I'm looking to buy a *RELIABLE* NVME-USB external adapter, that doesn't disconnect randomly, can keep up the close to 1GB/s speed.
So far all adapter's reviews contain frighteningly high % of reports of malfunction, random disconnects, sub-par speeds, falling to even under USB 2.0 speeds, etc.
There are 3 main chipsets in the market: JMicron JMS583, Asmedia ASM2362, and Realtek RTL9210 (no product has surfaced with the latter yet, so no REAL reviews, experiences yet UPDATE: it is on the market already).
Also ASUS has a new product, ROG Strix Arion, but there isn't enough feedback about it yet, and I mean real life feedback not just being able to run a few benchmarks, but real stress test to see if the device (adapter) can keep it up, without disconnecting or slowing down hard.
I would really appreciate any feedback from those who have GOOD experiences during stress-tests, like tons of random 4k writes with a stable speed, cloning 100's of GB-s at a stable high speed close to 1GB/s.
I know SSD's very well, so please stick to the point and don't start to educate me on how their speed falls after some writes, etc. I'm aware and this is NOT the point.
You can help if you can point me to a STABLE and RELIABLE NVMe-USB-C adapter that WORKS as expected.
Thank you in advance!

JMicron JMS583 has a compatibility problem with KIOXIA BG4
which causes data corruption

You can read about it here

I also verified it on two BG4's and two different JMS583's

Thanks Shonky. Should we assume you also successfully tested these same drives with a different bridge chip (not Jmicron) ??

More details of your investigation would be nice.

Thanks.

I just verified goughlui's finding with the JMS583 as i have 4 x BG4's to test
goughlui confirmed that RTL9210B is fine with BG4's and posted screenshots in the link i posted
so didnt feel the need to verify that

JMicron need to post a firmware fix for KIOXIA BG4's with the JMS583

Thanks. I hope a fix comes soon.

Is it generally better to get a M.2 SSD instead of SATA now because of HMB and dramless models for large capacity cheaper SSDs for storage purposes?

Also are cheap ugreen/orico m.2 usb enclosures decent? Don't know the difference in the models.

Motherboards now have 3 or 4 M.2 slots nowadays so I'll be switching to M.2's.

Is there a question buried in there somewhere, or did you just want to post what you've decided?

Sata is slower than nvme. Everyone knows this.

Ugreen and orico both make decent enclosures. If you want specific info, you'll have to be more specific on the exact ugreen or orico device.

There were 2 questions. I haven't been keeping up with the news so I wanted to ask even if "everyone knows this".
I provided links to 3 devices.

Is this error reproducible on other Kioxia SSDs?

Try it
I have BG5's and BG6's but cant be bothered testing
as i dont want to go buy more RTL9210's to replace the JMS583's if there turns out to be problems
i doubt it though the controller is built into the nand on the BG4's BG5 is external BG6 is a SMI2268XT

I have too many JMS583's to go testing too indepth..

Wow. I'm specifically interested in the xg6, which I have, but haven't bought a enclosure for yet.

XG3,XG4,XG6 are fine in all enclosures its the dramless models that get problems in certain Enclosures
For example WD SN740 gets IO resets on pc reboot on one chipset cant remember if it was ASM2364 or RTL9210B
i think it was aleviated with a firmware update on the SN740's at some point cant remember
Samsung PM9B1 gets an io error on reboot also on one of them cant remember which
BG4 you know about with JMS583
