HI All,

If I use the 2 USB ports on the front of my case I get a transfer speed of about 11.3MB/s.
If I use the 4 ports at the back of my case(onboard) then I get a transfer speed of about the same.
If I use the 4 ports connected via PCI(not Express) slot I get a tranfer rate of about 4.9MB/s.
The Card connected to the PCI slot is called a Silicon Image Sil 3x12 SATALink Controller Driver.

As far as I know I have the lastest drivers for my motherboard, USB devices and SATAlink controller.
Optimising external Drives and flash drives for performance doesn't make a difference either.

I have no idea why these transfer speeds are so slow and it's very frustrating.

Hopefully you guys can help.

Thanks in advance!

Check that you have the USB device set as follows.


To optimize your USB drive for performance:
1.Right click on the USB drive and select properties
2.Select the Hardware tab
3.Under All Disk Drives, highlight your USB drive and select Properties
4.Select the Policies tab and select Optimize for performance.
5.Press OK twice, and your transfer speeds should increase dramatically

Hi Mark,

I mentioned in my post that it never made a difference.

Thanks

Ooops, so you did.

Transfer speeds are complained about quite often but other than the optimization setting there is nothing I know of that will make any difference. All too often it is just the way the motherboard is designed.

Other helpers may be able to make other suggestions.

IF you use ports for longer times they tend to slow down i dont know why . My front ports have the same problem .Back ports are fine.

I'm going to take a wild shot here since you bumped. But I would take a look at BIOS. Sometimes there are settings for the slot timing and that could be related to transfer speeds.

Hi Elvandil,

I looked in the BIOS and didn't see anything to that effect unfortunately unless I didn't know it when I saw it ;-) Any other ideas?
