ALWAYS make small storage volumes - Size < 8TB

Modern data storage is a disk array, such as direct attached, SAN or NAS.  No matter what configuration or connectivity these disk arrays offer huge raw storage space.

Always partition a disk array into volumes smaller than 8 terabytes. You may end up with 50 or more volumes. This is OK.  Volume letters do not stop at Z:. The next drive letter after Z: is AA: then AB: etc...

The reason for small storage volumes is administrative speed, things like indexing, searches and most of all CHECK DISK. Check disk time to completion is dependant on the number of files on a volume. Running a check disk on a volume that is 16TB takes exponentially longer, than it does on an 8TB volume. 

If you have ever had to run a check disk on a full volume that is 10TB or larger you will already understand the pain involved here. You will not have the use of the volume for several days until the check disk is complete.

If your system currently has volumes greater than 8TB:

Start recording new data to another volume(s) now and let the largest volume(s) data start to age out. After the ageing period you can delete it and break the largest volumes into smaller sizes.
