    I FOUND THE FIX, only took me a month.
  

*by B***N on Reviewed in the United Kingdom on August 15, 2021*

So, to fix this, apparently, this problem only occurs in some machines (in some windows builds I am guessing), you need to download JetFlash Online Recovery, press download, and select the "Jeflash Series" version. Open up the software, and plug in any 900 series (I know that it at least works on 920 and 930C models) Transcend USB drive. Follow on-screen instructions to perform the recovery, after the first run, you need to perform the recovery again (don't know why, so don't ask me). Then, it would act just like any USB and you can do whatever you like to it. Happy days!It took a lot of time to work this out, especially without the help of Transcend technical support since they did not respond, so please leave a like so I know I helped someone!The specifications of this driveWrite12GB (or at least 10GB) of accelerated 400MB/s write (It could be DRAM but I think it is just SLC write caching)Consistent 80MB/s write when the 10GB cache runs out20MB/s random writeReadConsistent 400MB/s (advertised as 420MB/s) throughout20MB/s random readCapacityTranscend always skimps out a bit, it has 123,700,000,000 bytes, not the 128GB promised.GOD, if it was like that out of the box, I would have given, 5 stars. Sadly though, Transcend technical support did not even reply to my requests...Build quality is good, and small, considering it is basically an SSD wrapped in a tiny USB form factor.

Ich habe den USB-Stick (JetFlash 920 128GB) der Firma Transcend einen ausführlichen Test unterzogen:Laut Hersteller soll der USB-Stick eine Lesegeschwindigkeit von 420 MB/s und eine Schreibgeschwindigkeit von 400 MB/s haben.Laut meinem Test mit AS SSD Benchmark und anderen Tools (siehe Screenshots) kommt man auf folgende gemessene Werte:Seq-Lesen: 224 MB/sSeq-Schreiben: 331 MB/s4K-Lesen: 15.4 MB/s4K-Schreiben: 22.63 MB/s4K-64Thrd-Lesen: 23.1 MB/s4K-64Thrd-Schreiben: 31.33 MB/sZugriffszeit-Lesen: 0.14 msZugriffszeit-Schreiben: 0.36 msDer AS SSD-Score liegt bei 191 Punkten.Eigenartig ist, dass der Stick beim Schreiben schneller ist als beim Lesen.Bis er von Windows (nach dem Einstecken) erkannt wird vergehen übrigens jedes Mal ca. 25 Sekunden. Das ist nicht akzeptabel.

    Only fast with part storage
  

*by S***K on Reviewed in the United Kingdom on August 3, 2021*

First 10 GB on the drive will be fast around 330 MB/s write. Once you get to about 15 GB usage it will drop to 95 MB/s write.The drive is 115 GiB (123,712,831,488 bytes) so, so not 128 GB, but 123.7 GB. This causes it to have less space than true 128 GB (119 GiB) drives.It does allow you to use the full space at 95 MB/s, but nowhere near the indicated/advertised speeds over the full drive.Update:It looks as if it uses some form of fast cache memory. When unplugged and used again at a later date it will be fast again, so it depends on how much data you need to copy at one time. Because of this you'll see it get high marks in the test and benchmarks people run.
