[Bug 1242085] Re: Low write speed to USB disks - do something!
Darek, as per http://www.asus.com/Motherboards/P5WD2_Premium/#support an update is available for your BIOS (0709). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.
For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.
Thank you for your understanding.

- Problem description:
- I noticed very very low write speed to USB disks, especially to the new ones with USB 3.0. The "Disks" tool shows write speed about 7 MB/s !!! After start benchmark this tool shows write speed about 17 MB/s but imidiatelly goes below 10 MB/s. Same low speed during copy e.g. 3GB file manually to USB 3.0 disk. There is no such problem with read or access speed, only write. Unbelievable !!!

Even the write speed on my laptop is more important to me.
What I found about this bug (VERY IMPORTANT NOTE):
- In old realese 12.04 LTS disks works OK.
- In 13.04 disks works faster than it is now in 13.10.
- - If disk is formatted as NTFS the write speed is the lowest.
- - If disk is formatted as EXT4 the speed is x2 better.
+ - If disk is formatted as NTFS the write speed is the lowest.
+ - If disk is formatted as EXT4 the speed is x2 better.
- If disk is formatted as FAT32 is low too.
- - No matter if disk is connected via USB 2.0 or USB 3.0. The low write speed is always the same.

- - There is no such problem with read or access speed. Write only.
