These SAS HBA cards must have the IT (initiator target) mode firmware because the default firmware (IR mode) supports a version of hardware RAID, which I did not want. With the IT mode, the hard drives will be logically separated on the card and only share the physical bandwidth of the PCIe bus. This is a must for ZFS.<\/p>\n\n\n\n<p>With these new cards, my write throughput to my NAS hard drives now averages around 500MB\/s. Previously, I was only getting about half of this.<\/p>\n\n\n\n<p>I wish I would have found these sooner. Now I have two spare PCIe SATA expansion cards, one supporting 8 ports, and the other supporting 16 ports. I will place them on another server. Perhaps in a future Proxmox cluster project.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>About three weeks ago, I was casually browsing eBay and found this little gem, a Host Bus Adapter that can do PCIe 2.0 x8 (~4 to 8GB\/s).
