TweakTown posted a review on the Areca ARC-1231ML SATA RAID 6 Controller

So, where do you turn to when you run out of ports on the motherboard? - To a discrete solution of course! There are many companies out there providing a huge array of cards.

Areca is a new company to TweakTown; we haven’t been graced with any products from them until now, and as always we are more than happy to oblige them with some testing of their products. Today they have sent one of their biggest cards for SATA-II expansion. In our labs we have been sent the ARC-1231ML 12 channel SATA-II Controller. Let’s get stuck right into it.
