Today I am going to calculate the storage space it takes to record someone’s life.
So for the recording of a life’s activity, I took the data I was provided by my mother’s phone – Samsung A7(2016). It records 1080p videos at 30fps. I recorded a 1-minute video and found out it takes 124.7 MB of storage space.
The life expectancy of a person living in India is 68.57 years and in Japan (highest) is 83.98 years.
The oldest person alive right now is 115 years, and the verified oldest person that ever lived on the Earth is 122 years.
To calculate the storage space it would take to contain someone’s life I will first convert the years to minutes by multiplying 525600 to the years because 1 year = 365 days = 8760 hours = 525600 second if there are no leap years. After converting years into seconds we will multiply 124.7 to find how much MB it will take. For converting MB to TB just divide 1000000 (Nowadays 1MB is referred to be 1000 KB, not 1024 KB to make it easy to calculate) because 1 TB = 1000 GB = 1000000 MB. Which means directly multiply 65.54232 to the age to get the results.
So after calculating I found out that if I recorded a person who lived up to the life expectancy, his video’s storage space would be 4494.2368824 TB and 5504.2440336 TB for India and Japan respectively. The oldest person alive will be taking 7537.3668 TB as of now and the oldest person that ever lived will be taking 7996.16304 TB.
To understand this I will divide the result by 60 to represent the number of 60TB hard drives (currently the largest) it will take to store the data.
So the person who lived up to the life expectancy will fill up 75 and 92 hard drives for India and Japan respectively. The oldest person alive will fill up 126 hard drives as of now and the oldest person that ever lived will fill up 134 hard drives.
