the 7xxx series, which is "quite old".
I'm assuming everyone now is using the 9xxx series, and I have no
idea what those are like.

I've never used Areca, so they're new to me. Good to know -- thanks!

There's no need for compat4x because the binary is statically linked.
Not to be sore about it, but I'm questioning a vendor who only builds
tools on 4.x machines (surely they *test* their controllers on 5/6.x
and -CURRENT, so why is the management utility for 4.x?)
If the utility works perfectly, great. But surely you can see where I'm
coming from...

I'm used to the big boys: Intel, EMC, Adaptec, Sun, Network Appliance
(if they fall into this category) and Promise, so you'll have to
excuse my ignorance. From the look of feedback provided here, Areca
looks to be an excellent contender. I have zero interest in Intel
and Adaptec (especially the latter), and EMC, Sun, and Netapp are all
too expensive for consumer use.
And yes, AMCC deserves a shout-out for being FreeBSD-friendly. Even
though I don't have one of their controllers, it doesn't matter -- I
am always appreciative of vendors who believe in testing their
hardware on more than just one single open-source OS (Linux ;) ).
Thanks.
