Default Anyone know of a NVMe USB3 carrier?

Pop a Samsung 960 inside that guy and you'd have a
Flash drive to die for!

Â*Â*Â* "Ganesh

Â*Â*Â*Â* Would be a risky buy. Very few NVMe SSDs (actually none come
Â*Â*Â*Â* to my mind) that can operate below the 4.5W limit of USB 3.1 Gen 2.

Â*Â*Â*Â* Only TB3 ports are guaranteed to supply higher power (or the
Â*Â*Â*Â* Gen 2 port must support higher PD profile)
Â*Â*Â* "

Maybe a USB C connector on the host system could do that ?

Where the risk might come in, would be when cobbling
together a regular USB3 connector to the USB C.

Since the NVMe runs at half speed, that may have
a small effect on power consumption.

Yikes!

https://en.wikipedia.org/wiki/USB-C#USB_Power_Delivery

Â*Â*Â* VBUS and GND provide 5 V up to 900 mA, in accordance with
Â*Â*Â* the USB 3.1 specification. A specific USB-C mode may
Â*Â*Â* also be entered, where 5 V up to 3 A is provided

For the Samsung 960:


https://www.samsung.com/semiconducto...nsumer/ssd960/


Â*Â*Â* AVERAGE POWER CONSUMPTION
Â*Â*Â* (System Level)3)

Â*Â*Â* Typ. 5.1 Watts (512 GB)
Â*Â*Â* Typ. 5.3 Watts (1024 GB)
Â*Â*Â* Typ. 5.8 Watts (2048 GB)

5.8 WÂ* /Â* 5 Volts = 1.16 amps.

So, a C connector would be required.

Sure hope I don't have to clone one of these pretty soon!

Just checked the specs on the
Siig JU-P20A12-S1, USB 3.1 2-Port PCIe Host Adapter

Power output:

Type-C: Up to 3A
Type-A: Up to 900mA

And it comes with a Molex connect for hooking directly into
power supply

No Windows 7 drivers though.

Oh and I also noticed on the Wikipedia article I linked to
about that the C cable also has to be rated for the
higher current.
