The primary disadvantage of VSAM is that it cannot be stored on TAPE Volume. In case you are handling huge amount of data, many cyclinders will have to be allocated which is not cost-effective compared to flat files which can be saved in tapes..

Make a choice between vsam and flat files based on the amount of data, mode of accessing etc..
