Our take on the Supermicro AOC-2020SAH1 PCI Hercules1 Low-Profile SATA ZCR Controller Card

The Supermicro AOC-2020SAH1 is a low-profile PCI add-in card that provides SATA RAID with zero-channel RAID (ZCR) offload. It is a legacy server part, built for older Supermicro platforms that have a dedicated ZCR slot, and it moves RAID parity work off the host CPU. It suits people maintaining or repairing aging Supermicro servers, not anyone building a modern system. Compared with current SATA or NVMe controllers, it is slow, limited to older SATA drives and tied to specific motherboard slots.

Questions and answers

What is a ZCR controller card?
ZCR stands for zero-channel RAID. The card handles RAID parity calculations so the server's processor does not have to, and it uses a dedicated slot rather than standard drive channels.
Will it work in any PCI slot?
No. It is designed for Supermicro boards with a ZCR slot. Check your motherboard's slot layout before buying, because a standard PCI or PCIe slot will not run it.
Which drives can I use with it?
SATA drives only. It does not support SAS or NVMe, so it is limited to older SATA disks and the RAID levels the card's firmware offers.
Is it worth it over a modern RAID card?
Only if you are keeping an older Supermicro server running. For a new build, a current SATA or NVMe controller gives far more speed, capacity and support.
What comes in the box?
The card itself, in its low-profile form. Cables, brackets and documentation are not guaranteed, so confirm the contents with the seller before ordering.
Where is the Supermicro AOC-2020SAH1 PCI Hercules1 Low-Profile SATA ZCR Controller Card cheapest?
At Gotodirect, for $609.04, as of our latest check.
