Re: I don't get it.
It's an m.2 connector, most mid-range or above motherboards come with the ports now. They come in either PCIE or SATA formats, and the PCIE versions can be a _lot_ faster. There aren't many PCIE drives out yet though. This one looks pretty tasty, depending on price and if you can get them retail.
EDIT: also, that article is from 2010, so yeah, a bit behind the times..
