On older 3ware controllers that can only do SATA-1 speeds (1.5 Gb/s) you 
need to jumper SATA-2 drives to force them to use the lower speed.  The 
auto-negotiation doesn't always work right, and I've seen non-jumpered 
SATA-2 drives kicked out of the array under heavy load.  I know this 
applies to the 95xx controllers, possibly some others.  On Western 
Digital drives you do this by shorting the OPT1 jumper.  I don't know 
about other brands; some may not even have a jumper for this, and I 
wouldn't recommend using those with older 3ware boards.
