Samsung HD204UI 2T drive -- Why is it so very slow!

I just bought a "SAMSUNG EcoGreen HWIC-2T   F4 HD204UI 2TB 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive" 

I ran:

mkfs.ext2 /dev/sdc2

on a 1.8t partition and it took nearly 8 hours.

I then copied 14G over to it and that took 2hours. 

Does this sound normal for this drive?  I know it's only 5400 rpm, but I am using this as a backup drive and from the reviews I've read thought the performance would be fine.

I need to determine if this is faulty or just a bad spec'd drive.  Any help appreciated.

Even if the test comes up clean, I'd note that amount of time it took to run and see if you can get Samsung to RMA/Exchange it anyway. There's definitely something wrong with that drive, taking that long. It is always easier to just get an exchange than try to run some software that supposedly fixes the issue... Honestly I'd rather have a clean disk than one WS-X45-SUP7-E   that was damaged and may just get worse.
