Question on siig sata 3 controller

["Alan" <alan@clueserver.org>]

Does anyone know the status of the SIIG DP SATA 6Gb/s 2S1P PCIe (Part
number: SC-SA0E12-S1)?

I am encountering problems writing a large quantity through this
controller and I want to see if there is a way to fix this.  The pci ids
do not appear to be referenced in the kernel.

Are any of the siig sata controllers supported? Is there some issue with
them supporting Linux that I am not aware of?

Here is the lspci data:
