Because the data buffer size equals the tape I/O size, the value specified in 
SIZE_DATA_BUFFERS must not exceed the maximum tape I/O size supported by the 
tape drive or operating system. This is usually 256 KB or 128 KB.

For Digital Linear Tape (DLT) drives, the number that seems to give the best 
performance for SIZE_DATA_BUFFERS is 65536. Further performance improvements 
can be achieved by increasing the value in the NUMBER_DATA_BUFFERS file.

What is the optimum for STK 9940B?
