[SOLVED] Issue with copy speed in pendrive

[Akshae Samson]

Whenever I copy something to my pendrive, the speed goes to ~30MB/s then it comes down to 0KB/s. Then again accelerates to around ~30 MB/s then again decreases gradually to 0KB/s and so on. It is really weird to copy, lets say, 1GB with this fluctuation! Tried both Fat32 and NTFS but no luck.

Pendrive - SanDisk Ultra Fit
Capacity - 32GB

what the source?

Copying from PC to pendrive. It happens mostly with larger files, say 600MB or above.

Some transfer speed fluctuations is normal but not to this extent.
Does this problem also show up with other storage?


Assuming your PC's storage is alright, a possibility is a usb driver issue.
You can try to reinstall drivers by

Going to Device manager
Uninstalling the usb controller (Should be under Universal Serial Bus controllers)
Rebooting
Reinsert usb devices
Wait a while for them to install

Ps: You might lose mouse and keyboard functionality

Consolidated reply to all plus more info.

• updated drivers in the Device Manager and everything looks up-to-date
• copying from hdd (pc)
• this pendrive is Sandisk Ultra Fit 32GB 3.0 (putting it in 3.0 slot only)
• Noticed it happens in other computers/laptops too.

Q — is there something with the “allocation size” while formatting?

issue could be the hdd in the pc can't read fast enough
