How many ports? If you want up to 8 drives (but more than 4),
THIS works very well. If you need more ports the 71605E is a good card for up to 16 drives, but I don't think it comes in a kit package with the 8087 mini SAS to 4 SATA cables like the 6805E, which includes two cable and saves you a fair amount by going in kit form.
There is also a smaller 6405E that can handle 4 SATA drives.
If you want the option of RAID 5 or 6 available, the cost goes up quite a bit, and there I would look at the Adaptec series 7 cards. And if you will use SAS drives you need a different cable model.
