NEWSFLASH: today we replaced the 4x500GB Seagate drives with 4x1.5TB
drives and reconstruction of the array has been running for 2h without a
glitch.

One interesting difference is that the 500GB drives were being
configured in 1.5Gbps SATA mode. Another notable difference is the
sequential read speed: ~70MB/s vs ~130MB/s with the 1.5TB model.

Could the PCI bus errors be a red herring?
