Anyone know of a NVMe USB3 carrier?
Hi All,
Anyone know of an NVMe (not M.2 SATA) USB 3.x carrier? Many thanks, -T |

Thank you! https://www.tomshardware.com/news/jm...ssd,37264.html https://www.aliexpress.com/item/JEYI...874418125.html 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. Paul |

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

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. |

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) Paul |
