SATA link up 1.5 Gbps

I think it does, but it matters very little. You will not get any
perceptable speed-up over 1.5GB. The one advantage at this time
is better compatibility, and with WDs shoddy SATA protocol
implementation, this may be an issue.

Hmm! Arno, you say "it matters very little. You will not get any
perceptable speed-up over 1.5GB" without saying why ;-)

Which combination of (Motherboard + I/ subsystem + BIS + (?)) will let
you have your cake and eat it too?

Also, which manufacturers have more useful SATA, S.M.A.R.T, TLRE, . . .
implementations so that you may better predict when drives are about to
fail and possibly the physical reasons why

I am thinking of implementing RAID 5 using a Linux (or BSD) software-based
RAID any good best practices out there?

If you need so many disk drives

we were talking theoretically here based on the Math of throughput on each

If you need SATA controller with more than two SATA connectors, you have a
plenty of them. Adaptec, AC (3ware), LSI and some others are producing
those controllers (usually SAS/SATA), and they are working perfectly.

I was actually asking for SATA controller cards based on the PCI-Express
interface

I saw quite a few at newegg.com under:
~
Computer Hardware Hard Drives Controllers / RAID Cards

However they were all either RAID cards or were designed for SAS external
ports

In the same way they have plain 4 port PCI Ultra ATA 133 IDE controller
cards, I wonder why is it they don't have 8 port PCI-Express to SATA II
ones
