Adding a 1Tb Samsung Hard Drive

I have been running my new build for around a month now and had no problems whatsoever with Vista 64.
Have tweaked the graphics card with an Arctic Cooling Accelero Xtreme 8800 and drastically brought the temperature down.
I have just taken receipt of a 1 Tb hard drive and wondered whats the best way forward.
Do I try to copy everything including the OEM version of Vista to the new hard drive or do I just transfer my files and keep the existing 320gb hard drive as the OS boot drive?

Whats everyones experiences about adding a hard drive?

Keep the OS on the 320gb drive and use the 1T drive for programs and data. If your OS fails and you need to reinstall at least your data will be safe. You may need to reinstall some files though as programs do link in to the registry. Another way of doing it is to use the 1T drive just for data. Pictures and music ect. This way it will be easy to back up when you want.
It also depends on the speed of the drive, if your new drive is alot faster than the old it would make sense to transfere everything to the new drive and sack the old drive or sell it on ebay.

Hi and cheers for the reply. Both are 7200rpm but transferring the job lot to the new HDD is an option , however as I have the OEM version of Vista I thought it was limited to one install?

I would do away with the 320gb, keep it as back up of your install & transfer everything to the new hdd. The samsung one is better in performace anyway i beleive.

I think you can get away with changing the hard drive, just not the MB
