Partition offset and allocation unit size of a disk for SQL Server

SQL Server performance is dependent on the server resources available and disk performance is probably the most important resource. To maximize disk performance for SQL Server, I've always been told that the drive's partition offset must be set to 32K and the allocation unit size set to 64K for partitions that hold data and 8K for partitions that hold logs. How do I find out the allocation unit size and partition offset for my drives?

Creating a JSON Document IV

I have this data in a table called dbo.NFLTeams

TeamID  TeamName       City             YearEstablished
------  --------       ----             ---------------
1       Cowboys        Dallas           1960
2       Eagles         Philadelphia     1933
3       Packers        Green Bay        1919
4       Chiefs         Kansas City      1960
5       49ers          San Francisco    1946
6       Broncos        Denver           1960
7       Seahawks       Seattle          1976

SELECT

  json_objectagg(city : TeamName)
FROM dbo.NFLTeams
GROUP BY  YearEstablished;
