But @Fomalhaut is claiming his T5 runs at 10Gb/s, whereas mine doesn't. Are you suggesting that Samsung changed the bridge chip in their T5s at some point?The bridge chip. The Asmedia chip.

I don't think so. Usually they don't change those. But it's probably the firmware. Which is usually upgradeable. . my Strix Arion with ASM2362 has been upgraded last year.But @Fomalhaut is claiming his T5 runs at 10Gb/s, whereas mine doesn't.

So we'd need to know what f/w @Fomalhaut has on his T5. I'm running the latest from Samsung, but my T5 has only run at 5gb/s on my Macs since I've had it, across several f/w versions.I don't think so. Usually they don't change those. But it's probably the firmware. Which is usually upgradeable. . my Strix Arion with ASM2362 has been upgraded last year.
Yeah but if it's a quirk settings. Shouldn't all T5 connects at 5gb/s? . Unless it is using a different or upgraded bridge chip inside the T5.So we'd need to know what f/w @Fomalhaut has on his T5.

Fwiw I don't think it's a f/w issue; I think that Apple have a quirks plist (or equivalent) in place that for some reason downgrades certain USB chipsets to 5gb/s operation, and that they just don't publicise or acknowledge the fact.
It would be good if Fomalhaut gets back with more details of his setup and confirmation of his 10Gb/s.
Yes, this is correct. I'm predicting that when other T5 Mac users actually look at the connection speed in System Report their T5s will all be running at 5Gb/s. If not, my Quirks theory is wrong and the issue is more subtle than we think...!Yeah but if it's a quirk settings. Shouldn't all T5 connects at 5gb/s? .

Yep if there are others with 10gbps link speed. That means it's either firmware differences or just a different chip altogether.Yes, this is correct.

I posted before. My NVME Enclosure is connected at 10GBPS and I get around ~720MBps write.Yes, this is correct.

Here it is on my MBP16. I'm travelling at the moment so can't test on the M1 Mini, but I'm pretty sure it connects at 10Gbs. I may have posted images on an earlier post in this thread; let me check!Any chance you could test and confirm 100%? As none of this is documented/acknowledged by Apple, we're somewhat groping around in the dark trying to nail the issue, so hardware / os details and confirmation via testing are especially useful.
Thanks for that - very helpful. What year is your MBP16 from?Here it is on my MBP16. I'm travelling at the moment so can't test on the M1 Mini, but I'm pretty sure it connects at 10Gbs. I may have posted images on an earlier post in this thread; let me check!
The speed difference between the T5 connecting at 5Gb/s and 10Gb/s is pretty minor - ~440MB/s vs ~520MB/s on sustained read/writes...so you'd probably not notice unless you were looking. This is because the T5 is limited to SATA speeds.I can't recall feeling disappointed by the T5's speed as I was with another USB 3.1Gen2 enclosure than only connects directly at 5Gbps on the M1 Mini.

The MBP is late 2019.Thanks for that - very helpful. What year is your MBP16 from?

The 5Gb/s vs 10Gb/s issue has much more impact when it affects drives and enclosures using NVME disks.
i did ,and they dont give a **** ,even with a serious letter they dont care,problem is i cant really show any absolute evidence.currently im seeking for someone who has made torough tests,better be scientific or known website.lemme know if u find,imma tryna sue them again,that is unnacceptableI would definitely contact Apple about this, because that is seriously misleading. This is early days, though, there still could be some kind of OS-level issue going on.
Pretty good. But it's missing 13% performance compared to an Intel Mac. Or maybe even compared to a Thunderbolt 3 port of a Thunderbolt 3 dock connected to an M1 Mac?Pretty good speed IMO.
I don't know. Don't have either I might go with thunderbolt 3 enclosure if I need the speed. But idk. Should I even wait for USB 4/Thunderbolt 4 enclosure?Pretty good. But it's missing 13% performance compared to an Intel Mac. Or maybe even compared to a Thunderbolt 3 port of a Thunderbolt 3 dock connected to an M1 Mac?
No. Choose if you want 1060 MB/s USB (880 MB/s on M1) or 2800 MB/s Thunderbolt then get an enclosure and SSD that will do that.Should I even wait for USB 4/Thunderbolt 4 enclosure?
Yeh. I was wondering if USB 4 40gbps vs thunderbolt 3 and 4 for external SSD make a difference since all of em are 40gbps.No. Choose if you want 1060 MB/s USB (880 MB/s on M1) or 2800 MB/s Thunderbolt then get an enclosure and SSD that will do that.
The USB option will be much less expensive and the USB limit means you don't need a super fast NVMe.
40 Gbps is 5000 MB/s. We know Thunderbolt 3 can do 4867 MB/s of DisplayPort to an Apple Pro Display XDR but PCIe is limited to ≈3000 MB/s for reasons.Yeh. I was wondering if USB 4 40gbps vs thunderbolt 3 and 4 for external SSD make a difference since all of em are 40gbps.
Tbh thunderbolt 3 enclosure should be fine with gen 3x4 SSDs. The speeds tested on the Mac are usually tested using black magic tho so we dont know the max speed like if you were to test it using AmorphousDiskMark40 Gbps is 5000 MB/s. We know Thunderbolt 3 can do 4867 MB/s of DisplayPort to an Apple Pro Display XDR but PCIe is limited to ≈3000 MB/s for reasons.
If someone can make an enclosure for Thunderbolt 3/4/USB4 that can do more than 3000 MB/s then you'll hear about it here, otherwise you'll have to wait for Thunderbolt 5/USB5.
Should be. But some gen 3x4 SSDs behave strangely in Thunderbolt enclosures (write speed is reduced to sub 1000 MB/s). gen 4 SSDs usually don't have that problem.Tbh thunderbolt 3 enclosure should be fine with gen 3x4 SSDs.
Actually, this YouTube video has a test where the gen 4 SN850 has bad behaviour for write speed (M1 and Intel):Should be. But some gen 3x4 SSDs behave strangely in Thunderbolt enclosures (write speed is reduced to sub 1000 MB/s). gen 4 SSDs usually don't have that problem.
The 2000MBps version is a USB 3.2 Gen 2x2 which has already been reported no supported by apple. Hence the reason why the 1050MBps is almost the same as the 2000MBps version.Seems this issue hasn't been discussed in all those Youtube Videos covering the M1 Pro / Max..
I've got the SanDisk portable SSD, 2TB with 1050MB/s and the 2000MB/s version each. The 2000MB/s version isn't much faster on the M1 Max...
