I just tried reading a 10 MB large file sequentially on our Encore
Multimax. The disk is a NEC something (655 MB formatted) and it is
using the *old* I/O system from Encore (based on single-ended, async
SCSI). I got well over 900 KB/sec throughput thru the BSD FFS on a
non-striped partition under System V.
