Question 1

Which of the storage technologies we have discussed in this course is most suitable for each of the following applications (explain each choice):

-Data archival (the long-term storage of data).

-Searching a large, regularly structured, database index.

-Serving digital movie files to the projectors in a ten-screen theatre.

Question 2

Approximately how many times can FLASH memory be safely overwritten? Why is there a limit, and how can we lengthen the useful life of such memories? (Please be sure to cite any external sources on which you depend in your answer)

Question 3

You are conducting a scientific experiment that generates a Petabyte of data in under a second. Both you and the world will need access to the data soon after, but you can wait at least 24 hours if you wish (i.e., you only generate a Petabyte no more often than once every 24 hours, but it is generated in a single second). How would you imagine a storage system to record such data would look? (describe what technologies and techniques might be used).

Question 4

 You are sold a hard drive, but the seller refuses to tell you what technology is being used in the drive. You suspect it's either a regular magnetic drive, an SSD, an SMR drive, or a hybrid of FLASH and magnetic storage. How would you propose to find out which technology is being used? Describe your approach and the reasoning behind it
