Correction:
No, the merge in SSIS is similar to the merge join in the db engine in that it has to physically sort (preceeded by a sort task) before you can merge the results.

...missed the w on Now.
as Champandew noted this is exactly like join types in t-sql.
there are these types there:
inner join --> like inner join in t-sql
full outer join--> like full outer join in t-sql
left outer join --> like let outer join in t-sql
there in no right outer join in merge join transform, but you can only change inputs and use left outer join to have right outer join .

merge join in SSIS- is it possible to say 'No thanks for physical sorting - just inner join the 2 OLEDB input and give it in any sort order"
