I think you more or less compare apples with pears when comparing TOS and
NetBSD disk throughput. Some of the difference are caused by:
    - Memory protection between processes and proces/kernel. This means
      that all I/O will generate an additional copy operation between
      kernel and user space.
    - Driver structure. The NetBSD driver has to be interrupt driven,
      otherwise the system won't be multitasking.
    - There are always some other processes that interfere with the
      benchmark process when running it under NetBSD.

So the 1.3 Mb you mention for TOS is probably unreachable with NetBSD...

I have no idea if the figures you got are reasonable.
