Hitachi HUS103073FL3600, HUS103036FL3600, HUS103030FL3800 specifications 1 Vibration test direction

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 1x109 bytes on this document.)

Note 3. Ultrastar 10K300 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.
