Flash drive Kingston DataTraveler microDuo 3C: review and testing

Meet a flash drive Kingston DataTraveler microDuo 3C, which is one of the first storage devices, equipped with a new connector USB 3.1 Type-C.

Kingston DataTraveler microDuo 3C

This standard was approved in summer of 2013, but the first versions of its practical implementation appeared recently. The most famous among them are the Apple MacBook, the second generation of Chromebook Pixel from Google, as well as tablet Nokia N1.

There are two generations of USB 3.1, which differ in capacity: for USB 3.1 Gen 1 it is a 5 Gb/s, and for USB 3.1 Gen 2 it’s 10 Gb/s. The second generation is quite popular now. Also, USB 3.1 interface can transfer power up to 100 W.

The appearance of the new standard means the arrival of the new connector USB Type-C, which in terms of size is little more than the usual micro-USB (Micro-B). However, if in the characteristics of the device you have met references about support USB Type-C, it is not necessary to automatically hope the bandwidth 10 Gb/s, as this format can realize not only USB 3.1, but also USB 3.0 and USB 2.0 which have a much lower speed capabilities. For example, the above mentioned Apple Macbook and Google Chromebook Pixel have ports USB Type-C with a capacity of 5 Gb/s, well, a manufacturer of tablet Nokia N1 decided to limit the features of USB 2.0 with a bandwidth of 480 Mb/s.

USB Type-C has an important advantage: as the well-known Lightning from Apple, it can be connected by every side, as it is a balanced connector. In contrast to micro and mini-USB, where the contacts are in a certain order, which did not allow any connection to the other side, in USB Type-C this problem was solved by a simple duplication of contacts. According to the diagram above, contact groups are wired mirror that allows you to connect the device "upside down". Besides the design must withstand 10 000 connections, which makes it more reliable.

Another analogy can be drawn between USB Type-C and Thunderbolt: both of them are capable of transmitting not only data, but also video. That is, the USB Type-C can also be used in alternate mode, because it has four pairs of high-speed Super Speed USB, two of which can be allocated for the standard DisplayPort, which is enough to transfer the image in the resolution of 4K Ultra HD.

Of course, the user faces with a compatibility problem, because USB Type-C is a new format, so it is not directly compatible with other types of connectors. However, the manufacturers have taken care of this by providing a very wide range of different adapters. Some of them, for example, Kingston released drives with two ports: USB Type-C and more common USB Type-A. And this flash drive will be described in this review.
