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.

Sandisk said best case go up to 1050MB/s

windows 10 or 11? latest chipset driver?

Windows 11. I will check MSI for any updates, but I think everything is up to date.

But I am only getting 40 MB/s

What I also don't understand is that in USB Device Tree Viewer, I see two Host Controllers...Intel and Nvidia. Intel shows port 4 as USB 2 while Nvidia shows port 4 as USB 3

Under Nvidia Xtensible host controller:


=========================== USB Port4 ===========================

Connection Status : 0x00 (No device is connected)
Port Chain : 2-4

SupportedUsbProtocols : 0x04
Usb110 : 0 (no, port not supports USB 1.1)
Usb200 : 0 (no, port not supports USB 2.0)
Usb300 : 1 (yes, port supports USB 3.0)
ReservedMBZ : 0x00


I have never really looked at this before, so I am not that familiar with what I should be seeing here. There is only one physical USB C port (pretty sure. I can check later when I am home from work).

Are you looking at the Sequential or Random results? What Queue depth are you looking at as well. For example I only get 37.94MB/sec on Random 4k Queue depth 1 on my internal NVMe drive. However, for Sequential at the same Queue depth I get 1335MB/sec.

I just ran Crystaldiskmark with the defaults:

Not sure how to paste a screenshot here (maybe not possible?)

I got 40 Read 43 Write for SEQ1m Q8T1 .......lastly, 13 Read and 18 Write for RND4K Q1T1

So, it looks like it's a USB 3 port but it is being detected as a USB 2 port...yuck.

HWinfo shows USB Version Supported: 3.00 (Connected to a USB 2.00 Port)
USB Device Speed: USB 2.0 High Speed

But this drive performed way above USB 2.0 speeds when connected to my Macbook. So it must be a software issue, not a port issue....

It must be something specific to my MSI laptop. I just connected the drive to my work PC via the USB3 TypeA adapter that came with it and I am seeing typical USB3 speeds, i.e. 450 MB/s Read. I tried the same TypeA adapter on a USB3 type A slot on the MSI laptop and the speeds were still 40-50 MB/s

Good idea, Bob.
I connected a USB3 SATA SSD and it was detected properly as USB3. It just seems to be this Sandisk drive that this MSI laptop won't detect as USB3.

I did get a response from MSI support. They acknowledge the facts of the issue--my port is USB3.2 Gen 2, the SSD is USB3.1 so they should be working and that my bios and EC are both up to date.

That is good. We'll see if maybe they can provide a bios update or something.

You mention the bios and ec.
Is the chipset up to date?

As far as I can tell. Unless there is a specific update for the extensible host controller that is not listed on MSI website or something. I made sure all of the drivers and firmware matched the manufacturer support site.
