The issue is not the backing disk as using the same benchmarking
technique (see bellow) I get around ~270 MiB/s from the actual
`/vicepX` files.

The technique is simple (i.e. list all files, randomize them, and then
`cat` them 128 at a time to `/dev/null`):

  find . -type f | sort -R | xargs -P 64 -n 128 -- cat > /dev/null
