Hi all,

Seeking a fast external NVME storage solution for my iMac 2020 i7.
Looking specifically at the WD black SN850 1tb SSD but unsure which enclosure will provide the best performance.

Any suggestion would be greatly appreciated.

Many thanks
Neil

USB3 -- reads around 430MBps.

USB3.1 gen2 -- reads around 830MBps.

Thunderbolt3 -- reads around 2,000MBps.

I was on the Apple website and they recommended this one;


I liked it so much that I bought another one. They're blazingly fast :)
Just purchased one.....what NVME did you purchase?

I bought the Inland Platinum 2TB. Incredibly fast...

USB3.1 gen2 -- reads around 830MBps.
Thunderbolt3 -- reads around 2,000MBps.
Properly working NVMe and enclosure should give these near max numbers:
USB 3.0 -- reads around 455MBps.
USB 3.1 gen 2 -- reads around 1000MBps.
Thunderbolt 3 -- reads around 3000MBps. (easily seen with a gen 4 NVMe; gen 3 NVMe's usually give less).

Careful with that purchase. I had a glotrends nvme to usb-c enclosure that was fine, gave me about 950 mb/s read and write. Until I upgraded to Big Sur. Became unusable. Tested on more than one device. Worked even worse on m1. Something to do with that particular controller and Big Sur I think. I switched to a Samsung t7, getting about 800 mb/s read and write on m1. Not as good as I should get, but it's acceptable for now.

Two questions:
Do they have a fan or otherwise actively cool?
Do they throttle at higher temperatures?

Thanks....

Well I have 1 OWC T3 Envoy Express,1 SABRENT T3, and 4 ORICO T3 enclosures....and the Orico are the best for me. My startup disk is a Samsung 980 EVO Pro 2TB in one of the ORICO T3 enclosures. Very very fast!

Sabrent has both Thunderbolt 3 and USB toolfree enclosures.

But if you are going to boot from it, I would stay away from DIY NVME enclosures all together simply because of possible compatibility issues.

For booting, the Samsung X5 is fast and reliable, it works great for booting my 2019 iMac.

Well in the end & following quite a bit of research I decided to cancel the Trebleet enclosure & instead opted for the Orico along with a WD SN550 2TB which I got a really good deal on. Both arrived today & am pleased with the combo, giving a stable write speed of 1800 and read around 2300 so for my needs this is perfect.

Which Orico Thunderbolt 3 enclosure are y'all talking about? I can only find Orico USB 3.2 NVMe enclosures on Amazon and one on Newegg that ships from China.

On their website, they say it will run hot, but I now have two of these and neither one runs hot. I just checked again now, and again neither is at all hot. I have them sitting on top of another aluminum enclosure so maybe they are using it as a heatsink?

It runs quite warm when in heavy use.
I also encountered 2 issues yesterday - whether they're related to the T3 enclosure / SSD I'm not sure but I had a freezing iMac dock bar (first time this has happened) & a drive disconnect (at the time of the disconnect I was inspecting the enclosure so might not have been not securely attached, i'm not entirely sure). I have tried replicating the issue by looping BM for 20 mins & all seems OK.

I see, thank you. Doesn't seem to be available in the US at the moment.
PS: running hot is a good thing because it means it is actively dissipating the SSD's excess heat. If it were cool to the touch, that's when you're in trouble.

Yeah they are out of stock here in NZ. My ORICO T3 enclosures look a little different:


They do run warm.....I have them sitting on a kitchen cooling tray :)

I just wanted to share that this thread(and forum) was very helpful while I tried to find a compatible enclosure for my new Crucial P5 (https://www.amazon.com/Crucial-NAND-NVMe-Internal-3400MB/dp/B087QRVVVH). I first tried a uGreen CM400 (https://www.amazon.com/UGREEN-Enclosure-Aluminum-External-Compatible/dp/B08DNR22Q7), but it didn't work, hung up, didn't initialize at one point. BUT, someone suggested a MOKiN (https://www.amazon.com/Enclosure-Adapter-Tool-Free-RTL9210B-External/dp/B08DCLPYGK) and I'm happy to report that it worked today. I'm a bit disappointed in the speeds I'm getting, but it's still double what I was getting with my old SSD, so I've got that going for me. Thanks!

It's a dual setup. Have you used it with both NVME slots filled? If so, how is the performance with both?

Thanks for the recommendations for the Orico. Just got mine, using with a WD SN750 500GB on an M1 MBA. This was taken with it connected to a Caldigit TS3 hub and about 50% loaded.

Did you insert the supplied Silicon Thermal Pad when assembling? This is not mentioned in the instruction leaflet. Thanks.
