   Why is because the DLTs are designed to process large chunks of data.
  At 512-byte blocks, it's going erk-erk-erk-erk instead of zoom. ;)

   I should mention that the speed of your SCSI bus might come into play
here. If the DLT is attached to, say, an Adaptec 1520, there's not much
lovin you can give it.

   Whether you need to set or reset the blocksize is dependent on the
operating system and what tools you're using for writing & reading.
With nearly any "modern" streamer, a variable blocksize will give the
best overall performance.
