I noticed the areca only has RAID1E, but i guess this is just as good
if not more flexible than 10? This is key too as we will be using
RAID10.. Our case is also not full height or technically riser
capable, though we were planning on buying an 8x riser and using
standoffs to make the full height 3ware work in our 2u case (this
should be fine, but requires a little more effort).
Would we be just as well off going with the areca as the 3ware? Will
both perform just as well?
Also.. we have SAS ability and I know 3ware makes cables that would
work with our non multilane SAS backplane, not sure on the areca,
should we switch a few years later (from SATAII to SAS).

If it is Linux, 3ware is preferrable, since their driver is
in-kernel. The Arcea drivers work well also, but you have to patch
them in yourself. It also has no complete SMART support, which I think
is a big minus. 3ware has. As to dynamic extension, I am not sure
also. We have some Arcea 8 port controllers running, but that question
did not come up.

Its 2003 X64.. from looking at their website.. they appear to have all
the drivers (coming with the card).. No patching needed i guess?
Quite a few have said go with the aerca over 3ware.. then there were
actually a handful that said they had problems with areca, not to do
it, to stick with 3ware...

Microsoft uses external drivers, so this works differently.
Just install them. With Linux you do not need to install drivers.
Both approaches have advantages and disadvantages.

Difficult to say. You may have to try it and in the worst
case switch over to the other. Not ideal, but that is the
price to pay for PC hadware being pretty cheap.
Personally I would go with 3ware, but that is because of the
better Linux support. This may or may not indicate also a
better driver, since the Arcea driver is a source code driver,
but thay did not manage to get it into the kernel. That may
point to either technical or legal issues, I do not know.
The 3ware driver, however, needs to be pretty sound or it
would not have made it into the kernel.

With 3ware, you can query the full smart attributes of each attached
disk. The Linux kernel has a special pass-through function for that.
The windows drivers may also have that. With Arcea you only get
the reallocated sector count (I think), the SMART status (failed/ok)
and the drive temperature. Some people (like me) want more.

Good. I think every server installation should run long SMART
selfteste on each disk every 14 days or so.

No loss. These are a bit obscure anyways.

Aha. That would be a good reason to go with 3ware.

In my searching i have found an article that actually gives lots of
Kudos to Aerca in terms of performance, mostly on what appears to be
for writes and for database/server applications:

Hmm. Ok. Although was this not arranged so that the disk
resumes a test after power outage at the place it was last?

Which happens all the time on servers.
