[Coco] hard disk performance

[Robert Gault]

Discussing test results is pointless unless the test is specified 
precisely and all reported test adhere to the same protocol.

So, to propose a specific test, get Megaread from the NitrOS-9 
distribution and transfer it to your Coco hard drive system. Then 
execute the command sequence
load date
date t; megaread </h#@; date t
where # is the number of the drive under test.

Results on my Ken-Ton scsi adapter, 6309 modified RGB-DOS driver, and 
Segate ST-296N hard drive are
Fri Sep. 26, 2008 07:12:32 PM
Fri Sep. 26, 2008 07:13:57 PM
for one pass of megaread. That should be ~12k/sec.

The same test using an Adaptec 4000A board with a Tandon TM-252 gave
11.4k/sec.

My modified driver uses the TFM command to transfer data.
