I'm not using the card's raid features. As a standalone drive controller, it should be no different from a non-raid version (it's HPT302 instead of HPT372) and therefore should do the job normally i.e. with proper I/O speeds. > I won't use a 1520/1640. I think they are also fakeraid. yes, they are. I'd be interested in finding out decent and well supported (linux opensource drivers, preferably in kernel tree) low-end (cheap) non-raid SATA controllers for 2/4 drives. best regards, pedro venda. -- Pedro Joćo Lopes Venda pjvenda < at > arrakis dhis org http://arrakis.dhis.org
