In a dual-drive system, the system manufacturer will install a small SSD primary drive (C:) for the operating system and apps, and add a larger spinning hard drive (D: or E:) for storing files. This works well in theory; in practice, manufacturers can go too small on the SSD. Windows itself takes up a lot of space on the primary drive, and some apps can't be installed on other drives. Some capacities may also be too small. For example, you can install Windows on a SSD as small as 16GB, but there will be little room for anything else. In our opinion, 120GB to 128GB is a practical minimum size for the C: drive, with 256GB or more being even better. Space concerns are the same as with any multiple-drive system: You need physical space inside the PC chassis to hold two (or more) drives.

Example:
DECLARE @FirstName AS VARCHAR ( 50 ) = ‘BASAVARAJ’
SELECT @FirstName AS FirstName ,
DATALENGTH ( @FirstName) AS
Length

Result:
FirstName Length
BASAVARAJ 9 It takes 2 bytes per Unicode/Non-Unicode character.
Example:
DECLARE @FirstName AS NVARCHAR ( 50 ) = ‘BASAVARAJ’
SELECT @FirstName AS FirstName ,
DATALENGTH ( @FirstName ) AS Length

Result:
FirstName Length
BASAVARAJ 18 Optional Parameter n range Optional Parameter n value can be from 1 to store maximum 8000 Non-Unicode characters. Optional Parameter n value can be from 1 to store maximum 4000 Unicode/Non-Unicode characters If Optional Parameter n is not specified in the variable declaration or column definition If Optional parameter value n is not specified in the variable declaration or column definition then it is considered as 1.
Example:
DECLARE @firstName VARCHAR = ‘BASAVARAJ’
SELECT
@firstName FirstName , DATALENGTH ( @firstName ) Length

Result:
FirstName Length
B 1 If Optional parameter value n is not specified in the variable declaration or column definition then it is considered as 1.
Example:
DECLARE  @firstName NVARCHAR = ‘BASAVARAJ’
SELECT
@firstName FirstName , DATALENGTH ( @firstName ) Length

Result:
FirstName Length
B 2 If Optional Parameter n is not
specified in while using
CAST/ CONVERT functions When this optional parameter n is not specified while using the CAST/CONVERT functions, then it is considered as :
DECLARE  @firstName VARCHAR ( 35 ) =
‘BASAVARAJ PRABHU BIRADAR INDIA ASIA’

SELECT  CAST ( @firstName AS VARCHAR ) FirstName ,
DATALENGTH ( CAST ( @firstName AS VARCHAR )) Length

Result:
FirstName Length
BASAVARAJ PRABHU BIRADAR INDIA 30 When this optional parameter n is not specified while using the CAST CONVERT functions, then it is considered as :
DECLARE  @firstName NVARCHAR ( 35 ) =
‘BASAVARAJ PRABHU BIRADAR INDIA ASIA’

SELECT  CAST ( @firstName AS NVARCHAR ) FirstName ,
DATALENGTH ( CAST ( @firstName AS NVARCHAR )) Length

Result:
FirstName Length
BASAVARAJ PRABHU BIRADAR INDIA 60 Which one to use? If we know that data to be stored in the column or variable doesn’t have any Unicode characters. If we know that the data to be stored in the column or variable can have Unicode characters. Storage Size Takes no. of bytes equal to the no. of Characters entered plus two bytes extra for defining offset. Takes no. of bytes equal to twice the no. of Characters entered plus two bytes extra for defining offset. As both of these are variable length datatypes, so irrespective of the length (. optional parameter n value) defined in the variable declaration/column definition it will always take the no. of bytes required for the actual charcters stored. The value of n defines maximum no. of characters that can be stored.
