Problem 1: Samsung recently announced its 990 Pro series of solid state drives (SSD) using a PCle 4.0 interface. They claim sequential read and write speeds of up to 7,450 MB/s and 6,900 MB/s respectively and random read and write speeds of up to 1,400K and 1,550K 1/0 operations/second. It is expected to go on sale in October 2022 at a price of $179 for the 1TB model. Note that capacity is expressed in SI units.
How does the cost per GB of the 1TB Samsung 990 Pro SSD compare with the cost per GB of the 16 TB EasyStore HDD?
Problem 2: Instead of cost/GB, compute the cost/bandwidth (as $/MB/s) for a Seagate 1 TB Barracuda HDD with a maximum sustained data rate of 140 MB/s and the Samsung 990 Pro SSD. Use sequential read speeds for comparison.
Problem 3: An Oregon State University student mistakenly computed the capacity of a 16 TB HDD assuming IEC units instead of SI students. By what percentage was their result in error? Round to the nearest integer percentage.
