On any other filesystems I have used, using sync makes performance suck.
No idea about what is normal/ok for btrfs.
You might see if all btrfs filesystems are using sync or just the
removable ones are.

So it is only slow on the slow port? If so it kind of sounds like the

smartctl --xall sometimes works against usb disk and
sometimes it does not work. if it works it will tell you the write
cache status. The sync and/or btrfs fil
The drive is about 76% full but I don't think it's fragmentation since the
transfer of the same ~2 GB file to the portable drive is consistently
relatively fast from a blue or yellow USB port, and very slow from a black USB
port. Here's the output of "df -T /dev/sdb1" with the drive plugged in:
You might install usbview and run it. It will give you a gui window
and let you drill down and examine what each USB device looks like.
It would make me think it is some BTRFS issue. maybe for some reason
the disk is fragmented and having to write blocks all over the place.

The portable drive is a HDD, formatted with BTRFS (same as each of the three
F40 machines, the two desktops and the laptop). The desktops have HDDs and the
laptop has an SSD but they always have and the transfer speed used to be
faster, none of that hardware has changed. After noticing the slow
Is this a spinning disk or an SSD? And what are you writing to the
disk?And what filesystem is on the disk?

Testing a little more, the transfer speed between the desktop's black USB ports
and the portable drive is only slow (around 2 MB/s) in one direction, from the
desktop to the portable drive. From the portable drive to the desktop, it's
about the same as before, around 25 MB/s. With the laptop's 3

Once you've verified it boots into new kernels, feel free to delete the

I have a USB 3.0 portable drive which I've used for years with two desktops,
each with black USB 2.0 ports. I used to get roughly 25 MB/s transfer speed
which AIUI is roughly to be expected given that it's limited to USB 2. Lately,
the transfer speed is much slower, around 2 MB/s. I thought mayb
