I relish these moments. Newbie question time.

It looks like I get to help somebody build a big fat sata raid-5 and
have two questions that other people probably know the answers to.

1 - Does anyone have experience with either:
      Promise FastTrak TX4310
    or
      HighPoint RocketRaid 1740/1742
    controllers? I see that Promise has some sort of open source wrapper
around a proprietary driver where HighPoint theoretically has open
drivers... but I remember bad experiences several years ago where simply
turning on (what I think was) a HighPoint controller prevented my kernel
(2.4.10ish) from booting.

2 - I'm not terribly familiar with SATA. Like... I've not touched a
drive since they were still fairly new. How easily can one plug X+
devices into an X-port card? Is it like ATA where you have exactly 2
channels per interface, or is it more like SCSI or USB?
