Disk space is also required for storing file system data structures. As data-file disk needs grow, consider increasing the amount of memory allocated to cache, as well. The ratio between disk cache and maximum file system size affects the performance of applications that retrieve data from a hard disk.
HPFS | Uses approximately 5% of available disk space. |
FAT | Uses up to 64KB for each partition. |
CD-ROM | Uses 0.1MB. |
For large file systems, add more memory to accommodate a larger cache size.
