I want to build a FreeBSD 9.0 server (my first) with 4 Seagate Barracuda ST3000DM001 harddisks (expandable to 8) and use them with ZFS. The onboard controller is for a SSD and serving the FreeBSD system. After a lot of reading in this forum, using Google for hours, I do not feel comfortable about picking a good 8 ports SATA (II/III) controller. Maybe 2 * 4 ports controller? Please share your thoughts on this with me. Thanks in advance.
