Due to some diligent searches, I gathered the UNofficial answers to these questions:
Why not talking about Santa Claus?
Which filesystem would he run to store the database of all the good (and bad) kids?
Would he use basic or dynamic disks?
The "who cares" news are that Santa Claus does NOT use dynamic disks.
The bad news are that he stores the good kids names on a FAT12 formatted USB stick, while the names of bad ones are in a server farm below the North Pole occupying several acres and hundreds of petabytes.
The good news are that he used NTFS encryption on the latter and he can't remember the password, and that Mrs.Claus washed the pair of trousers where he forgot the stick.
So, no matter if you are among the good or the bad, you can have a Merry Christmas!
My best grumpy wishes to all members:
