Average and minimum times for reading and writing to st

    Average and minimum times for reading and writing to storage devices are common measurements used to compare devices. Using techniques from Chapter 8 calculate values related to read and write times for disks with the following characteristics.
    Av. Seek Time
    RPM
    Disk Transfer Rate
    Controller Transfer Rate
    a.
    11 ms
    7200
    34 MBytes/s
    480 MBits/s
    b.
    9 ms
    7200
    30 Mbytes/s
    500 MBits/s
    (a) Calculate the average time to read or write a 1024-byte sector for each disk listed in the table above.
    (b) Calculate the minimum time to read or write a 2048-byte sector for each disk listed in the table.
    (c) For each disk in the table determine the dominant factor for performance. Specifically if you could make an improvement to any aspect of the disk what would you choose? If there is no dominant factor explain why.
