[quote GGD]Can anyone quote any documentation from Apple that states that you need to leave 10-15% of the space on a drive free, and the reason why.
Mac OS X uses free disk space for at least three things:
1. the virtual memory 'backing store'
2. hotfile optimization and defragmentation
3. sleepimage storage
- The more applications you run simultaneously and or the less real RAM you have, the more disk space that will be consumed for 1.
- Larger disks mean more files which lead to a higher requirement for 2.
- The more real RAM you have the more disk space you need for 3. If you have 4 GB of RAM, you'll need 4 GB of free disk space for the sleepimage.
