I'm seeing the same thing on a 3114. (And even uber flaky behavior on a 3ware 8506-4LP... rebuilds succeed, OS can pattern fill the array without error, but a media scan/parity check fails within minutes.) There's likely nothing wrong with your drives. Something about that driver and the hardware aren't playing nice.
I have 4xST3160023AS's in RAID0 (mirroring what the BIOS does to those drives. See other posts.) I can zero the array @ 35MB/s via O_DIRECT writes without any issues. I can copy gigs of stuff into the array if the fs is mounted O_SYNC. Yet, without O_SYNC, bursts of writes eventually result in a DMA timeout. I tried setting SIL_QUIRK_MOD15WRITE for that drive model, but it makes no difference.
