video rendering

[rizvii]

i have two HDD in my system one is 160 GB and the other is 80 GB both are sata drives. I use pinnicle ultimate 12. should i use separate HDD for rendering will it speed up the operation. And further what should be the size of xp partition for the same purpose

Partitioning doesn't do a lot for speed. It can help reduce fragmentation, but writing from one partition to another on the same disc is slower that writing from one physical drive to the other. My systems all have a smaller system drive (physical) - typically 80MB on older machines and 120 - 160 on newer machines - and multiple larger HDDs for data and projects.

How much of a difference it makes depends on what you are doing. If you are doing straight encodes or direct stream copies, you will gain some advantage. If you are doing heavy processing of the video then IO won't be the bottleneck, the CPU will, so you gain virtually nothing.

thanks . and is it true that smaller HDD are faster than larger HDDs

Not necessarily, no

Read/write speed tracks rotational RPM more than capacity. Speed is reduced when the disk needs to seek. Thus defragmentation can speed the disk allowing a continuous write.

Rendering is usually CPU limited more than disk speed limited.
