Did you read the second link you posted, specifically the Feedback section?
That's one more confirmation of corruption issue we discussed in this thread.

"Cons: Corrupts data when reading from two drives at once (!)
Other Thoughts: I bought this to add 2 SATA ports to my desktop. The cheap
software-based PCIe --> 2x SATA cards seem to be based on SIL3132 or JMB363
chipsets (this is a SIL3132), but this was more highly rated so I went with
it. My intention was to add two individual hard drives to my system, with no
RAID involved. Things seemed fine at first, until I used TeraCopy, which does
a CRC after file copy operations. It revealed occasional mismatches when
copying files to either drive.  Then I noticed MD5 hashes of files on the
drives, taken sequentially, differing without any changes to the files'
contents. The final straw was that reading from each of the two separate
drives simultaneously would result in silent read errors,  to the point where
the file would be heavily corrupted but the OS didn't care.   I stopped using
the controller and bought a 3ware one instead, and it's been working
flawlessly.   I don't know if this is a problem specific to this controller or
its chipset, but I would not recommend it."
