Cruzer Micro 2 GB USB stick:
Code:
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <SanDisk U3 Cruzer Micro 2.18> Removable Direct Access SCSI-2 device
da0: 40.000MB/s transfers
da0: 1959MB (4013713 512 byte sectors: 255H 63S/T 249C)
Code:
# diskinfo -c -t /dev/da0
Password:
/dev/da0
        512             # sectorsize
        2055021056      # mediasize in bytes (1.9G)
        4013713         # mediasize in sectors
        249             # Cylinders according to firmware.
        255             # Heads according to firmware.
        63              # Sectors according to firmware.

I/O command overhead:
        time to read 10MB block      0.604066 sec       =    0.029 msec/sector
        time to read 20480 sectors  20.573283 sec       =    1.005 msec/sector
        calculated command overhead                     =    0.975 msec/sector

Seek times:
        Full stroke:      250 iter in   0.254135 sec =    1.017 msec
        Half stroke:    diskinfo: read error or disk too small for test.: Input/output error
