I'm using motherboard with an on-board equivalent of this and don't have much to complain about. I did see some CRC errors with SATA drives in 3Gbps mode, but those went away after updating firmware to 1.29.0.0. I've seen some comments on zfs-discuss mailing list that -IR variant of the firmware (the one that provides RAID0/1 capabilities) does have some stability issues and recommended going with simpler -IT version (just pass-through disks). --Artem
