Transfer speeds very slow

[jr8801]

I have a Samsung spinpoint f3 and i am trying to transfer some stuff to a usb 3.0 Goflex 1.5tb drive. I started at 325 mb/s and quickly stumbled to 14 mb/s.... I transferred the same data to a usb 2.0 drive and got 30 mb/s constant.

I have a gigabyte GA-Z68A-D3H-B3 motherboard. which has two usb 3.0 inputs.

Anybody know why im getting so slow of transfer speeds to my usb 3.0 drive.

Could be. My usb 3.0 is the first NEC controller and I think Asus laptop also use NEC controller. I am not sure about the controller use in your mobo. May be start a new thread on the mobo section of forum and ask someone there.

Alright thanks Pyree, i searched for a couple hours about the firmware problem. It seems i have the latest most up to date firmware for the F3. Tried the transfer test again First from
3.0-F3=slow
F3-WD=Average (65mb/s)
WD-3.0=Slow
WD-F3=Average
F3-3.0= slow.

I also have a macbook pro with firewire 800 port, so i plugged a firewire adapter (that i previously bought for this drive from Seagate).
FW800--MBP=70 mb/s
MBP--FW8= 70 mb/s

Lastly I tried on my Girlfriends Asus Laptop (3.0 enabled with same drivers as my rig).
3.0--Asus= 75-85 mb/s (little fluctuation but generally pretty steady at 80mb/s)
Asus--3.0= 74-99 mb/s (started out slow eventually got fast then slowed down a little)

Could this may be not a problem with a drive at all rather the mobo's 3.0 ports. on newegg some of the reviews say the the usb 3.0 port is "hit and miss".

Any insight would be great especially if someone has had the GA-Z68A-D3H-B3 mobo.

I have a gigabyte board as well the 970a-d3 , and I experiance the slow transfer as well, although it only started about a year after I had the board .... so did some searching Lots of searching and am still searching which explains how I ended up here. anyway, My problem has got so bad that when I transfer 2 4 gig files to my flash drive my whoe system starts to become sluggish ...at first I thought harddrives were failing(replaced) well didnt work, then I though flash drive was failing(replaced) didnt work, then someone said PSU(replaced) didnt work and getting pissed now, so now I find out it actualy the southbridge on the motherboard that is most likely failing. and with some quick adjustments to my google searches I find that gigabyte boards are becoming known for this. well glad it lasted a year for me at least so guess Ill go by another mobo from another maker. I cant say for sure that its the same problem you have man but it sure sound familiar so hope this helps and good luck.

Try this:
Switch off USB Legacy in BIOS and try your USB speed.

!!! WARNING !!!
BUT:
be sure to have a PS2 keyboard at hand before you do so,
you cannot get into BIOS with an USB keyboard when USB Legacy is switched off.
