Hello,


In december my girlfriend got me a external T9 samsung ssd for christmas.
It has been working normally untill the last month, it seemed to be really slow in running / copying things unto the drive so I did a test to see what the write / reading speeds where.
In stead of the 2GB+ speeds it should get, its only reading and writing around 35 MB / sec, I removed everything off the drive yesterday ( that took forever) and reformatted it today hoping that would fix the issue but sadly it hasnt.

I am running chkdsk /f /r /x atm but looks like thats gonna take all day and fear I might have jumped the gun on starting that but it seems unsafe to stop it now, even on a empty SSD?

What can I do at this stage?

ISTM that the drive is running at USB 2.0 speeds. Perhaps there is a problem with the USB 3 signalling pins?? Have you tried a different cable or USB port?

Can you show us a SMART report?

You could run the extended self-test in GSmartControl (Self-tests ->Test type -> Extended Self-test). This should run wholly within the drive, without any data transfer over SATA/PCIe or USB. It will test every block.

I tried different cable and other USB ports (all 3.0) that used to give the full speed in the past.
No changes.

I dont think I can test anything at the moment with chkdsk running, more then 2 hours in and only at 11% of stage 1...
When I look under devices it also no longer shows the 2 TB and a access denied when I try to double click the drive, i can only only assume that will be back to normal once chkdsk is done?
Or is there a way to safely stop chkdsk from running or is there no risk considering the drive is empty anyway, just dont wanna void warranty.

Weirdly enough it doesnt detect SMART for that drive in GSmartControl, nor can I enable it so I cannot do a self test there.

CHKDSK has completed the file system part of the test and is now reading every sector. It should be safe to kill it.

ok, thanks I cut it.

Contact Samsung for a possible RMA.
Thats what the warranty is for.

I will if needed, problem is my gf is from the states and im from Belgium so would have to ship it to her before she can send it back so was hoping there was a way to fix it instead of going through all that hassle.

Downloaded Magician, neat little software, updated firmware, did scan and self tests, 100% health and no errors but sadly the results stay the same.
Smart results all show up as good too (wanted to add the results but no idea how to add a file here)

The only thing it does say is that I should try to connect it to a differend USB port, tried every USB port on the PC and the message always remains the same (which it doesnt give with my other old external drive thats not a SSD) I'l try it at a different PC this weekend but I fear its clear by now that its just broken somehow.

Thanks for the help everyone.

Yeah, its biting a lot of people. They thought SSDs were singing, dancing and forever.

If you have another PC then plug in your SSD into that via USB. Do a checkdisk scan, and a crystaldiskinfo one as well. Might also be worth checking if there are firmware updates and if TRIM is enabled in SMART settings.

If the drive is "bad" then whip out the receipt and hope it's with warranty.

The Magician screenshot shows the results of a short scan. I would be more interested in the extended/long scan. This should test every sector on the drive without transferring any data over USB. If this test completes within 15 minutes (?), then that would point to the USB-PCIe bridge IC or the USB link as the source of the slowdown.

SSD <--> PCIe-USB bridge <--> USB host​

The bridge IC is an Asmedia ASM2362:

I started the long scan, 1h 15m in, gonna take 16h for full scan.

That suggests that the SSD itself is bad rather than the external components or USB connection. But that conclusion is only valid if the tests are not internal. :-??

I did check the NVMe spec and there is in fact an internal extended test, so I'm confused.

I'm starting to think that Samsung's software is rubbish. (I recently found a file system corruption bug in Samsung's Data Migration tool. This also uncovered a bug/deficiency in CHKDSK.)
