thank you very much, that helps a lot. I used the detailed information you
provided to search for chipset details and it seems that at least IB-251U
and IB-270U are based on the Cypress 7C68300A-56PVC chipset, so the
3.5" units like the IB-351U are probably based on the same chipset.

Device(0x6830) reveals that it's a Cypress xx6830xx chipset based bridge,
but Is there a way to find out the exact chipset ID (Cypress 7C68300A-56PVC)
of a connected bridge under FreeBSD?

Could you tell me what kind of read/write performance you get with and
without the Icy Box enclosures you mentioned? Thank you.
