Latest Skylake chipset Gigabyte Brix

Includes
Thunderbolt 3 through USB C port :
marked as USB 3.1 as this USB C port supports USB3.1
https://thunderbolttechnology.net/blog/thunderbolt-3-usb-c-d...
As in the diagram a few posts above
Thunderbolt 3 supports PCIe 3.0
=
lower latency audio, two 4K displays, 100W to power charge devices,
10Gb Ethernet, external gaming card, daisy chaining six devices & USB 3.1 :
all from one USB C port.
Data transfer:
If a Thunderbolt 3 device is connected we can get *theoretically* 5GBytes/s (40Gbits/s) data transfer.
If a USB 3.1 device is connected we can get *theoretically* 1.25GBytes/s (10Gbits/s) data transfer.
Currently closest to 5GB/s data transfer are NVMe SSD that use PCIe 3.0 interface.
Eg Samsung SM951 M.2 PCIe 3.0 NVMe NAND SSD *upto* Read 2150MB/s, Write 1550MB/s.
&
Intel's XPoint Optane SSD (Pete mentioned this) writes data *upto* 2GB/s

Sloooow SATA3 interface VS NVMe interface
Difference between NVMe
NAND SSD & NVMe
Intel XPoint Optane SSD

(Difference compared to SATA SSD would be far starker).
Whilst being
"1000x more durable than NAND SSD"…
(One thing to bear in mind .... there are NVMe that use sloooow SATA 3 interface).
::::
Intel Skylake chipset :
Tablets, Ultra Notebooks, Ultra Small Form Factor computers as Gigabyte Brix
should start seeing Thunderbolt through USB C port alongside internal PCIe NVMe either NAND or Intel XPoint Optane
(Some high end tablets, Ultrabooks already have PCIe NVMe SSD).
For audio :
Recording gazillion tracks at low latency, streaming mega samples (Hans Zimmer) more of a breeze internally as well as externally
Once if when Thunderbolt3 audio cards & Thunderbolt 3 NVMe SSD external storage devices appear.
withOut requiring power supply.
(Thunderbolt 2 audio cards already available
eg. Apogee Symphony, Focusrite Clarett Pre & Saffire Pro, MAudio DeltaBolt 1212, Motu 828X, RME Fireface, Universal Audio Apollo Twin Solo),
