You wouldn't happen to have a link?

I have been scratching my head trying to figure out how to
clone an NVMe drive when the motherboard only supports
on drive.

It looks like it is B keyed, rather than M keyed.
It expects to run in SATA mode. A device that works
NVMe only, probably won't fit (keying).

It would probably be quicker to just look through the
Asmedia chip specs page and see if they make an NVMe one,
than slog through the customer reviews for each of these
things.

Rats! Thank you anyway.

There's one here, but with so little tech info, I couldn't
buy that, even as an impulse buy. It only lists compatibility
with XP941 and no other drive. Even if I could get a sniff
of the chip used, I could figure out whether it's a "trick" or
a legit converter. Most of the other products eventually admit
they need B-key.

Even if that had customer reviews, it would be better than nothing.

And while I could find a reference to "converting M.2 to U.2", there
is no U.2 to USB3 adapter either.

I eMailed them asking if it worked with an NVMe drive. I will
get back.

Hot off the presses.

https://www.tomshardware.com/news/jm...ssd,37264.html

It's shown demonstrating 1GB/sec over USB3.1.

Toms will apparently be doing a review of it
at some point.

JMicron has spun off a company called Maxio Technology
or similar, and it's hard to say which company that
item comes from. Maybe if Toms has a close-up picture
of the PCB, the logo will be visible.

JMicron was the company that made a few SSD controllers
that used to "stutter". And that kinda ruined their
good name. That's why the details of the review
will be important, to see if they learned any lessons.

I only discovered a reference to that item, when
Googling on Maxio Technology to find out more about
the company, and just how much of a rebranding
exercise it was.

*******

I saw another curiosity yesterday. I was looking
to see if a Laplink cable is available for USB3.
That would be a USB3 cable with a "blob" in the
center, for transferring files directly between
two PCs.

It turns out Prolific makes a chip for that. The
chip has firmware supporting four protocol
variations. The one using WinUSB protocol
seems to be the popular one, and Linux has
a driver too.

The Laplink concept is a simple one. First, it
violates USB premises, by connecting two hosts
directly to one another. (Also violates the
grounding strategy - both PCs should be on the
same power strip, if they're desktops. A laptop
likely floats and wouldn't be an issue.)

The Laplink idea uses two FIFO queues, one in
the transmit direction, one in the receive
direction. One side pushes, the other pulls.
Each side thinks it is talking to a Peripheral,
rather than a host. The FIFO queues help hide
the details.

The USB3 version transfers at around 50MB/sec or less.

It turns out, the chip has a low end 8 bit
microprocessor inside. For what reason, I don't
know. I sure hope it isn't in the datapath...

In any case, it exists. But it isn't clear
whether it belongs in your "cable bag".
