Those are likely date codes: 2011, week 22. And possibly 8-00B or -00D are board revisions. They may not be identical, but all the components are in the same place and I'd bet software will consider them the same thing. > My posting > http://lists.freebsd.org/pipermail/freebsd-usb/2012-June/011283.html > Lists all numbers off top of chips, (it was very hard to read one > chip, even with magnifying glass & good light, I wouldnt want to > try to read pcture on newegg web page, but people have my IC numbers > for Conrad). The Startech USB chip is the same, a D720200F1. A much better picture of the Vantec version: http://www.expreview.com/9741-7.html Newegg does not have the Vantec any more, but they did: http://www.newegg.com/Product/Product.aspx?Item=N82E16815287007&cm_re=ugt-pc302-_-15-287-007-_-Product Anyway, the eight-pin IC is an Atmel 25F512B, a 512K-bit flash ROM for firmware. It's possible there are firmware updates for these cards, but unlikely the vendors have them for end users. > Newegg.com page has: > "With a built-in SATA power connector, each USB port can deliver > up to 900mA of power" > That's too low, should be 1.0 Amp I believe for USB3 spec. > http://www.conrad.com/ce/en/product/973583/ (english page BTW) clicks to > http://www.produktinfo.conrad.com/datenblaetter/950000-974999/973583-an-01-ml-2_PORT_USB_3_0_PCI_EXPRESS_C_de_en_fr_nl.pdf > Page 2 says: > "each USB port of the plug-in card can deliver a current of up to > 1.5A (SATA power unit must be connected to the plug-in card!)," One engineer is honest, the other is optimistic. :)
