Some fellow Atari user had a faulty hard disk drive, and in an effort
to help him, I wrote some diagnostic software which checked a
hard disk for low-level read errors - this is how CHECKHD was
born. Later, the software evolved by adding benchmark code.
Back in those days, I wrote mass storage device
reviews for the ST-Computer magazine - I simply needed a way to
compare the performance of all those hard disks.
So CHECKHD is a hard disk checker and benchmark program. It was part of
, but was also distributed (in a special version)
along with certain Vortex hard drives.
What was cool about this software was that it tried to closely match
the methods which hard disk makers used to measure access times
and transfer rates, by coding as close to the metal as possible.
The idea was to establish
a low-level benchmark to check the speed of new hard disks. These days,
is probably closest in spirit to CHECKHD.
For my reviews, I also used higher-level tests (such as file copy
tests). So we used CHECKHD to find out what the hardware could do,
and higher-level tests to find out how much performance was lost
on the way through the disk driver software stack (disk driver,
BIOS, GEMDOS, application code).

For your amusement, I even found a few old benchmark results:
