Well you should have _actually_ trimmed your response down to not 
pressing send.

_Many_ motherboards have complete RAID support at levels 0, 1, 10, and 
five 5. A few have RAID6.

Some of them even use the LSI chip-set.

Seriously... are you trolling this list with disinformation or just 
repeating tribal knowledge from fifteen year old copies of PC Magazine?

Yea, some of the IDE motherboards and that only had RAID1 and RAID0 (and 
indeed some of the add-on controllers) back in the IDE-only days were 
really lame just-forked-write devices with no integrity checks (hence 
"fake raid") but that's from like the 1990s; it's paleolithic age 
"wisdom" at this point.

Phillip say sky god angry, all go hide in cave! /D'oh...
