After proposing SSD controllers, VIA made news again by announcing a new controller, the VL716. This is a USB / SATA controller, the type found in enclosures for external hard drives. This controller, however, has the distinction of being the first to have passed the certifications USB Type-C.
Asmedia already provides for a while USB 3.1 / SATA solutions like ASM1352R we use during our tests motherboards, but it was obviously not certified Type-C (although our test case to be provided). In practice, we met with him a number of disconnections for use in Windows.
The new VIA controller is managing a side USB 3.1 10 Gbps, with support BOT and UASP transfer protocols (see this article for details), and the other SATA 6 Gbps.
The chip is relatively small, 6mm side allowing to create compact designs. VIA does not specify how the chip handles standard USB Power Delivery. Technically, the presence of the USB Type-C requires management at least to the minimum standard.
The power of an SSD (or a 2.5-inch hard drive) will not cause problems, 5W provided by all USB connectors enough, but discs 3.5 inches may require a higher power. As it stands, hard to tell what is actually managed. The illustration provided suggests that one should find this chip in housings 2.5 inches.
If the SATA 6Gbps is limited in practice from 5 to 10 Gbps USB side should be quite beneficial. As we have seen in this article, USB transfer protocols as the BOT mode are particularly ineffective, and UASP drivers Microsoft does not shine by their speed.
