1.3 General caution

! Do not apply force to the top cover (See the figure title "Handling Precaution 1" on page 4).

! Do not cover the breathing hole on the top cover (See the figure title "Handling Precaution 2" on

page 4).

! Do not touch the interface connector pins or the surface of the printed circuit board.

! The drive can be damaged by shock or ESD (Electric Static Discharge). Any damages incurred to the

drive after removing it from the shipping package and the ESD protective bag are the responsibility of
the user.

4.5 Performance characteristics

File performance is characterized by the following parameters:

! Command Overhead

! Mechanical Positioning

! Seek Time

! Latency

! Data Transfer Speed

! Buffering Operation (Look ahead/Write Cache)

Note: All the above parameters contribute to file performance. There are other parameters which contri-

bute to the performance of the actual system. This specification defines the essential file characteristics.
This specification does not include the system throughput as this is dependent upon the system and the
application.

The following table gives a typical value for each parameter. Detailed descriptions are found in
Section 5.0.
