Samsung 64GB SSD (SLC) from Lenovo ThinkPad X300
Code:
/dev/ad4
	512         	# sectorsize
	64023257088 	# mediasize in bytes (60G)
	125045424   	# mediasize in sectors
	124053      	# Cylinders according to firmware.
	16          	# Heads according to firmware.
	63          	# Sectors according to firmware.
	SE815K0462  	# Disk ident.

I/O command overhead:
	time to read 10MB block      0.118183 sec	=    0.006 msec/sector
	time to read 20480 sectors   1.747203 sec	=    0.085 msec/sector
	calculated command overhead			=    0.080 msec/sector

Seek times:
	Full stroke:	  250 iter in   0.046148 sec =    0.185 msec
	Half stroke:	  250 iter in   0.045511 sec =    0.182 msec
	Quarter stroke:	  500 iter in   0.091325 sec =    0.183 msec
	Short forward:	  400 iter in   0.072594 sec =    0.181 msec
	Short backward:	  400 iter in   0.073381 sec =    0.183 msec
	Seq outer:	 2048 iter in   0.234476 sec =    0.114 msec
	Seq inner:	 2048 iter in   0.231109 sec =    0.113 msec
Transfer rates:
	outside:       102400 kbytes in   1.148034 sec =    89196 kbytes/sec
	middle:        102400 kbytes in   1.156049 sec =    88578 kbytes/sec
	inside:        102400 kbytes in   1.178575 sec =    86885 kbytes/sec

Linux is not UNIX! Face it! It is not an insult. It is fact: GNU is a recursive acronym for “GNU's Not UNIX”.
