It looks like a 4 port version, but you might want to reconsider your need for SATA III. Unless you're running extremely fast SSDs or using port multipliers, SATA II has more than enough bandwidth. Not that there's anything wrong with having SATA III, it's just generally unnecessary.
(1) If for HDDs, you only need SATA II, Sata III HDDs on a SATA III port does not improve overall performance (only burst rate is Improved)
(2) If looking at PCI-e x1 slot cards you run into a throughput limitation going over 2 Drives.
Can move to a x4, x8 card, but here you run into High cost. Also must check available x4/x8 slots. With p55/p67/H67 and Z68 that have daul x16 slots that if you use the 2nd X16 slot, both will then operate @ X8 (knock GPU down 2->4 % performanace decrease - not noticable, just letting you know).
