, Question 1
a. Given that the hard drive has 100GB of data stored,
100GB = 100 000MB
100 000MB / 200MB/s = 500s
500s/ 60 = 8.33
It will take 8.3 minutes to write 100GB of data.
b. When a file is deleted in the recycling bin, or if one right clicks on the
recycling bin and chooses the option to empty recycling bin, then the
file is permanently deleted and is not recoverable.
c. SSDs contains a storage cell with limited life expectancy. Each time
new data is added, the old must be deleted and with time this wears
down the cells and according to Moukine (2018), it only takes a small
percentage of bad sectors for data loss to occur. As SSD use flash
memory there is no physical location for data to be stored.
In contrast, a HDD stores data on spinning disks thus making it
relatively easier to recover data from a physical drive.
