dolph_rex, I'm considering buying the StorTecc USB3/FW combo drive from Dealsonic.com (
http://www.dealsonic.com/stpmblsmbaco2.html). This particular enclosure has the Prolific PL-3507 which is used for both the USB2 & Firewire ports.
Someone on CDFreaks.com, used an ext. enclosure with this chipset (diff. mfg) on his BenQ and had bad results. It was probably be he had an older chipset (Pm37LV512) which doesn't flash at all, but the newer one (Pm39LV512) does have the ability to flash.
Btw, which article shows the BenQ used in ext. enclosures? I tried looking for it but haven't found it at the moment. If this enclosure I want to get from Dealsonic.com isn't compatible with the BenQ, then my choice will be the NEC ND-3500A.
