Abstract: Many computer users are interested in the actual data
transfer rates achieved when real controllers and disks
operate with a real operating system, doing real data
transfers as compared with the data transfer rates claimed
in manufacturers' literature.
 
Thirteen test programs were written to exercise the various
operational parameters of a disk, while doing the type of
transfers that might be observed in real-world applications.
These test programs were run on a wide variety of disks by
many Digital Equipment Corporation end-user sites and a few
manufacturers.
 
The test programs were run on disks ranging from RX01
through the more common cartridge disks, on to some
relatively large and exotic Winchester and memory disks, and
even on an Ethernet virtual disk.
 
The results are presented in tabular form so that direct
comparison is possible.  The results of this project are
very interesting to those interested in real-world disk
performance.
 
The results were published in the Fall 1984, 1987, 1988, and
1990 Symposium Proceedings.
 
Restrictions: Operating System RT-11 V5 or later is required if DU
device.  RTEM is
required to run under Operating System VMS.
