NOTE:
1) Performance measured using CDM 5.0.2 on Windows 10 64bit. Actual performance may vary depending on use conditions and environment.
2) Sequential performance measured using 128KB data size. (QD=32 by Thread=1)
3) Random performance measured using 4KB data size. (QD=32 by Thread 4, QD=1 by Thread 1)
4) Performance measurements based on TurboWrite technology |

2) Idle Power is measured on Idle status with L1.2+APST/ASPM on.
3) If L1.2 time logging option is enabled, L1.2 Power could be 5mW.
4) Active/Idle/L1.2 Power are measured up to 1TB. |
MTBF
MTBF is Mean Time Between Failure, and is the predicted elapsed time between inherent failures of a system during operation. As same word,
AFR (annual failure ratio) is 0.4%. MTBF can be calculated as the arithmetic average time between failures of a system. |
