Recently i did purchase thumb drive which is verbatim 64GB pinstripe (sku: 49318) and instantly i decided to give it some basic test like copying files onto it and i noticed very weird behavior, at least something i've never seen with any other usb drives before: transfer speeds on copying files to the drive fluctuate all the time between two exact values, 18 and 26MB/s. Write graph looks sinusoidal as you can see on attached screenshot.
I do not expect it to be the fastest drive in the world as i am aware what i did purchase which is one of the cheapest but ok 64GB usb 3.0 drives. I'm just wondering what may be causing such oddities with write speeds/write process. I'm curious with what ideas you can come up.
Also i did attach to this post screenshots from crystaldisk done on this drive and other older usb3.0 drive from company named "Goodram" and my ancient usb 2.0 ocz rally 2 drive, just for comparison. All these were done with these drives connected to exactly the same port and this port is 100% sure usb 3.0, one after another, all drives formatted to exfat (filesystem doesn't matter much anyway). I do not see any firmware updates on verbatim's website. By the way i'm under impression this goodram drive behaves like usb2.0 drive, not 3.0, despite having blue color port, correct me if i am wrong on that.
Later i'm definitely going to check the drive after full format and under linux as well to see if these fluctuations are operating system independent.
