Have you tried using dd to test the speed? It doesn't even need a file
system as it writes directly to the device. I've done this in the past
and it tells if it is a file system issue or a hardware issue. One
thing here, it will destroy ANY and ALL data on it if you let it run
until it finishes. Make sure you have nothing you want to save on it
when doing this. I might add, I like this over rsync --progress because
it doesn't have a file system in the middle.
Commands I use to test this.
dd if=/dev/zero of=/dev/sd bs=4k conv=notrunc oflag=direct #disables cache
Don't forget to complete the disk device in the "of=" section and you
can leave off the comment as well when typing it in. You may also want
to adjust the other settings or leave out some to test things. See if
you can figure out a way to tweek it a bit. Sometimes you can add those
to the mount options to make it work better, so I've read anyway.
To monitor the speed, I found this years ago and it still worked a few
months ago when I was testing a stick that was giving me problems.
Turned out, the stick was dying a slow death. The dd test finished it,
with errors.
watch -n 10 kill -USR1 <pid of process>
I use Konsole here which has tabs but you may use something similar that
will work just as well. I start the dd command in one tab, then go to
other tab and find the process number for dd there with ps and grep. I
then use the above and replace "<pid of process>" with the number, leave
out the <> as well, just the number itself. When you go to the tab
where dd is running, it updates about every ten seconds with speed and
other info. I've found it normal to start out fast and then slow down
as it goes. Since it has no moving parts, no clue why it does that.
Someone else may see this and have a much better method but that has
worked for me in the past. As we know, some USB stick and other memory
type cards can get fussy or go bad.
Hope that helps or at least gives some ideas.
Dale
:-) :-)
P. S. I just copy what folks post, I don't claim to understand the
inner workings of this. LOL I do know, it destroys data tho. Always
be careful with dd and if and 0.

There are a number of things which might be going on here.
To start with, you can get the kernel, user, and wall clock run times for commands by prefixing it with "time". So:
time cp <large file> <USB mountpoint>
Will get you more precise answers with much less effort.
As for the performance of the USB drive in question, there are a few things that might be tripping it up.
Firstly, writing flash memory is significantly slower than reading it. Some drives deal with this by having some kind of internal cache mechanism. Many deal with it by using a pile of smaller chips instead of one big one and striping the writes. If the Phillips drive just used a few large chips instead, then it's just slow to write to and there isn't much you can do about it. I've seen a lot of cheaper drives that are that way.
Double check that the alignment and block size are correct for the drive's internal structure. That can cause some pretty massive performance hits if it's incorrect.
You can also check the output of the dmesg command for any errors the system is encountering with regard to the drive.
I don't know of any reason to stay away from usb 3.0 on Linux, but if you have USB 3 devices on both ends and try to hook them together with a USB 2.0 or 1.1 rated cable that could easily cause some problems... I assume you're plugging the drive straight into the machine's socket. If you're using the front panel though try one of the ones on the back. There may be something up with the case wiring.
I've never had a Phillips USB stick, so maybe do some tests with another brand of stick and see if it has the same problem. Kingston or SanDisk or something. One of the ones where memory is their primary focus.
You could definitely check performance on a different OS. There may be driver-related performance issues on this model of drive or even this specific drive.
Instead of NTFS you could also try UDF. It's supported on both Linux and Windows Vista and newer. (And even XP I think, but only an older revision of the filesystem.) Being an open standard it is quite a bit more stable on Linux than NTFS, doesn't need a userspace driver, and still supports larger drives and files. You can find Linux and Windows formatting instructions on the web pretty easily. Big thing is that on Windows it's available via the format command, but not in the GUI.
That's all I can think of at the moment. Hope it helps.

OK, unless you made a typo and the "minutes" were meant to say seconds, this
is ridiculously slow.
You could run some tests to see what is causing the delay. The veracrypt
algos & cipher iterations, the fuse based ntfs-3g, or the USB stick's
controller.
However if, as I understand it, all other variables are the same and the only
change was to replace your Verbatim 64G USB 2.0 sticks with Philips 128G USB
3.0 sticks, then the slow writes point to the Philips devices being the
culprit.
Some years ago I tested some USB 2.0 sticks of various sizes, from 256M up to
32G and recall the smaller the USB stick the faster the write performance, so
differences in writing speed are normal. The writing speed you're describing
however is a clear indication of something being wrong.

Without knowing the internals, a brand may offer only an unwarranted
assumption of performance. We saw Western Digital disks being sold as CMR,
while having SMR internals. A brand could switch OEM suppliers, or
components, making benchmarking unreliable.

USB 3.0 is faster and USB 3.2 when available will be even faster. So use
whatever the USB ports on your PC offer.

In-kernel fs drivers are measurably faster than fuse based fs for well
understood reasons. However, if needs must and the fs you require is not
available on Linux, then some compromise will be required.

You may want to run some tests on the sticks you have, if only to bottom out
what their performance is on different PCs and USB ports:
dd if=/dev/zero of=/run/media/<USER>/<STICK_LABEL>/TESTFILE bs=512
count=600000 oflag=direct conv=notrunc,fsync status=progress
Use a large enough file to make sure the USB controller cache gets saturated.
You could use a ramdisk/tmpfs as an input file.
If you write directly to the device as Dale suggested it will wipe data, so
keep a backup of anything you need first.
You can experiment with different filesystems and in the first opportunity
with a different make of USB 3.0 stick. You'd soon be able to determine how
good the real world performance can get and if the Philips or something else
is causing the problem you've experienced.
A note about UDF: it works and it is versatile - but ensuring
interoperability between different OSs can be tricky. Check some suggestions
here:
https://askubuntu.com/questions/27936/can-and-should-udf-be-used-as-a-hard-drive-format
and here:
https://superuser.com/questions/39942/using-udf-on-a-usb-flash-drive
Ultimately such tests are an attempt to eliminate methodically all other
factors, until you isolate the cause of the problem you are experiencing.

I checked the man page, I see nothing about the show progress option.
You can bet I'll try that next time tho. I saw a video of someone else
using it and it is a lot easier than having to switch Konsoles and type
in more commands.
Thanks for sharing that option, that isn't in the freaking manual I
might add. This is one time where telling someone to read the manual
wouldn't work. ROFL
Awesome!!

Are you sure?
This is what I see here on line 47:
"status=LEVEL
The LEVEL of information to print to stderr; 'none' suppresses
everything but error messages, 'noxfer' suppresses the final transfer
statistics, 'progress' shows periodic transfer statistics"
I find this useful in seeing the transfer speed drop in real time as the cache
gets saturated.

Ahhh, I didn't see the status part. It's sort of hiding in a
subsection. At least I know now that the version I have installed has
this option.
I wish I could view man pages like I used to in Konqueror. It displays
like a webpage and is much easier to search through.
Thanks for pointing that out.

Yes, I also liked the old Konqueror interface. Searching for keywords e.g.
"progress" within man pages works if you preface the keyword with "/":
/progress
will find it and "n" or "Shift+n" will jump forward and backward to any other
instances in the man page.

That doesn't work here. I can type in /progress but it just shows up at
the bottom. If I try "n" or shift+n I just get a n or N. Maybe my man
page uses something different.
That said, I haven't tried Konqueror in a while so I found it, it gives
a error but I can type in man:dd and it shows up. It has a search
tool. Last time I tried it, wouldn't even come up. That was a while
ago tho. Guess it got fixed.

Yes, it shows at the bottom until you hit enter to execute the search. Then
it highlights the next instance of the searched string. Just like Vim/Vi
does. Hmm ... I wonder if I have set up some special environment parameter on
my systems and forgotten about it. :-/

*cough cough* I didn't hit enter. Just did and it worked. Now to get

It's a feature of whichever pager you use, rather than man itself. Less
does it, as does most, but others may differ.

I miss that too. I use mankier.com these days, which gives similar
benefits. I have a shortcut set up in chromium so typing "man dd" opens
the page in mankier.com.

Many years ago, there was an X11 man page and gnu info viewer that I
used to use, but I can't remember the name of it. This was probably
20+ years ago (pre GTK and Qt), so the chances that it's still around
are small...

Perhaps x11-apps/xman? I remember it as you do, but have not used it
in years, so I'm not sure if this is it or not. The info command also
seems to have access to man pages, but it doesn't seem the most obvious
way to get there.

I do remember using xman closer to 30 years ago, but what I was
thinking of was something a bit newer and fancier than that -- I
recall it also being able to navigate info pages. Or I may be
conflating two different apps: one for man and one for info.
It may have been tkinfo or tkman

I just directly formatted one of my two Philips 128G USB 3.0 sticks with
"mkntfs" and the write performance without VeraCrypt did not improve.
Further searching the web I found that vendors were rarely specifying
the writing speeds of their USB sticks at all, and if they did, there
was a tendency to exaggerate. See for instance
https://www.lifewire.com/sandisk-extreme-pro-solid-state-flash-drive-review-4689258
Checking what SanDisk USB sticks I could easily obtain locally I finally
picked two SanDisk Ultra 128 GB USB 3.0 sticks, and it turned out the
writing speed was just amazing, with and without VeraCrypt. So basical-
ly, USB 3.0 denotes a standard rather than a (write) speed, and it pays
to search the web for benchmark tests before buying.
Thanks for all the help and support the participants on this list are
providing ... :-)
Sincerely,
Rainer

Could this be the 512B / 4K sector size problem?
If performance is horrible, it could well be a stick / partition
mismatch. I never investigated, but if the stick is faking a 512B sector
size, so the partition is using 4K blocks aligned on sector 1, it will
kill write speed, and in time will kill the stick, too!
Cheers,
Wol
