freebsd-questions:

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:

 
https://www.sybausa.com/index.php?route=product/category&path=64_181_85&filter=38,74

     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?
