Correct.

It actually should _not_ saturate the bus too bad during writes
because of that.  But it _will_ saturate the bus during reads because
it will interleave them.

If you're using software RAID to a SATA PCIe x1 channel, then you
should avoid this -- despite the redundant write.  The problem is the
legacy PCI I/O, not software v. hardware.
