ATA/SATA RAID cards??

[WipeOut]

Hi,

I am looking at using ATA RAID on a server I am going to be putting 
together pretty soon..

There seem to be a number of these cards on the market now, namely 
3ware, Adaptec, Promise and ICP/Vortex.. I guess there are probably 
others as well..

Which of these cards just work?? What I mean by that is which don't 
require a seperate driver to be added at install time or don't have 
issues when it comes to kernel upgrade time??

Hearing about your experiences will help a lot in making the choice..

Later..
