There can be if you code for just what you expect. QSAM does multi-buffer I/O for you, with BSAM you have to issue multiple WRITE or REAAD commands and do a WAIT, not to mention having to block or de-block the buffer, which can be a real pain for VBS files.
It really depends on how much you are processing and how often you are doing it to determine if the amount of time you are going to spend on developing it makes it worth it. Using QSAM with GET LOCATE (as long as you aren't processing VBS files) and a reasonable BUFNO of 10 or more is going to get you close to most BSAM applications. GET or PUT with the MOVE option is the easiest to code for.
