Anyone have a good PCIe USB 3.1 card they like?

They do make an M.2 enclosure for USB3.1 Rev2, and that can go just a wee bit faster 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. |

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). https://www.amazon.ca/StarTech-com-M.../dp/B00T8F298Y 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.

Paul 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. http://eshop.sintech.cn/m2-ngff-pcie...se-p-1067.html 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. Paul |

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". Paul |
