Consider a spinning hdd with a random access time of 90ms and an effective transfer rate of 60mb/s. now consider an ssd with a random access time of 100μs and an effective transfer rate of 500mb/s. assume all files are contiguous and that seeks within otherwise contiguous reads take negligible time.
(a) what will the speedup of the ssd over the hdd be when reading 5,000 files totaling 140mb? (amdahl’s law will not you here, but you have enough information to determine the answer without it.)
(b) what will the speedup of the ssd over the hdd be when reading 130 files totaling 1gb? (amdahl’s law will not you here, but you have enough information to determine the answer without it.)
