Repository Planning - NTFS

File System Formats

In addition to the storage stripe size alignment, as explained in the 

previous paragraph, the file system may also benefit from using a 

larger cluster size (or Allocation Unit Size). For example, during formatting of NTFS volumes, 

Allocation Unit Size is set to 4KB by default. 

To mitigate fragmentation issues, configure to 64 KB whenever possible.

Using "Large File" Switch for NTFS

A file size limitation can be occasionally reached on NTFS, especially on Windows Server with

deduplication enabled. This happens due to a hard limit reached on the file records size because of

the high level of file fragmentation. To mitigate the issue, we recommend to format Windows NTFS

repositories with the "/L" (large files) option.
