Correction: the SiI3132 are on x1 (not x2) links, so my guess as to
the aggregate throughput when reading from all the disks is:
3*150+100 = 550MB/s.
(150MB/s is 60% of the max theoretical 250MB/s bandwidth of an x1 link)

And if they tuned MAX_PAYLOAD_SIZE to allow the 3 PCI-E SATA cards
to exploit closer to the max theoretical bandwidth of an x1 PCI-E
link, it would be:
3*250+100 = 850MB/s.
