ad0: 114473MB <Hitachi HTS541612J9SA00 SBDOC70P> at ata0-master SATA150 | Laptop 2.5"

Code:
/dev/ad0
	512         	# sectorsize
	120034123776	# mediasize in bytes (112G)
	234441648   	# mediasize in sectors
	232581      	# Cylinders according to firmware.
	16          	# Heads according to firmware.
	63          	# Sectors according to firmware.
	ad:SB2D41E4CGEKKE	# Disk ident.

I/O command overhead:
	time to read 10MB block      0.287116 sec	=    0.014 msec/sector
	time to read 20480 sectors   2.480988 sec	=    0.121 msec/sector
	calculated command overhead			=    0.107 msec/sector

Seek times:
	Full stroke:	  250 iter in   6.031056 sec =   24.124 msec
	Half stroke:	  250 iter in   5.037848 sec =   20.151 msec
	Quarter stroke:	  500 iter in   8.506920 sec =   17.014 msec
	Short forward:	  400 iter in   3.550424 sec =    8.876 msec
	Short backward:	  400 iter in   2.049560 sec =    5.124 msec
	Seq outer:	 2048 iter in   0.291115 sec =    0.142 msec
	Seq inner:	 2048 iter in   0.295479 sec =    0.144 msec
Transfer rates:
	outside:       102400 kbytes in   2.690707 sec =    38057 kbytes/sec
	middle:        102400 kbytes in   3.281864 sec =    31202 kbytes/sec
	inside:        102400 kbytes in   5.554393 sec =    18436 kbytes/sec
