Sql Server int vs nvarchar comparison on performance?

Question

For you database design/performance gurus out there.

I\'m designing a table, I have the choice of either use int or nvarchar (128) for a column, assume space is not

Answer 1

The main issue with performance with this is the size of the field - an int is 4 bytes, whereas an nvarchar(128) will be 254 bytes.

All of this needs to be manages by SQL server, so managing an int will be much faster than an nvarchar(128).
