Slow USB-C NVMe ssd performance on M1

[ca$hman]

Thank you. Via Amazon, it looks like this is the same Thunderbolt: https://www.amazon.com/Certified-Ne...+WD+SN750&qid=1615052255&s=electronics&sr=1-7

I'm searching for what controller chipset this Thunderbolt enclosure uses. Running System Report, does any info show in Thunderbolt/USB4 Bus 0:

[Certified] Nekteck 480GB Thunderbolt 3 SSD NVME Hard Drive | eBay replaced the 480GB SSD with the 1TB WD Black.

Thanks for your info. Is the replacement easy to do? Is the original 480GB SSG in 2280 form?

In case it helps anyone...

I have purchased this Fideco M.2 NVME Enclosure-USB 3.1 Gen2 (10Gbps) £30
Upgrading from my 10yr old Mini I didn't need anything special just better newer storage so purchased 2 of these for a general drive & back up as good value and reasonable reviews for the price. (its not going to be working hard)

On testing with the Blackmagic program Im getting around 800MBs (6.5GBs) on both drives formatted to APFS & Encrypted
Samsung 970 EVO Plus & WD Blue SN550
The Fideco NVME Enclosure has the Realtek RTL9210B Chipset.

Not bad value, but its always nice when things are a little closer to advertised speeds isn't it!
Not that Im likely to notice compared to my previous setup

I should've checked this thread before buying my enclosure. The enclosure I bought is the Asus ROG Strix Arion a USB 3.2 Gen 2 (10Gbps) enclosure. I am very disappointed with the speed when connected to the Mac Mini M1. It can only achieve approx 65% of the speed I expected. However, when connected to an intel MBP 16" it produced the right expected speed (approx 900MB/s). So what's the difference?

Updated to 11.3 and it's still not resolved.

I've just got my M1 so also seeing these issues too with the NVME enclosure with the Jmicron controllers.

Glad I stumbled across this thread before I looked to give Apple a call, looks like this is my hardware.

What I have found as I have a few of these drives is that using ExFAT significantly improves the performance, however at the expense of privacy. Screen shots of the same drives running on my 2018 MBA for comparison

One screw to open the case. One screw to loosen the ssd, take out the old ssd and plug in the new ssd. And fasten both screws again.

I look different enclosures and almost all are JMS853 chipset?
example this: https://www.amazon.co.uk/gp/product...0?ie=UTF8&psc=1&tag=macr0e-21&geniuslink=true

So what is good enclosure with the Realtek chipset?

I look for enclosure + 2tb NVME about 250 euros price so can you recommend something?

I've now received my Orico M2Pv-C3 (RTL9210 based) enclusore and can gladly report back that it seems to have solved the problem, for me at least.
I now get 700+MB/sek both read and write on a APFS ENCRYPTED volume on initial benchmarks, which previously with the JMicron Chipset was approx 100MB/sek.

I guess I got lucky. Not knowing about these chipset issues, I just happened to order the Orico M2PV-C3 from AliExpress and it came with the Realtek RTL9210 chipset.

Have you tried the drive with USB-A? The reason I ask is that WD SN750 can draw over 5 Watts power on its own.

The 2 TB WD SN750 is currently only slightly more expensive than the slower 2 TB WD SN550 locally, but the SN550 uses considerably less power. I'm thinking for USB-C it probably wouldn't make much of a reliability difference, but it could make a difference with USB-A on some systems.

BTW, I currently don't have a Windows machine, so I have no way to update the Realtek firmware if necessary. I only bought it last month though, so hopefully it has a recent firmware. Also, I only have Intel (and PowerPC ) Macs, not M1.

So they key here is - buck up for an Thunderbolt 3 enclosure/fast drive it sounds like?

I wonder if part of the issue is related to power consumption. Thunderbolt 3 should guarantee adequate supplied power.

Another option would simply to get a Samsung T5 or T7. The 2 TB model T5 often goes for less than CA$250 in Canada so even including VAT I'm thinking it should be well under 250 Euro.

I can back that up, my Nekteck enclosure with a WD SN750 does a whopping 2319MB/s write and 2541 MB/s read performance with my MBP M1. Now using this an external boot disk. Works just fine!

I bought the SN750, the firmware number is 112000WD, the box uses ACASIS, JHL7440 master control, my M1 max test speed is 1200MB/S for writing, 2700MB/S for reading, very bad data, online search means that WD has modified the chip , And the SSD speed limit, there is no corresponding firmware to solve this problem.

Well that is a bummer if true. Wonder why they speed limited the SSD? What external enclosure are you using?

My box is an ACASIS TBU401 usb4.0 external hard disk box. I choose the brand and model of the hard disk. I had the same problem before about the speed limit SN850. Finally, WD provided an upgrade firmware to solve the speed limit problem, but the SN750 has not solved it yet. method

I am using a Necteck enclosure that uses Intel DSL6340 controller giving me the high speed reading/writing result.

I try two different Thunderbolt 3 enclosure with same KingS 1tb NVME drive and my imac 24 m1 2TB the results are very bad

first one is internal mac drive very fast:

second is jeyi T3 enclosure

and last wavelink TB3 enclosure

at this point I don't know if it's the nvme drive that it not good or the enclosures
