Very Poor copying speed on USB 3.0

S

I have Purchased New Gigabyte Mobo,Model is B75M-D3H.I have intel core i3 2120 2'nd generation CPU.My mobo has2 3.0 USb ports and 2 2.0 USB ports.
I have installed Windows 8 Pro.I am very much Disappointed with my USB file copying performance.I have 2 TB Seagate Protable Hard Drive which Supports USB 3.0
When I copy a file of 1.0 gb from my pc to hard drive or viceversa it take more than 30 minutes to get copy,The copying process starts with good speed around 30mbps but it gradually gets decreased and one stage comes where I get max 300kbps whcih I even lesser than my Internet Transfer Rate :cry:

.I am very much irritated with this problem , I tried Tera Copy But didn't get any results,even on my usb 2.0 m facing the same issue.
I tired by updating my mobo drivers but even after that nothing has changed.
Please Guide.

Are you sure you installed proper drivers for 3.0 ?

What's the cache size of your hd ? Mine usb3 speeds were quite low on an hd with 2mb cache, but when I upgraded to 32mb cahe drive, speeds got to 70-80mbps from 20-30mbps

win 8 does NOT needs any USB 3.0 drivers AFAIK .. Op may need to update his mobo's bios to the latest version.

which cabinet you are using? is it has usb 3 ports?

How to change the cache size? it that can be done without formatting the drive?

I have 2 USB 3.0 In the Front panel and 2 on the mobo + there are 2 USB 2.0 on mobo. and all of them are working slow.

^ hard disk cache size cannot be changed, it's a hardware property not software. Different models have different cache sizes.

@ OP - some questions :

1. Did you check the USB ports speed with another device ie pen drive/or another extrenal HDD ?
2. The extrenal HDD workking fine on other pc's and there's no bad sector in this.
3. Make sure your USB port settings are correct in bios .. if possible do post the screenshots here.
4. If possible format and re-install the OS.
