Can a USB-C 3.2 Gen 2 drive be used with a MacBook Pro M1 Pro? And if yes, do the speeds just max out at the Macbook limit?
You're asking if the new M1 Macs supports USB 3.2 gen 2x2? I don't think so.Anything new on that topic? Would really like to purchase the SanDisk ExtremePro 2TB with 2000MB/sec for my new MacbookPro.
I don't have an M1 Mac to test Apple Silicon drivers.How did testing this go?
I think the answer is yes, and it will max out at around 1,000MB/s.Can a USB-C 3.2 Gen 2 drive be used with a MacBook Pro M1 Pro? And if yes, do the speeds just max out at the Macbook limit?
I have been looking at this SSD but unfortunately I think it will max out at 1,000MB/s on M1/M1 Pro/M1 Max.Anything new on that topic? Would really like to purchase the SanDisk ExtremePro 2TB with 2000MB/sec for my new MacbookPro.
Is such WD My Passport (USB3.2) a "USB 3.2 Gen 2x2" which supports 20 Gbps = 2,000 MB/s?The computers :
iMac 24 M1 2020
MacBook Pro M1 Max 2021
The SSD :
WD My Passport (USB3.2)
It is USB 3.2 Gen 2 which tops out at 10 Gb/s (under 1,000MB/s).Is such WD My Passport (USB3.2) a "USB 3.2 Gen 2x2" which supports 20 Gbps = 2,000 MB/s?
Just had this exact drive arrive and can confirm it only connects at 10gb/sec, topping out at about 900MB/s.Anything new on that topic? Would really like to purchase the SanDisk ExtremePro 2TB with 2000MB/sec for my new MacbookPro.
I am repeating myself, but this Amazon review is a helpful summary of the USB specs. USB 3.2 Gen 2x2 is optional under the USB4 standard, and cannot coexist alongside Intel Thunderbolt 3 controller. I’m glad I did some research before making a purchase, but it’s been very confusing.Just had this exact drive arrive and can confirm it only connects at 10gb/sec, topping out at about 900MB/s.
I’m a bit puzzled because the Apple site says the 16MBP has both TB4(40gb/s), and usb4(40gb/s)…which should be able to hi the advertised SSD speed of 2000 MB/s.
Feel a bit misled or confused. Maybe both at this point.
I’m with you to the point where the Apple site states 40gb/s usb4 ports x3.I am repeating myself, but this Amazon review is a helpful summary of the USB specs.

[emphasis mine]For giggles I looked the usb 4 spec up. USB4 40 Gbit/s Transport does state optional, but since the Apple site does say 40gb/s, I don’t see why the setup cannot hit advertised speeds.

So what I'm seeing is that the new M1 MBPs support USB4 (Gen 3×2- 40 Gbps). By USB4 standards, it supports backwards compatibility of USB 3.2 (10Gbps), but not USB 3.2 (Gen 2x2-20Gbps). I don't honestly know why 3.2 2x2 exists and is not a requirement for USB 4.
That is incredibly confusing standards implementation (USB-IF) & unclear marketing (Apple).
Yeah I showed the results I got in the video.From reply 18 above:
"...I picked up a Samsung T7. It's USB-C 3.2 and suppose to give me 1000mbps read/write
I tried it on my 16" 2019 MacBook Pro, 14" base model MacBook Pro, and my gaming pc. None of them hit those speeds."
You won't get 1000MBps. That's a "theoretical limit" and I doubt that anyone ever sees it.
You MIGHT get upwards of 900MBps.
You're more likely to get reads of 800+MBps and writes in the 600-700 range.
Yep, I hear ya. Its not that it isn't playing well, its working as the standard implies...but the standard is too complex (USB shouldn't be), and the vendor marketing is made to sell.There is a much larger tech world beyond our relatively tiny Apple bubble. Just because something doesn't play well with Apple doesn't mean it doesn't work exactly as intended with far more technology devices.
But I certainly agree that "standards" should be standards and not require consumers to "just buy it and test" to see if something will work as marketed.
You would get better numbers (1060 MB/s) with an NVMe in a USB NVMe enclosure.Yeah I showed the results I got in the video.
I'm just bummed out that my 2 year old intel MacBook got better speeds than my new 14".
