New Build, CD Drive Problems

Hello community. I have recently built my first PC and I think there are problems with my CD Drive.

Specs:

i5 3570k
8GB RAM
GTX 670
ASROCK Z77 Extreme 4
Windows 7 64bit
and
Samsung SH-222BB

Right now I am installing BF3 through the disc only at 2.5MB/s! That is incredibly slow. My old PC installed it with around 15MB/s I think.

my Optical drive is in a SATA 2 3Gb/s port but its using this old blue Sata Cable from one of my earliest computers. I heard that the Cable actually doesn't affect speed.

Also during my Windows 7 installation, Expanding Windows 7 Folders was also very slow, took like 20 mins

What should I do?
