SDCZ74-128G-G46 This part number product which I purchased, on the box it says it can reach only 150mb/s, website said 400mb/s.
SDCZ74-128G-GAM46 part number on the other hand is the one who can really reach 400mb/s.
The ultra luxe usb 3.2 gen 1 sticks , even though they come in two indistinguishable model versions, they are priced differently.
Sandisk you have to inform people in a clear manner what you are selling and not to confuse them. Please inform why my SDCZ74-128G-G46 reaches only 150mb/s as per the box it came with, though when connected to pc is is named usb 3.2 gen 1 and it was advertised on the website as reaching 400mb/s. Please clarify what you are trying to achieve by the confusion caused.
Response from SanDiskBy SM OLS, April 3, 2026
We're sorry to hear about your experience. The SDCZ74-128G model supports read speeds up to 150MB/s for 16GB-32GB up to 300MB/s for 64GB variant and up to 400MB/s for 128GB - 1TB variant. However, speeds may also vary depending on the host device performance and usage conditions. Also, please be informed that, the suffix differences in model numbers are purely cosmetic indicators and do not change the core technical specifications of the drive.

Verified Purchase:Yes
Great storage capability, but drive gets excessively hot during operation
No, I would not recommend this to a friend.
