I don't have any experience with this one. I don't know what
SATA chipset it is using, but there aren't many that the kernel
doesn't already support.

That said, it is a straight SATA3 board, not a RAID board, so
there will be no difficulty in moving mdadm, btrfs or zfs RAIDs
over to it.

I would point out that you can't actually fit 16 x 3Gb/s worth
of bandwidth over one PCIe lane; if this is v1 PCIe, you have a
total of 250MB/s available. That's probably fine for four
spinning disks doing backup duty.

Here's a 4-port model with named PCIe v2 support and a
recognizable SATA chipset, for slightly less money:
