Been a bit busy with the new Mac. Finally found some time to post this. Tests were done on a Mac Mini M1 16/256. The Mac Mini has 2 Thunderbolt 3 USBC ports.


My 2TB Adata SX8200 Pro has the SM2262ENG, the newer but lower clocked controller.


SX8200 Pro in an Acasis Thunderbolt 3 40Gbps external enclosure. It has an Intel JHL6340 Thunderbolt 3 Controller. I thought it would be faster than this. Will test it in a PC when I get the chance.


For comparison, the speed of the onboard SSD in the Mac Mini M1.

Overall, I'm happy with it. For normal use, there's no discernible difference between the internal and external SSDs

Maybe the SSD incompatible with Thunderbolt 3 Controller. Looks like only running 20Gbps speed, or only 2 lanes of PCIE.

I think you're right on the dot. Mac reports "Current Link Width: 0x2" Looks like only 2 lanes being used. I have another enclosure coming in with the JHL7440 controller. Will test that one later. The enclosure I tested with is a JHL6340. Might also borrow a different brand of SSD, maybe something with a Phison or Samsung controller, to test out.

Do you use any external Thunderbolt SSDs?

I don't have external Thunderbolt SSD.
You need it to run full 40Gbps?

is this chip controller "Silicon Motion SM2262ENG" on my 2TB adata sx8200 pro still a good chip, coz i just purchase this nvme ssd last 2 week only.

See post #121, soonwai have same model with same controller and he done speed test with it.

Unless you're transferring hundreds of GB constantly, you won't feel any difference in daily use.

okay, understand

Should be ok I guess, the original one is definitely faster. I can't really tell since I only have one and it's external. It's still plenty fast and at RM900 for 2TB, cheap.

Read this, apparently there're now 3 different versions of the SX8200 Pro.

thx for the info bro, i brought it at rm950

Unfortunately I have XPG SX8200 and recently running into random BSOD with the error code:

WHEA_UNCORRECTABLE_ERROR

After reboot, the NVME drive undetected until I power cycle my PC.

And the BSOD constantly happened when I run chkdks /r and in the middle of the scan.

Is my NVME drive dead or Windows just being Windows?

What CPU you running? Do you OC the RAM?
Check on CrystalDiskInfo or HWiNFO how's the drive health is.

Oh wow, how old is the SX8200?

Ryzen 2200g
B450 Fatal1ty ITX bios v4.40
T-Force DELTA RGB DDR4 3200 MHz (Standard XMP @ 1.35V)
Sapphire Nitro+ RX580 with latest driver
XPG SX8200 Pro 512 GB





Completely assembled my PC since February 2020

Strange this is I can use no problem, even under stress mostly from gaming.
The BSOD is easily reproducible when running "chkdsk /r" and "CrystalDiskMark"

Your SSD still looks good.

Are you still using Win 10 version 20H2?
Have applied update?
There's a bug with that version that will caused windows files to be corrupted and damage windows partition if run chkdsk on SSD.

If already update it, in theory you may be able to repair the damage by running chkdsk in offline mode. And don't use chkdsk on SSD anymore, SSD don't need it.

Also do RAM testing using Testmem5 to make sure it's not because of the OC RAM.

Yes, 20H2 with the latest update.
What do you meant by chkdsk in offline mode?

So the solution is to format Windows 10 and reinstall old version?

And yeah it's true, I never face any BSOD prior to 20H2 (except when I was trying testing undervolting my GPU, but then the error code is different and kernel dump was made. But this one no time dumping to be written as the SSD somehow like disconnected from MB).

If you got run chkdsk when using 20H2 without the patch, it might have caused the file corruption.

Maybe offline chkdsk can fix it. Offline mode means check the drive when it is not running Win 10. Run CMD as Administrator, then type "CHKDSK C: /F", it will ask to schedule chkdsk when the PC restart. If still encounter BSOD then can try partition back the drive, format and reinstalling Win 10.

This is assuming the BSOD is because of file corruption. If because of other issue then have check some more.

Cant trust those SSD health check punya , I had 10pc running same model NVME m2 , 8 out of 10 rosak less thn a year , 1 canot detect , few unit run windows random bsod , check health all ok then format some stuck on windows 10 installation , sometime thy will finish installation till random bsod in windows again . The chipset controller of NVME is the culprit . i replace all with normal 2.5" SSD settle , no more BSOD . It is every hard to find out what wrong if u only hv 1 pc , i hv 10 same spec pc thats y i can 100% confirm that stupid NVME problem .

I am wonder how you get such high speeds with the Adata, or I am missing something.

I have the 2 TB version and using ORICO Thunderbolt 3 (SCM2T3-G40 model), and I am getting write speeds of max 800MBps and read speeds of 1600 MBps. Is it cause the enclosure comes with passive thunderbolt 3 cables instead of active?

Not sure why yours would be slower. Though I use a different Acasis branded enclosure, it has the same Intel JHL6340 controller as your Orico. I'm also using the short passive TBT3 cables that came with the enclosure.

What computer are you using?
