Very slow data transfer to USB memory stick

(1/2) > >>

Ean:
Many thanks. I'm not a Linux lite worshipper (yet?), but on the whole I'm very impressed.  Ean.

I boot OSes on Sandisk Ultra / Extreme that have about 150MB / 100MB RW. Kingston call these HyperX. They cost more of course.
USB keys lying around cash registers in store are usually appaling regarding speed, specially write. But... these are not expensive. ;)

I use the "slow" one for archiving or low usage programs.
With Ultra, etc. using live OSes can be faster than standard magnetic hard drives.

Good luck on your quest Sir Knight! ;)

Ean:
Thank you for your reply.

The problem does not arise on Windows. I've just installed LL5.6 on another PC, and the problem persists.

Regarding memory sticks, I've long had a suspicion that quality control is bad even amongst makes such as Kingston, Toshiba (renamed Kioxia for some reason), etc.

I tested my memory sticks a week or so ago on a USB 2.0 port, using Crystaldisk 8. I only tested a few items so the thoughts I offer have little statistical significance. The 5 USB 2.0 sticks tested averaged roughly 28Mb/s R, 5Mb/s W. The 3 USB 3.0 (3.2 gen1) sticks averaged roughly 25Mb/s R and 10Mb/s W. What cracked me up is that two used hard drives I bought produced an average of 33Mb/s R and 25Mb/s W. This suggests to me that on write, it's the slowness of the memory sticks (even the USB 3.0 sticks) that is the limitation and not the speed of the USB 2 port. If so, this shows memory sticks up in a very poor light.

You're right about bad USB 3.0 sticks!

Ean.

Best wishes, Ean.

Hi,

I also have this on different slow network connections and Windows too.
Not sure if this is because the file is "cached" in memory and working on the file integrity verification or the progress meter having a delay.
I would vote for the first.
File system does not seems to be culprit.
Also would add that the write speed of the USB key can be really slow.
Try and benchmark the usb drive to see read/write speed.

Bonus: Even USB 3 keys can have crappy read/write speed.

Ean:
Didn't realise using capitals was a breach of protocol and won't do it again. It's just that I normally use capitals (when I don't forget) for main headings and filenames as I find them easier to see.

Ean.
