"The only generic advice I can give you at this point) is to avoid
Silicon Image controllers, particularly their SATA controllers.  They
have a history of causing data corruption on Linux, FreeBSD, and
Windows, and some have reported other miscellaneous problems with them
as well."

"I've had problems with XFS and EXT4 over the md device driver that turned out
to be a bug in the Silicon Image 3132 chipset.  It quietly corrupts data."

"...Sil3132 2-port SATA-card which couldn't handle heavy load on both ports.
Single port was fine, so preclear did not reveal any problems. I have one
working and one non-working coming from the same supplier and looking almost
exactly the same so it would be impossible to know before hand which card
make/model might cause problems. In this case random read errors were produced
for the two attached disks."

"This might be the Sil3132 itself that's creating the problem. It's somewhat
notorious for corrupting data under high IO pressure. It's trivially easy to
trigger if you're using both ports at the same time, but I've seen similar
data corruption with just one port under active use."

"There are confirmed problems within certain models of their SATA controllers
which cause silent data corruption and other issues, affecting Linux, FreeBSD,
and Windows. ... I'm not even willing to trust later revisions like the 3124;
not catching data corruption during QA/testing is simply unacceptable
regardless of what "class" of product it is.  I would be very surprised to
hear someone advocate use of Silicon Image controllers after reading the
above."

Can fully agree with this. :)
