The DAT engineer said: "The bigger the better." Via HPFOPEN, MPE supports a 16K buffer, which is ok for DATs. STORE/RESTORE can go up to 32K. The basic criteria is to keep the tape streaming.

Yes! For DAT, the bigger the better. 32K will be good! Particularly for the compression drives, small blocks do not compress efficiently.
