DAn,
Without looking at the source code..it'd be hard to be specific on
exactly why it's reporting what it is. For example, if the speed test uses
DOS calls, then the amount of buffers (addbuffer or mountlist buffers
parameter) can make a significant difference…you're not really reading
the drive…you're reading the buffers.
At the hardware level…if you're reading/writting the same sector
over and over again…cacheing on the drive would act the same…you'd be
working from the cache rather than the platters. One other thing could be
turning the clock on only while data is actually being transfered.
A simple way to test is to create a 1 meg file. Copy it to NIL:
and time it. Then copy it to another filename. I think you'll find it
takes significantly longer than a 2/3rds of a second.
