• Don’t do this if you use compression :-)
  FSUTIL behavior set disablecompression 1

• Don’t do this if you use Microsoft built-in encryption!
  FSUTIL behavior set disableencryption 1

• This one interferes with some backup and file-sync systems.
  FSUTIL behavior set disablelastaccess 1

• This will interfere with very old software, or software whose updates do not comply with Microsoft’s recommended practices, especially involving DOS-style short filenames.
  FSUTIL behavior set disable8dot3 1

This one may decrease speed a tad, but should increase reliability. Does not work with system drives, it is unclear as to why.
FSUTIL resource setconsistent E:\

This one resets NTFS transaction logs at reboot, this can eliminate many issues of filesystem slowdown over time which have to do with a kind of corruption which CHKDSK does not catch.
fsutil resource setautoreset true c:\

This one reserves more disk space for file tables; can be 1, 2, 3, or 4. Makes handling of large quantities of files more efficient. Unfortunately only helps for partitions created after the setting is made.
