Hum,
You can allocate any amount of memory...(
see my link about virtual memory etc)
It isn’t tied into the size of the HD partitions....(
it`s better to choose your partition size on your needs rather than the computers memory needs)
The clusters are just `unit` blocks on the cylinders. And only are important to the speed and physical space they require...
"By partitioning, you decrease wasted space by files using larger clusters. If you partition a 20GB drive to one 20GB partition, you'll end up with 16KB clusters. If you split it to say two 10GB's you'll use 8KB clusters. Less than 8GB's will give you 4KB clusters.
Example:
2KB file on a 4KB cluster = 2KB's wasted space.
2KB file on 8KB cluster = 6KB's wasted space.
2KB on 16KB cluster = 14KB's wasted.
Here is a chart for FAT32:
512MB-8,191MB = 4KB clusters
8,192-16,383MB = 8KB clusters
16,384MB-32,767 = 16KB clusters
32,768- greater = 32KB clusters"
