USB 3.1 The Future, But Slowly


p

So, Was Samsung right in selecting that old Micro USB 2.0 interface for their latest flagship S7 phone?


In many annoying ways yes :-(   Though I am still reluctant to buy any 2016 Smartphone without Type C USB 3.1 interface. In the last 60 days Marcus conducted more USB 3.1 research and the first practical USB 31 testing.


Why USB 3.1?


- Speeds upto 10 Gbps which is over 1GByte/second and fast enough for any disk interface in the current timeframe
- Reversible Type C connector, a joy to use
- Spare pins to allow incorporating other bus standards, principally Thunderbolt, inside the Interface.

Host Adapter Cards

Both my development and Production Workstation now have USB 3.1 Gen 2 PCI cards that I reviewed

USB Type C Adapter Plugs


Your best most prolific and lowest cost source [by far] is eBay.




USB 31 Type C PowerBank




So far only the Xiaomi Powerbank with a native USB 31 Type C interface.  Press release

USB 31 Type C Power Hub




To date only this modest attempt from Anker.  What professionals need is a Type-C only hub.  Then I could run 2 hubs.  One for all my Type-C devices and another for all the rest.

USB 31 Type C Bare Disk Adapter 2.5"




Read my review link, the speeds of the claimed USB 31 interface clearly limited the actual disk.  They were a little faster than my 2014 Orico USB 30 dock, so we made a little progress


USB 31 Type C Dock 3.5 "





At the time of writing only the Startech and Silverstone TS11-C docks exists worldwide!   Prove me wrong, do please.

This product uses a single USB 31 Type B connector, female.

USB 31 Type C M.2 M Key Disk Caddy


Does not yet exist.  It ought to because the USB 31 interface max speed of 10 Gbps is faster than the SATA III or a M.2 B Key



USB 30 Type A Memory Stick



Only mentioned here as a reference because this USB 30 drive is currently way faster than any USB 31 drive that I have found so far

USB 31 Type C Memory Stick

There are Type C connector USB Drives

But I found none with  a 10 Gbps interface.  So at best they are really USB 30 standard products




USB 31 Hubs / Docks





USB 31 Hubs on Monitors

Not found


USB 31 Mini PC


The latest Intel i7 NUC has a Type C connector.  Also consider  
ZOTAC ZBOX MI525



Summary

Right now

- USB 31 Gen peripherals are limited
- And relatively expensive, but still a lot cheaper than Thunderbolt!
- They are not delivering the promised 10Gbps, not even close
- But some are faster than their USB 30 (aka USB 31 gen 1) siblings
- It's basically and enthusiasts game and quite frustrating
- The poor adoption rate is due to the consumer being pretty happy with USB 30 speeds of 5Gbps
