By default NTEXT stores the text value in the LOB structure and the table structure just holds a pointer to the location in the LOB where the text lives. I converted one column at a time and a simple select query which took 4 secs on the unchanged table still took 4s until I had changed all the columns using ntext to nvarchar, and then it came down to 3secs avg

From some blogs, I understand that if records have this column length less than 8000, SQLSERVER stores the data in side the row (based on option setting) and hence the performance will be better. If you get this working properly with this new table you have some possibilities to optimize it even further (well, you have some these options with a single table also)

When I am trying to update any column after the 310th (where as all starting 309 columns having some value) it gives error: Cannot create a row of size 8061 which is greater than the allowable maximum row size of 8060.
