PS files can be created on tapes while the VSAM files

while no such facility exists for PS files.

Storage capacity of VSAM file is more than that of NON-Vsam file.
in VSAM if tale 1 trk => 1+1*122=123 extent allocation.
where as in NON-VSAM, for 1 trk => 1+1*15=16 extent allocation.

Answer / vivek
VSAM files are used when we want to store data based on
some key fields(Eg: KSDS)
access method is indexed.
NON VSAM files like PS are used when we want to store data
which is not unique and also the access is sequential.
