  • Linux Lite: 3.8 64bit

  • CPU: Intel i5-3340M

  • MEMORY: 8Gb

  • VIDEO CARD: Intel HD Graphics 4000

  • Kernel: 5.x
Hi all. I'm transferring files from my Dell E6330 Laptop to my USB drive. In windows I get anywhere from 120-130mbs constant. Now this is transferring to a 7,200 RPM drive. I do have an SSD which sometimes is a bit faster transferring files. Now the problem is, on my laptop the transfer rate goes below 30mbs for the same files I transfer to my Windows PC. The laptop has USB 3.0 ports and I'm using a Corsair 360GB SSD so my transfer rate should at least be near 100mbs. Is there anything with Linux Lite I can do to speed up the transfer?


Thanks

What file format is on both the source and the destination? It also depends on the file type/s that you are transferring.

Hello, I'm transferring a 64GB video .mkv file. I took a pic of my speed right now.  https://ibb.co/dEczqG
File format you mean? My USB stick? It's exfat and the SSD is ext4 format.

Thanks

It could be that the USB3 driver is not working and defaults back to USB2/USB.
I do not have any LL machine with USB3 to check but, just an idea.
And just in case... install all Linux Lite Updates and check if drivers are available.

Cheers!

Thanks I will do that. Also, when it first transfers it starts at over 100mb/s and then it drops.

Tried the updates speed stays the same. Hmm, would there be any other 3rd party drivers for USB 3.0?

Insert the USB. Open a terminal:

Code: [Select]
df -h
get the drive letter of your USB. Then do:

Code: [Select]
sudo hdparm -tT /dev/sxx
where sxx is your USB. Report back the results.

Thank you this is what I come up with.: https://ibb.co/kKpokG
Where it says PATRIOT that is my 256GB USB.
The speed seems right but I don't understand why it drops off so low while it's transferring.

Speed is fine. I don't think you can get sustained speeds with a file that size.

Thank you, I will do some more test with smaller files and see how it works.

Thanks again.

You could also make your USB ext4 file system. Then test ext4 to ext4 under USB 3.0

Hello, actually I didn't think of that I will surely test out the ext4 file system on my USB and see how fast the speeds are thank you.
Reason I use exfat is because I transfer files from my Linux PC to my Win 7 PC :D  I just came across a program that lets you read the ext file systems in Windows, it's called Ext2Read, so if the speeds do improve I will use this program to transfer my files instead of exfat.

Couple of suggestions I would add to this. The fastest way to transfer huge files from a Linux box to a Windows 7 box is to use grsync via ethernet. Also .mkv files are a kind of universal container file which can contain differing OS information and meta-data depending how edits are made and simple things like Windows fonts can slow down or mess up transfers between Linux and Windows. Add grsync to Windows 7, and a commander style file manager, and then ethernet the Windows box to the Linux box.

If you are going to continue using USBs between the transfers format to ext2, and install ext2fsd to Windows 7 and a commander style file manager. Still 64G is an awfully big container file for a run of the mill consumer style (Windows 7) box to copy from Linux no matter how you do it and meta-data changes and editing quirks can mess with transfers.

*Important* I believe ext2fsd will work fine in Windows 7 64bit mode as long as the USB being accessed is formatted to ext2. There are issues with 64bit mode in newer Linux OSs on ext4 file transfers.

Thanks for the input. Hmmm, I think I will try your suggestion to trinidad. First I'll try ext4 and see if there are any issues. If there are issues I will use ext2 file system and see how that works. I think I will just try that method, being I don't want to run Ethernet cable right now :D. If speeds do improve then I will leave whatever file system gives me the best results.

Tried ext4 , ext2, then tried to transfer a smaller 5GB file all the same speeds, average 17.5mb/s. I was thinking if I install Wine and download the USB 3.0 drivers from Dell would that work? Would it install correctly? A shame Dell has no Linux support on their site for my model of Laptop.
