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!

The part about "Always using the latest firmware version" - is it updateable?
how does one update it?

I bought this nvme: https://www.amazon.com/dp/B0BXSYK91G (iDsonix M.2 NVMe PCIe SSD Enclosure )
idVendor 0x0bda Realtek Semiconductor Corp.
idProduct 0x9210 RTL9210 M.2 NVME Adapter
bcdDevice 20.01
iManufacturer 1 Realtek
iProduct 2 RTL9210B-CG
iSerial 3 012345679039

and running into weird issues where it goes to read-only mode after awhile.
Tried 2 different computers.
Have you also tried using a different drive in the enclosure?

Also might be worth checking with a different cable. I've seen cables cause some pretty weird symptoms, and lots of enclosures come with pretty flakey cables.

https://www.amazon.com/dp/B0CFXS4KNC - orico nvme+ssd - DO NOT BUY
https://www.amazon.com/dp/B0BXSYK91G - iDsonix M.2 NVMe - DO NOT BUY

^ above enclosures didnt work for me in linux. both showed up as RTL9210B-CG and ended failing after about 2 minutes of rsync.

then got this orico 40Gbps usb4 enclosure for 40$ from aliexpress: https://www.aliexpress.us/item/3256806583353849.html - it worked without any f-ing problems with the same exact nvme drive. Chip comes up as ASM246X in fedora 41 linux

fwiw - I dunno if it was those enclosures fault or linux UAS (blacklisting UAS and forcing usb-storage for those nvme also worked - but who's got time for that).

Hello! This is my first post here.
I was wondering if anyone found a reliable M.2 NVME enclosure that works for Linux? And especially with TRIM support? (And of course S.M.A.R.T is a nice bonus)

I've looked at IB-1817M-C31, which was linked from Arch Wiki. However there appears to be a lot of complaints with it.
Looking elsewhere for enclosures with chipset of JMS583 seem to indicate not all enclosure with such chipset supports TRIM, and also there appears to be a lot of complaints on reliability which is essential given it's going to be my boot drive.
One blog (https://tisyang.github.io/post/2023-05-25-linux-usb-storage-safe-shutdown/) seem to indicate RTL9210B is supported, yet I'm not sure if that's true for all enclosures with that chipset.

Can anyone recommend some enclosures they confirmed work on Linux and have TRIM?
Thanks!

(Sorry for my English)

Ah, It appears like I misread one of the forum post and interpret it as that some enclosures wouldn't work even with same chipset... Sorry about that...
So in theory, most enclosures that states TRIM support should work on Linux one way or another with a little fiddling?
