I am going to get a 1TB hard disk.

I will be storing 1080p or 720p movies, high-bitrate music and pictures in it. I use my PC 90% of the time only to play/listen/see those.

I am running out of space in my current HD so I am getting another one.

My specs are 2.7GHz Dual Core, 512MB GeForce 9400GT, 2GB DDR2 RAM and all the proper matroska codecs/players. I guess that is enough to play 1080p movies withough a glitch, given an ideal hard disk.

I've read about proper partitioning giving performance improvement etc.. I don't want my hard disk to be the bottleneck.

Can someone tell me whether I should partition my 1TB hard disk into many drives? If I should, what is the ideal size of each partition?

Smooth playing of movies is very important to me. Once I start filling up the disk, there is no turning back. So I want to get it right before I start.

Thanks.
