 I've had gobs of troubles with this hardware and agreed with the "Don't 
 use" statement (I also had troubles with other SATA controllers, however).
 With two HDs it used to crash and/or lock the system: I tried different 
 HD vendors, different MBs, different FreeBSD versions and architectures, 
 but nothing would help.
 
 This was however until I tried 9.0 release.
 I don't know if the reason is the "new CAM-based ATA stack", but it's 
 been working flawlessly with four HDs for weeks now.
 
 HTH.
