The SSD Review published a review on the ASRock Z97 Extreme6 Motherboard Capable of Supporting M.2 (NGFF) SSD With Speeds Up To 32GB/s

A quote from the article:

We are happy to report that things have changed significantly with new Z97 ASRock boards. Not only do all but one contain a native M.2 Gen 2 x2 connector, but more importantly, the Extreme 6 contains what ASRock terms as an ?Ultra M.2? built on a PCIe Gen 3.0 4 lane base. This provides for up to a whopping 32GB/s transfer speed from a single M.2 SSD. Is that future proofing things or what?
