question on sata controller cards

I want to do a new system config with sata hard drive. I been looking around for reviews on the bandwidth between sata controller card and pci bus. What i understand is if you have a UATA board supporting 133 then your pci bus is 133 so the sata card would have to share the bus speed with all the other cards. But then I read that the pci bus speed increase ( which we all know ) when you increase your fsb. can anyone clarify this statement?
 
Lord, this is no longer the case. Any motherboard worth working with has an AGP/PCI lock so the AGP and PCI buses run irrespective to the FSB.
 
pci cards are usually really sensitive to bus speed changes... so most mobo's keep the buses locked irrespective to fsb
 
Good show, Now I see it's pointless ( not really ) to get sata at this time since sata is going through some upgrades 300 m/b s then 600 or 800 m/b s. I'll use it then.

I wouldn't call it pointless. Well, maybe if you had to buy a PCI card. I love my Raptors, so going to SATA was a good switch for me.
 
Not pointless if you are using a baord that has the Intel ICH5R contorller. It supports SATA naitiveley and as such any raid array using the ICH5R has its own dedicated bus and does not use the PCIU bus.

An Ausus P4C800-E for example

also the kt800, nforce 3 (i beleive) support it natively. the board specs should declare whether it has native sata through the south bridge, or uses a controller (normally either promise or silicon image)
