After our adventure in figuring out the particular ExpressCard version of the StarTech USB 3.0 adapter
, here's Buffalo joining the fray and, naturally, there's zero indication about whether this is an ExpressCard 1.0 or 2.0 device. The difference is that with the latter you can get all the way up to 5Gbps theoretical throughput, which is just above the USB 3.0 max rating of 4.8Gbps (typically advertised as 5Gbps), whereas the former hardware will get you only up to 2.5Gbps. Considering there's a pair of USB SuperSpeed ports on there, you'll want to make doubly sure you're getting what you think you are. Or, given that early bird UK e-tailers are listing it for £35 ($57; no stock yet), you could just order one up and pray to Cthulhu that you get the maximally awesome stuff.
