Diskinfo is a small program to access the basic properties of a disk device:

sectorsize, mediasize etc.

It also contains a small and naïve benchmark which reports on seek
and transfer performance.

+.Sh SYNOPSIS
+.Nm
+.Op Fl v
+.Op Fl t
+.Ar disk ...
+.Sh DESCRIPTION
+The
+.Nm
+utility prints out information about a diskdevice and optionally runs a naïve performance test on the device.
+.Pp
+If given no arguments the output will be a single line per specified device
+with the following fields:  device name, sectorsize, media size in bytes,
+media size in sectors, firmware cylinders, firmware heads and firmware sectors.
+The last three fields are only present if the information is available.
+.Pp
+If given the
+.Fl v
+option, the fields will be printed one per line with a descriptive comment.
+.Pp
+The
+.Fl t
+option triggers a simple and rather naïve benchmark of the disks seek
+and transfer performance.
