DISKINFO(8) FreeBSD System Manager's Manual DISKINFO(8) NAME diskinfo -- get information about disk device SYNOPSIS diskinfo [-ctv] disk ... DESCRIPTION The diskinfo utility prints out information about a disk device, and optionally runs a naive performance test on the device. 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, stripe size, stripe offset, firmware cylin- ders, firmware heads, and firmware sectors. The last three fields are only present if the information is available. If given the -v option, the fields will be printed one per line with a descriptive comment. The -c option triggers a simple measurement of the I/O read command over- head. The -t option triggers a simple and rather naive benchmark of the disks seek and transfer performance. HISTORY The diskinfo command appeared in FreeBSD 5.1. AUTHORS Poul-Henning Kamp BUGS There are in order of increasing severity: lies, damn lies, statistics, and computer benchmarks. FreeBSD 11.1 November 9, 2004 FreeBSD 11.1
