Nothing to do with swapspace. You need 32 KB-Chunks of
continous memory in the lower 16 MB as DMA-Buffers. Now,
with 4 KB page size that is not guaranteed, but if you hug a
lot of memory[1] (forcing some pages to swap out, and some
buffers to get freed), and the release the memory used[2],
you stand a much better chance.

For a lot of tape drives (TR-3), 1000 MBit/s is the lowest
possible rate you can use. Else you'd have to drop back
to TR-2, halving the capacity. For the Ditto Max (Pro) the
minimum rate is 2000 MBit/s. So be sure to check and test that.
(From memory, and I have been known to be wrong a few times :-)

[1] In your case 32 MB
[2] which is exactly what swapout does.
