SEI12 1235U Bad SATA Port? Slow/Hanging 2.5 SSD

sirjmann92

Hello,


I'm having a problem with my Beelink SEI12 w/ 12th gen Intel 1235U CPU (16GB/500G model). I purchased a 2.5 inch 1TB Samsung 870 EVO SSD and connected it. In Windows, I'm not able to complete a performance benchmark normally, it takes an extremely long time. I also can't complete a Diagnostic Scan in normal time. Write speed of the drive in Windows is 1-3MB (!?) when the tests complete (should be ~530). In Linux, on the same PC (dual boot) I get ~280MB, which is also slow but at least seems stable. In Windows, the drive "hangs" when doing a benchmark at exactly 3% every time. Creating volumes, partitions, formatting takes an extremely long time in Windows.

Is there a setting in UEFI to make the 2.5 SSD port operate normally in Windows? Or maybe an updated UEFI or driver? I'm using version ALDER109 UEFI.

Things I've tried:

• Many UEFI settings - Configure SATA as "Solid State Drive" and "Hard Disk Drive", ISATA, Unknown, etc. Disabled all other SATA ports. Changed CPU to Turbo Performance. Various other settings, none worked.
• Downloaded the official SEI12 Drivers and updated all drivers - in Device Manager, everything looks normal
• Changed system time in UEFI, Windows, and Linux (corrected Linux RTC to use local)
• CHKDSK /f - no errors
• SFC /scannow - errors corrected, no errors since, didn't help
• REPLACED THE DRIVE with TWO OTHER *BRAND NEW* Samsung drives (3 total, exactly the same issue)
• Put the drives in other PCs and external enclosures and they operate normally - very fast, no issues
• SMART test shows CRC errors on all 3 drives - only in Windows on the SEI12. In other PCs the drives do not generate CRC errors
• Probably some other things I'm forgetting (I've done a lot)
  

I see a lot of Drive Warnings in Windows Event Viewer with all three drives, but there are no errors with the disk when scanned. (see pictures)

This feels like a bad SATA cable but there are no cables, could be the port on the board. I'm still within my return period but I wanted to check if there was a UEFI setting that I'm missing before I return the device. Also, since I've tried multiple drives, I can't imagine my lottery luck would draw three bad drives, especially considering they operate normally in other PCs. So I have to believe it's a setting, driver, or bad port (or other component) within the PC.

Let me know if any additional information is needed.

Adding screenshots of benchmark and block scan in Linux. Write speed is less than half what it should be but it's at least usable. In Windows it hangs so bad for so long that it's not even worth using.


Any help or should I return this box?

Hello there,
Sorry for your trouble.
Pls contact our email.
We can send you a SATA cable to test.
Are you testing the read and write speed of large or small files?

Is there a setting in UEFI to make the 2.5 SSD port operate normally in Windows?
No,it can't be changed.

So I guess it was the port on the unit (as I suspected). I returned the original box and purchased another SEI12 1235U 16/500 and the Samsung 870 EVO SSD performs as it should (see pictures).


I'm also not seeing any disk errors in Event Viewer and drive diagnostics complete as expected without errors.

Now to go through the fun of setting up my dual boot and operating systems again :) (no worries, I enjoy it)

Thanks for a great little toy!
