I need to set up a server with two RAID1 SATA drives to do mirroring. I was wondering if there was any point in using software RAID controllers like FastTrak S150 TX4. I've found some info avaliable for Linux and people say kernel raid is as good as any BIOS raid. Would that be true for FreeBSD as well? Also using a PCI card for the disc drives in place of the built in SATA interface may degrade performance, since the built in SATA is probably on a different PCI bus to plug in cards. So what would you guys suggest? Keep the card or go for inkernel implementation? Marcin.
