The notion of âtransformative constitutionalismâ has found a deep resonance in the jurisprudence of the courts, academic literature and civil society campaigns for social justice.
If you simply write data to a USB flash drive and put it away in a safe place for 10 years, it will work again and all the data will still be there. But if you continue to use it over and over again, it will definitely wear out eventually. USB Flash Drives Have Finite Number of Write/Erase Cycles. The life expectancy of a USB Flash Drive can be measured by the number of write or erase cycles. USB flash drives can withstand between 10,000 to 100,000 write/erase cycles, depending on the memory technology used.
The difference between real-wold reliability and MTTF ratings is down to how MTTF is worked out. Obviously, when a drive has a MTTF rating of 1,000,000 hours (around 114 years) no manufacturer has actually invested that amount of time in testing a series of drives to see if they last that long. In fact, MTTF has nothing to do with how long a single drive, or series of drives, is expected to last. MTTF is a statistical trick that can be adequately summarized by the formula below: ([a short time period] * [number of items tested]) / [number of items tested which failed within time period] = MTTF.
