Please, I DON'T mean to cause another "My computer is better than yours" war,
but I couldn't let this just slip by.

Amiga hard drive performance, depending on the particular setup, can be
very fast.  Actual disk throughput of over 800K/sec has been reported, and
500K/sec is common.

The performance depends on the file sytem (the Fast File System or the
Original File System), the controller type (ST502 or SCSI), the specific
contorller chosen, the number of buffers, the CPU utilization, the average
track-to-track access time of the hard disk itself, and other factors.

Now, if you are talking about the Amiga running under the Original File System,
then it would be woeful to just barely beat it in performance, because the
Original File System is VERY slow.  However, it isn't used much anymore.

If you know of someone who currently has an Amiga with poor hard drive
performance, chances are that either he has a very poor controller, has
allocated VERY few buffers, or is running under the old file system.  If you're
basing your opinion of Amiga hard disk speed from a past observation, please
take another look.


In summary, the performance of the Amiga hard disk system, using the Fast File
System, is far from woeful.  In fact, it's very fast.
