Transfer is slow when using a 128GB USB3 thumb drive, yet works smoothly with a 64GB version.
Windows 10 64, latest version installed. ASUS Prime B550 motherboard with AMD 5600X. Front or rear USB ports are working, but my 128GB USB 3 drives are extremely sluggish—copying 11GB of video files takes a long time. I noticed the Lexar USB3 starts at 100MB/s, then drops to very low speeds, sometimes pauses completely for seconds before returning. I compared it to Kingston USB3 DataTraveler, which I thought was slower (around 7-8 MB/s), but it occasionally slowed down to just 1MB. My old Lexar USB3 64GB managed about 270MB/s, and after about ten seconds for an 11GB file it dropped to 100MB/s but still finished without issues. I've kept the drivers updated. Tried various formats like exFat and NTFS on both Lexar and Kingston drives. Recently heard some ASUS discussions suggesting newer or bigger sticks might work better, while older ones seem fine.
They seem fine, but it's possible the latest USB standards could affect the motherboard.
These drive speeds seem confusing. The specs show a 270MB/s read, but I'm seeing 150MB/s. Is this change normal? SSDs used to be faster, but newer models might lag. What’s causing the difference?
Back then Lexar was among the best... A few quality options remain, but you'll need to search carefully since they don't always match the marketing claims.
It seems like the situation has shifted a lot since you last used a drive. Many well-known brands are no longer available, and pricing has become unpredictable. The idea of using a thumb drive for things like USB3 is confusing—especially when speed matters. Overall, the current tech landscape feels chaotic. For faster performance, switching to a solid-state drive such as the WD_BLACK P40 Game Drive would be better. It’s larger, more affordable than some options, and offers decent speed.
