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. G. Mirov
