(2)Mean Time to Repair (MTTR)

MTTR is the average time taken by a well-trained service mechanic to diagnose and repair a drive malfunction. The drive is designed for a MTTR of 30 minutes or less.

(3)Service life

The service life under suitable conditions and treatment is as follows.

The service life is depending on the environment temperature. Therefore, the user must design the system cabinet so that the average DE surface temperature is as low as possible.

DE surface temperature: 40°C or less

5 years

DE surface temperature: 41°C to 45°C

4.5 years

DE surface temperature: 46°C to 50°C

4 years

DE surface temperature: 51°C to 55°C

3.5 years

DE surface temperature: 56°C to 60°C

3 years

DE surface temperature: Exceeding 60°C

Without warranty

 

 

(Keep the DE surface temperature 60°C or less)

Even if the HDD is used intermittently, the longest service life is 5 years.

Note:

The "average DE surface temperature" means the average temperature at the DE surface throughout the year when the HDD is operating.

(4)Data security at power failure

Integrity of the data on the disk is guaranteed against all forms of DC power failure except on blocks where a write operation is being performed. The above does not applied to formatting disks or assigning alternate blocks.
