About transferring files onto a usb

[Pinkly Smooth]

Hello to everybody. So I own an iMac from the years 2017. Just earlier, I transferred a file of 163 megabytes from a folder in my iMac onto a usb. It took several minutes to do this; about 3 or 4 minutes.
What I don't understand is that after when I put my usb in my MacBook Pro, which isn't as advanced and strong as my iMac is, I transferred the file from the usb onto the Mac book pro, and it took seconds to do so. I don't understand this. Is something wrong with my iMac, is it slow when it shouldn't be? I did a scan on Malwarebytes and it turned out clean. Pls advise. Many thanks.

Test the USB drive on every computer you have, both reading and writing. What are the results?

Hi I did the same thing on my MacBook Pro and it said it would also take 3-4 minutes, like my iMac, I cancelled the transfer because I saw how long it would take.
Is something wrong with my iMac though? Is this normal, that it would take this long?
Also, is there a way to test the strength of the iMac? many thanks.

It sounds like the USB drive may be the culprit. Reading speed is typically faster than writing speed, sometimes significantly so.
