USB 3.0 Low Speeds Problem

johnpyla · 14 Mar 2015

Hi guys ,
i ve opened this thread to inform you about a problem that i have saw with my usb 3.0 ports.... As you know i have installed my drivers for my usb 3.0 ports but for a reason that i don't know when i ve put an External HDD 3.0 in USB 3 ports works great and i have great transfer speeds 65 mb/s - 70 mb/s when i transfer files with big size .... But when i ve put a usb stick 3.0 (flash drive) as Sandisk Ultra 3.0 16GB or EMTEC usb 3.0 16GB OR Transcend usb 3.0 32 gb (I have 3 usb flash drivers) i have very low speeds with maximum speed 11 Mb/s when i transfer a file with big size ...... What you believe happened ? Can i try something to fix this ? Please help me ...
Thanks about your responses !!
John !

What USB 3.0 ports? Back panel or front? Please also fill in your system specs by following the link in my signature, we need as much information as possible to even try to resolve problems, we can't just guess.

They are back panel ports .... I have not front panel USB 3.0 ports .... I ve made this with my system infos ..... Thank you about your interest to fix my problem :) As i know this ports are ASMEDIA usb 3.0 ports :)

Can you post which driver version you have installed for the ASMedia controller.

For what it's worth I get the exact same performance with my USB peripherals, my 1TB Touro Mobile gives fantastic speeds of around 100Mb/s where all my USB sticks (6 x Kingston Data Travellers) probably max out at around 10Mb/s. It could just be normal and nothing to worry about.

As i ve saw in my controll panel i have version 1.12.5.0 (ASMedia ASM104x USB 3.0 Host Controller Driver) .... Do you believe that these speeds are normal ? I ve believed that some months ago i had better speeds but ok .... Thanks for your responses friend :) If you believe that it's ok i ll mark it as solved

V1.6.3.0 is available for your motherboard, I've linked it below if you want to give it a go.

Check out this utility. It will give you lots of information on your USB ports.
I would look for the port you are plugged into and it will list the Speed that is being used.
I have read some reviews in the past and USB sticks seem to run very slow.

Keep in mind that USB flash drives wear out quickly. While they have controllers similar to a SSD, they are not as sophisticated and using a USB flash drive as a disk with repeated writes and deletes will slow the flash down considerably. When a cell is marked deleted, it's not cleared. It isn't cleared until the cell is needed again for a write. This takes extra time because the cell is cleared (write) before the new data is written so used cells take two writes. There is a very limited number of write cycles available for the memory cells so flash drives wear out to the point of failure.

Don't use flash drives like you would a real disk. They weren't designed for repeated deletes. Think of them as similar to CDs--Write Once and read from them. As with SSDs, data will always try to write to unused cells first. If there aren't any unused cells, the controller has to use free (deleted) cells and it slows the write process.
