The controller is based on the Marvell 9485 chip and Marvell SATA/RAID
controllers seem to have a bad reputation for reliability:

I have also faced some CRC errors or disk drop-outs/reconnects on 9123 cards,
and in one case all disks (or possibly the controller itself) disappear from
the system until reboot on a 88SX7042 based controller.
