Doesn't that HighPoint 23xx card also use the Marvell 88SX7042 chip? I remember seeing the threads about the HighPoint card silently corrupting data by silently writing over parts of the disk(s) with its own info. I'm guessing that's not a "feature" of the Marvell chip, but still... admittedly irrational fear here :) It would be nice if that Supermicro 8-port SATA card (AOC-SAT2-MV8) was available in PCIe... I wonder if it's possible to just graft multiple SiI 3132 controllers (2 SATA each) on a single PCIe card?
