Best idea is to get any HDD benchmark/test apps (check that review sites is using for HDDs) and make testing.

Also replace the cable, if possible / use other MB connector.

I see people gettin over 130mb.sec with this drive, what is the deal?

from where are you copying the data to the drive, maybe the other hardrive is botlenecking, or the computer...

Good thing to notice. I can assure you that old drive can be so fragmented or have low level issues that can make it even below 1MB/sec. At first read test of files you copy must be performed. Most easy thing.

does drive indexing matter? my one drive is indexed while the other isnt. what about Legacy Bios USB in bios should i disable that?

It is probably that your 1tb drive is full and very fragmented like Vitaliy said, and if the system OS is running on this same drive and you have programs open it will not go higher than 40 to 50Mb/s: Try this, your motherboard has 2x blue Usb3 ports in the rear use these, use the Sd card reader and transfer a big file like 2 or 3Gb, directly to the new 2tb hard drive, also format it if you can in exfat just in case you need to use it in mac and pc, if not NTFS is ok for pc only. If the new drive is fresh formatted and it does not give the same speed of the card assuming it is a fast one it will go over 60Mb/s, I would advise you to find a friend and test the drive in other pc or mac with usb3 ports than you should know if it´s the drive or the motherboard, and from there take decisions.

Almost shure is the drive you are copying from, but you have to test it. Good luck

I know you are on Windows, but, this might be relevant:

I have a hackintosh running on very similar hardware and a seagate expansion drive (usb 3). I recall getting 90-100 MB/sec xfer speeds when I first set it up (all drives were new) 2 yrs. ago.

The Gigabyte boards I am told are great, but it took a little work to get USB3 running right for the Mac OS. For the Hackintosh: I had to turning something off in the bios and plug the USB 3 expansion ports into a certain plug on the motherboard (one connected more directly to the intel processor) as this is the only way Mac uses USB 3, directly off the intel processor. The rear USB3 ports have an internal hub chip made by Via Labs and on the Mac OS I couldn't get them to work reliably. I have found the aforementioned 2 expansion ports (mounted wherever you want, but probably the front of the case) are enough for me.

TonyMac gets pretty deep into this stuff. I also made the mistake of running an updater I shouldn't have trying to get the rear USB ports to run at USB 3 speeds and had to swap the motherboard. My build is 2 years old, so it maybe a different story now. However there is some good info on TonyMac about the bios settings that may help even in your set-up

"Gigabyte has a setting in the BIOS called xHCI mode" The explanation is here: http://www.tonymacx86.com/lion-desktop-support/57694-usb-3-0-gigabyte-uefi-motherboards-xhci-mode-explained.html

My path to solid USB3 is here. Some of it may help you in Windows or at least understand the motherboard better. Post #15: http://www.tonymacx86.com/general-help/90668-help-needed-usb-3-0-behavior-via-labs-vl811-usb3-hub-chip-ga-z77x-ud5h-rev-1-1-mobo-2.html#post834614

Get good advice - ignore ALL complex and personal remarks.

Make just two tests - writing of big random data (from memory) to new drive. Attach to different ports. If speed is low - make exchange and get new drive. Second test - make read test of original HDD (read same files you want to copy), if speed is low - make low level test and defragmentation. Period.

Thing that most people do - instead of simple things they start reinstalling drivers and OS :-)

By saying SSD you mean the 2Tb external usb3 drive?? Because SSD goes for Solid State Drive, and you never mentioned that before ;-)

If so and if you got above 60Mb/s to 100Mb/s in this new drive from the card reader the drive is OK, the hardware is ok, leave it alone.

Your problem is your internal hard drive, as stated in my first post, best thing to do would be backup your data, and format that drive, defragmentation like Vitaliy said is good but it takes forever and is only temporary, it wont last more than a few weeks maybe a couple of months and things will be the same, do a fresh install ( I do one every 6 to 8 moths at most, windows 7, 8 , 8.1 is a garbage collector).

As for a simple advice, for video editing is not recommended to use the system drive as work drive, it is very stressful and you don't have good results on the long term, it is best to buy a small SSD like 128Gb or + they are inexpensive now:

Install OS and programs on the SSD, update latest drivers from original brands and keep things clean.

It will last for a while you will notice fast speed overall, and be happy with USB3 tranfers :-)

OK so the speed is OK on your ext. drive.

Go with this good advice: Second test - make read test of original HDD (read same files you want to copy), if speed is low - make low level test and defragmentation. Period. Maybe format if you can.

Cheers

That is normal, one thing is sustained transfer speed and the other is random access speed, it changes a lot depending in the fragmentation, and physical disk limitations. Other thing is burst speed when the data is transferred super fast in normal disks like 300Mb/s and more got occasions when I transferred 3Gb files in less than 5 seconds, on the same disk that gives maximum sustained speed of 120Mb/s, it depend on the ram, memory allocated and size, hard disk status and if its full or empty, speed of the disks, etc.
