There's no Ethernet on most Ultrabooks as epitomised by the Macbook Air. So what do you do if you want to connect to a SAN at high speeds?
Until recently most upmarket laptops sported a 1GB Ethernet port. If you were to follow the historical timeline for the development of portable PCs you might be tempted to think that the next step up from the 1GB networking standard might be 10GB Ethernet. But it isn't: it's no Ethernet at all - at least if you've got a MacBook Air.
These Manilla Envelope-sized laptops are simply too small to incorporate a full-sized RJ45-type network socket. This, together with the fact that most people would use the built-in Wifi most of the time, and having cables - especially inflexible network ones - is pretty inelegant with these stylish computers.
But as Macbook Airs get more powerful and come with more storage, they're appealing to Media professionals, who, on balance, would rather not have to lug a leviathan of a workstation around with them. Airs are getting seriously fast.
Until now, if you've had to plug a network cable into your MacBook Air you'll have had to use the Apple USB to Ethernet adaptor, which works very well - at only 100 Mbit/s. There was simply no way to use 1Gbit/s Ethernet with the thin computer, which pretty much ruled out working across a network with most types of production-quality video.
But now, we're starting to see the first Ethernet to USB 3.0 adaptors. These will allow content creators to hook up their computers to external SANs for collaborative editing and post production. See an example from Presto on the next page.
