Any advice appreciated!

I'm setting up a second drive (80 G)for capture and data so.... there will be several partitions on this drive. My OS partitions (on a separate drive) use the 4K cluster size.

1. If my capture partition is about 50 G, what would be the best cluster size? Would it be better to match the 4K size of my operating system or use the 32 or 64K size?

2. On this second drive besides the dedicated capture partition, I will have several small partitions for things like drive image, other data. Would I get better data transfer rate if I place the capture partition at the beginning of the drive? Which part of the drive is generally the fastest?

thanks for your help...kristin
