Measured by performing multiple accesses which refer to reads of data blocks over the whole
area of the media from 0 (h) block to 1E7725(h) (4.089 billion byte:87% of total area) block
more than 3,000 times. Includes positioning, setting, latency time, and ECC implementation
time (if required).
3
Measured by performing multiple accesses which refer to reads of data blocks over the whole
area of the media from 00 min. 02 sec. 00 frame to 60 min. 01 sec. 74 frame (552.96 million
bytes:87% of total area at linear velocity of 1.3 m/s) more than 3,000 times. Includes positioning,
setting, latency time, and ECC implementation time (if required).
4
Measured by performing multiple seek which refer to seeks of data blocks over the whole area
of the media from 0 (h) block to 1E7725(h) block more than 3,000 times. Includes positioning,
setting time which has the same definition as HDD.
5
Measured by performing multiple seek which refer to seeks of data blocks over the whole area
of the media from 00 min. 02 sec. 00 frame to 60 min. 01 sec. 74 frames more than 3,000 times.
Includes positioning, setting time which has the same definition as HDD.
6
Measured by performing maximum accesses which refer to reads of each data block of 0 (h)
block and 1E7725(h) block alternately more than 100 times. Includes positioning, setting,
latency time, and ECC implementation time (if required).
7
Measured by performing maximum accesses which refer to reads of each data block of 00 min.
02 sec. 00 frame and 60 min. 01 sec. 74 frames alternately more than 100 times. Includes
positioning, setting, latency time, and ECC implementation time (if required).
