Working with Windows NT and need to determine disk space requirements? Keep the following in mind:

  • Windows NT operating system requires about 100 MB of disk space itself.
  • The total amount of recommended paging space is one and a half to four times the amount of physical memory. However, the minimum recommended page file size for a small memory system is 30 to 40 MB.
  • Add the disk space requirements of the application programs you plan to run, including permanent storage for their executable and dat files and any execution scratch space they may require.
  • Take into account any fault tolerance features you plan to use, which will increase the disk space needed to create a filesystem of a given size.
