Hi All,

FC28, x86
Xfce 4.12

I am trying to copy he new Xfce Live ISO (1.4 GB) over
to a Samsung usb 3.1 stick.  It is taking FOREVER.  And
this is typical.

Is your usb also slow by any chance?

Extra info.  "dd" goes like the wind.

I just reported it:

usb is excruciatingly slow:

Dear Fedora,

Would you guys please fix this for me.  It is driving me insane!!!

Fedora 28, x64
Xfce 4.12
motherboard: Supermicro X11SAE-M

USB transfer speeds are excruciatingly SLOW.

This is a Samsung USB-C flash drive in a USB 3.0 slot

$ ls -alh Fedora-Xfce-Live-x86_64-29-20181029.1.iso
-rw-r--r--. 1 qemu qemu 1.5G Oct 30 14:56 Fedora-Xfce-Live-x86_64-29-20181029.1.iso


$ time cp Fedora-Xfce-Live-x86_64-29-20181029.1.iso /mnt/Rent-A-Nerd/eraseme.iso

real	49m21.251s
user	0m0.111s
sys	0m16.157s


49 Minutes for 1.5 GB !!!!


Also, please not that "dd" is fast as the wind! This is the same file dd'ed to a Kanguru Flash Blue 3 to the same slot:

# time dd bs=4096 if=Fedora-Xfce-Live-x86_64-29-20181029.1.iso of=/dev/sdb
370432+0 records in
370432+0 records out
1517289472 bytes (1.5 GB, 1.4 GiB) copied, 143.756 s, 10.6 MB/s

real	2m23.760s
user	0m0.126s
sys	0m1.822s

Two minutes.  Yippee!

So it is NOT the hardware.

This problem repeats on all my different flash drives, including SSD flash drives in USB 3 carriers.

Many thanks,
-T
