Which Western Digital Caviar Hard Drive Performs Better: Blue Or Green Or Black And Why?

Hi, I had bought a Gateway DX 4831 desktop computer which comes with Intel Core 13-530, 6 gig of memory and 1 tara-bytes green caviar hard drive from western digital with 32, which is my three main focus of get this desktop.
About a years and a month later from the date later, the hard drive begin to have problem. First, while I was doing my design works, the blue-screen pop-up with an error message stating that there is a conflict with some of my hardware or conflict with a virus infection. Now, I know a thing or two about computer and I know there is no virus on my 1 tara-bytes hard drive because I use Norton Internet Security 2009 60 days trails at the time because it come pre-loaded with my computer and it detect no virus with full system scan.
So I let the machine rebooted and every loaded fine. One day, when one of design programs “Adobe Illustrator CS5” won’t let me created a new document, I decide to a system recovery. First, I notice that recovery time is longer than usual so I decide to wait and see what happen. When I loaded the second recovery disc in, when it reach to 17, 22, 65, and sometime 66% percent, an error code 1117 – io device error pop-up and eject the second recover disc.
First I thought it might be the cable but then I replace my 320 gb blue caviar hard drive from western digital and the recovery was a success with only 4 minutes where the 1 tara-bytes green hard drive take 17.03 minutes and some longer but still fail. So I decide to get BestBuy Geek Squad a called and he asks me to bring my computer for a quick look.
First, the Geek Squad told to clone the hard drive with “Acronis True Image software” or he can do it for which will cost me $160.00 and it may take 20 or 24 hours. I just refuse to let the Geek Squad to course me $160.00 and decide to do the hard drive clone myself I did it before when the 1 tara-bytes hard drive won’t boot-up.
I know it not a virus infection because the hard drive does boot-up but it won’t let me do a complete recovery.
When I set both hard drive “320 gb blue caviar and 1 tara-bytes green caviar” but this time, the clone don’t works so I decide to replace my 1 tara-bytes by buying a new 1 tara-bytes hard drive.
Before I make the purchase, I want to know which one is better, Blue Caviar or Green Caviar or Black Caviar. If I decide to fix the problem, how can I fix it. I was thinking doing a bad sector disk check, or try to do the hard drive clone with 1 tara-bytes as the main drive. I ask one of the BestBuy Geek Squid and they said the Black is a better choice but if money is my problem, the green is better and faster than the blue caviar.
So do you think I should buy a new hard drive or try to fix the problem myself by doing a bad sector disk check on the 1 tara-bytes green caviar hard drive.
