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?

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,

As several people have mentioned, you can only write to a USB stick
"n" times. As the drive gets used more and more, writes will get slower
and slower as the drive has to find "fresh" locations to write to. USB
sticks are NOT rotating magnetic media or even SSD, so you really can't
expect similar speeds. Don't think of USB sticks as hard drives, more
like CD-RWL (CD, read-write limited).
There are a number of motherboards out there where the firmware can
force a USB3 port (normally using the xhci mechanism) to use the slower
ehci mechanism, thereby negating the USB3 speed. You might check your
BIOS/UEFI settings to see if that's the case.
Also verify that the USB stick you're futzing with is, indeed, USB3
compliant and that all OTHER devices using that port are USB3. The port
will slow down to accommodate the slowest device on it.

Hi Ed,
What was the file system of your target usb flash drive?
Ext4? NTFS?

I can reformat if need be.
Thanks for the feedback!
No problem, used NTFS too. And I have several sticks I
can reformat to ext4 and retest.
I am suspicious of qemu-kvm being the culprit.

Hi,
I use usb 3 sticks since years for running Fedora - OS on the sticks (32GB). By the time,
may be in about 1 year the USB stick becomes slow and slower, because it's not made
for OS's, it's more and more damaged, then I use the sticks for films and fotos,
where slow is no problem. On Fedora there is F3 to test. On Windows there is a program, I
think it's called Crystal Disk Mark or Crystal Diskinfo - I don't remember, which
of those - , where You can check the write and read speed of the stick.
Kind regards

My kernel is 4.18.16-200.fc28.x86_64
I just copied a 3GB iso to a FAT32 partition:
real 2m6.738s
Copying to EXT4 and syncing took almost 3 mins.
So I don't see this problem with my laptop.
Check the mount options, maybe there is something like sync set,
although it still shouldn't take that long.
Try running "iostat 5" while it's copying to see how much I/O is happening.

Hi Sam,
Wow! You sure called that one! Thank you!
I ran to an fat32 and got:
# time cp Fedora-Xfce-Live-x86_64-29-20181029.1.iso
/run/media/tony/FAT32TEST/.
real 2m0.151s
user 0m0.005s
sys 0m1.483s
This is the ntfs stick mounted from the desktop:
/dev/sdc1 /run/media/todd/xxxx fuseblk
rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096
0 0
It was fast.
This is the way I originally mounted it:
/dev/sdc1 /mnt/xxxxx fuseblk
rw,sync,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096
0 0
And I do see the "sync".
This is the code where I mounted it:
mount -o users,exec,sync $Device $Target > /dev/nul 2>&1;
With "sync" removed, this to a 3.1 port to the Samsung in question:
# time cp Fedora-Xfce-Live-x86_64-29-20181029.1.iso /mnt/Rent-A-Nerd/.
cp: overwrite
'/mnt/Rent-A-Nerd/./Fedora-Xfce-Live-x86_64-29-20181029.1.iso'? y
real 0m8.254s
user 0m0.014s
sys 0m1.318s
And to double check, unmounted and mounted it somewhere else:
# sha256sum Fedora-Xfce-Live-x86_64-29-20181029.1.iso
/run/media/todd/RENT-A-NERD/Fedora-Xfce-Live-x86_64-29-20181029.1.iso
