Note 1. Storage capacity does not include spare sector and spare cylinder.
Note 2. This is the value in the case that the drive is formatted to 512 Bytes/sector.
(1 gigabyte shows 1x10
9
bytes on this document.)
Note 3. Ultrastar 15K73 is formatted to 512 Bytes/sector as the default.
If non-512 Bytes/sector is required, customer can change it by re-format
of the drive.
Note 4. Data transfer rate is degraded with cable or host condition or electrical noise.
Note 5. These specifications are typical under the following conditions:
1. Voltage is 5.0V/12.0V as measured on the edge of drive connector.
2. Surface temperature of HDA is 40
°C
.
If SCSI commands are issued during start-up (like TEST UNIT READY or
REQUEST SENSE) in less than 10 ms intervals, then the start-up time may be
extended.
Note 6. The disk drive orientation for vibration test is shown below.
Figure 3.1 Vibration test direction
Test conditions on vibration test are as follows.
(1) Operating
Acceleration frequency : 5 to 400 Hz,
Acceleration level : 9.8m/s2(1.0G)
Sweep rate : 0.5 octave / minute
Test cycle : 1 turn
(2) Non-operating
Acceleration frequency: 5 to 22 Hz, Maximum displacement: 2.56mm
Acceleration frequency: 22 to 400 Hz, Acceleration level: 49m/s2(5.0G)
Sweep rate: 0.5 octave / minute
Test cycle: 1 turn
