Question Extremely slow speed on new Sandisk Exterme Portable SSE in Windows

[dmaker]

Hi all, I have an MSI Raider GE75 10SFS According to the MSI spec sheet, it has the following ports:

1x Type-C USB3.2 Gen2
2x Type-A USB3.2 Gen1
1x Type-A USB3.2 Gen2
1x RJ45
1x SD (XC/HC) Card Reader
1x (4K @ 60Hz) HDMI
1x Mini-DisplayPort

Yesterday I picked up a Sandisk Extreme Portable SSD (SDSSDE61-2T00-G25) When I tested it at work on my 3 year old Macbook Air, it tested quite high....I believe it was 3500 MB/s or so. But when I connected it at home and ran a CrystaldiskMark, I was getting 40 MB/s
That is hugely disappointing. I used the same cable as I did at work as well. And given what ports are provided by this model, it's not as if I could have made a mistake. There is only one USB C port on the laptop.

Has anyone seen this before and might have some helpful suggestions?

Thank you.

I have tried this slot with a SATA SSD in a USB3 enclosure and it is only detected as USB 2 as well, but this drive works fine on 3 other systems. I have tried multiple cables (including the one that came with it), and no usb3 device is being detected properly.

Not going very well with MSI support. It has taken a week for them to look at the screenshots and system reports to acknowledge that yes it should be detecting it s USB3, but it is not. And that I should take it to a local MSI service center. Which is a two hour drive from my house.
Their support sucks.
