	≥ 60% confidence level.
Data Reliability
< 1 per 1014 bits read	Data errors (non-recoverable). Average data error rate allowed with all
	error recovery features activated.
Component Design Life
5 years (minimum)	Component design life is defined as a.) the time period before
	identified wear-out mechanisms impact the failure rate, or b.) the time
	period up to the wear-out point when useful component life expires.
