HARD DRIVE TEST RESULTS

    The following tables were obtained using Core's Hard Disk Performance  
Testing Program Version 2.7 on a Tandy 1000 SX, equipped with a 20 Mb Seagate 
ST-225 and Western Digital Controller. The computer was using Tandy's MS-DOS 
3.2. Two tables are provided one for each of the 1000 SX's clock speeds. The 
test were conducted using a 34 Kb tranfer block, and using all 611 cylinders 
of the hard drive. Please direct questions or comments to James Raffeld
