Default Anyone know of a NVMe USB3 carrier?

Hi All,

Anyone know of an NVMe (not M.2 SATA) USB 3.x carrier?

Many thanks,

The product brief on the chip is here.

http://www.jmicron.com/PDF/brief/jms583.pdf

It doesn't waste a thing, in that it only
connects to two lanes of four on the M.2 .

I presume this is a bandwidth balance, so a Samsung
that runs at 2.5GB/sec, well, the bridge USB3.1 Rev2
side can only do 1GB/sec anyway. So they cut the
lanes in half, to a theoretical ~2GB/sec. And at the
usual PCIe efficiency due to buffer size, that
gets them 1GB/sec.

The sheet mentions TRIM, so there must be some
kind of passthru in the OS driver.

The block diagram shows a "RISC" processor inside it.
Makes you wonder what IP they bought for that. Not
your usual 8085.

It looks like a sweet design.

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

"Ganesh

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

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

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

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

For the Samsung 960:


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


AVERAGE POWER CONSUMPTION
(System Level)3)

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

5.8 W / 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.

But that's the whole "C thing". Playing the
roulette wheel when getting a cable. And discovering
the hard way, it isn't quite right.

That's why we have addin USB3 type cards, so if
you ruin one, it might not cost you a motherboard.

I don't have any USB-C stuff here at all. No adapter
cables. Nothing. All I have is Type A USB3 Rev.1 for
the most part. My Rev.2 card is the first Rev.2 item,
and it has Type A connectors.

(USB.org knows how to run an operation)
