Looking for FOSS supported PCIe x4 SATA 6 Gb/s HBA with 4 or 8 ports
debian-user:
I have a system with an Intel DQ67SW desktop board:
https://www.intel.com/content/dam/support/us/en/documents/motherboards/desktop/dq67sw/dq67sw_techprodspec02.pdf
It has the following expansion slots:
- One PCI Express 2.0 x16 add-in card connector
- One PCI Express 2.0 x4 add-in card connector
- One PCI Express 2.0 x1 add-in card connector
- One Conventional PCI bus connector
I need more SATA III 6 Gb/s ports and am looking for a HBA:
1. I would prefer using PCIe x4 slot, but can use the x16 slot.
2. Non-RAID.
3. At least four SATA ports.
4. Can handle sustained loads of ~250 MB/s across all SATA ports
simultaneously.
5. Works OOTB with FreeBSD 12.1, Debian 9, and Debian 10.
6. Works OOTB with SeaToolsBootable_RC_2.1.2.
7. New or used.
My research thus far:
1. LSI products are popular, but:
a. Most seem to be PCIe x8.
b. STFW I see more than a few posts complaining about changing
firmware from RAID to non-RAID, buggy firmware releases, and/or
motherboard BIOS/UEFI incompatibilities with the flash tools.
2. Syba offers products:

a. While migrating backup data, I recently saw a Syba PCIe x1 two
port SATA II 3 Gb/s HBA model SD-SA2PEX-2IR throttling under sustained
load -- it ran at 80-100 MB/s for 4-5 minutes, then at ~7 MB/s for two
hours. Unacceptable.
Comments?
