I wasn't trying to summarize every possible possibility, just the
complicated ones there's some debate over.

What else is OK besides Areca and 3ware?  HP's P800 is good, albeit not
so easy to buy unless you're getting an HP system.  The LSI Megaraid
stuff and its close relative the Dell PERC6 are OK for some apps too; my
intense hatred of Dell usually results in my forgetting about them.  (As
an example,
http://en.wikipedia.org/wiki/ATX#Issues_with_Dell_power_supplies
documents what I consider the worst design decision ever made by a PC
manufacturer)

I don't think any of the other vendors on the market are viable for a
Linux system due to driver issues and general low quality, which
includes  Adaptec, Promise, Highpoint, and all the motherboard Fake RAID
stuff from Silicon Image, Intel, Via, etc.  I don't feel there's any
justification for using those products instead of using a simple SATA
controller and Linux software RAID in a PostgreSQL context.
