The x4500 uses Marvell JC> 88SX6081 controllers, which are SATA rev 2. Quoting him: Thinking about the controllers: I am still looking for a viable replacement of LSI1068e-based cards for home-built ZFS servers. This LSI chipset does not support drives larger than 2TB which has become a serious limitation for me. I read that the LSI2008 is supposed to be some kind of follow-up, and it should be supported with recent FreeBSD's mps driver. However, I could not find any cheap (non-hw-raid) cards with 8 channels (or more) like there are with the old LSI1068 chipset. Are there any recommendations? cu Gerrit
