4.4 Mean Time Between Failures (MTBF)

Mean Time Between Failures (MTBF) is predicted based on reliability data for the individual

components in PV910-M280. The prediction result for PV910-M280 is more than 3,000,000 hours.

Note: The MTBF is predicated and calculated based on

“Telcordia Technologies Special Report, SR-

332, Issue 3

” method.

4.5 Certification and Compliance

PV910-M280 complies with the following standards:



FCC



CE



RoHS



MIL-STD-810G

4.6 Endurance

The endurance of a storage device is predicted by Drive Writes Per Day based on several factors

related to usage, such as the amount of data written into the drive, block management conditions, and

daily workload for the drive. Thus, key factors, such as Write Amplifications and the number of P/E

cycles, can influence the lifespan of the drive.
