All NTFS volumes contains a Master File Table (MFT) that is a record for everything stored at the drive. The more files you put at the drive the larger it needs to be. I usually expand the MTF at new drives to prevent MFT fragmenting. The program I am using, Diskkeper, call this process FragShield. The defragmentation program in Windows does not take care of MFT fragmenting, only file fragmenting.
DRI claims that the Drobo takes care of defragmenting. Does anyone know if they also handle MFT fragmenting? Should I run the FragShield or will it compromise my data?
There is also directory consolidation to consider. Does Drobo take care of it or should it be run separately?
