Ever wondered why nobody made a SATA-Express SSD? We guess it's probably because of its IDE-sized connector. The SSD industry is turning its attention to other connector standards, such as M.2 and the newer U.2 (formerly known as SFF-8639). The U.2 is essentially a cabled M.2 connector, designed for drives in more common form-factors, such as 2.5-inch. The connector itself is more narrow, although it has the same pin-count as M.2, and the same bandwidth (up to 32 Gb/s with current PCI-Express standard).

ASUS debuted the connector on its flagship Maximus VIII Extreme motherboard, but MSI doesn't plan to be left behind. MSI released a new accessory that converts M.2 slots into a U.2 port. The MSI Turbo U.2 Host Card has wiring to support 32 Gb/s physical layer. The card could be included in MSI's upcoming high-end motherboard, and looking at the way it's branded and packaged, it could even be sold separately. One of the first U.2 drives is Intel SSD 750 in its 2.5-inch avatar.
