OK for the low price, no turbo
For the rather low price, no turbo is to be expected. Read goes sequentially with approx. 160MB/s, write approx. 50MB/s. It gets slow with random read and write 10MB/s and 0.8-1.8 MB/s.
For comparison, a 3.5 year old USB-3 stick with 64GB and also from Sandisk has a sequential read rate of approx. 100MB/s and a write rate of approx. 36MB/s. With the random, it is sequentially 8 MB/s read and 0.7 MB/s write.
If you want speed, you have to invest more. This is enough for me, as I was looking for USB-C and -3 in one stick. Write ISO on the notebook with USB-C and then mount it in the server with USB-2 or -3 and all that in one stick.
By the way, the stick is formatted with FAT32, so no large ISOs fit on it. So reformat with NTFS if possible.Pro
- USB-C and 3 in one housing

Writing speed very slow
When I write/read a folder with approx. 15GB (photo/movie/docs...) with my Lenove NB resp MacBook Air the speed differences are too big!
read from the SanDisk, then it takes approx. 2min05 = very good
write from the laptop or MacBook Air to the stick 16min02 resp. 25min28, then I can enjoy more than a coffee. Actually, I expect similar speeds in both directions.
But yes, at this price you shouldn't complain.
Pro
- Reading Speed

Unfortunately, the stick only has 32 GB instead of 128 GB
The manufacturer must have made a packaging error
The 128 GB packaging contained a 32 GB stickThis review was created for a different variant: Ultra Dual Drive Go (128 GB, USB-A, USB-C)
Plastic housing
The plastic is thin and unstable. If you think you can carry it around with you, you'll quickly realize that it can't take much punishment. If you always keep your stick in a drawer, then you are probably very happy with it. If you take it with you and need it on the road, it won't serve you for long.
Pro
- Price
- USB-A and USB-C
Contra
- Plastic case can't take much
