Advantages :

No internal fragmentation
May save memory if segments are very small and should not be combined into one page.
Segment tables: only one entry per actual segment as opposed to one per page in VM
Average segment size >> average page size
Less overhead.



Disadvantages :

External fragmentation.
Costly memory management algorithms.
Segmentation: find free memory area big enough.
Paging: keep list of free pages, any page is ok.
Segments of unequal size not suited as well for swapping.
