Task 2. Assume that a hard disk drive has 3 double-sided platters. There are 100000 tracks on each recording surface. The disk uses ZBR with two zones: there are 2000 sectors on tracks 1-50000 (zone 1) and 1000 sectors on tracks 50001-100000 (zone 2). The size of the sectors is 500 byte. The speed of the interface of the HDD is 250 - 10 byte/s. The command processing time is 1 ms. The average seek time is 5 ms, the rotation speed is 6000 RPM. is the total capacity of the HDD in bytes? (b) What is the revolution time of the discs? c) Compute the service time of a read request of a single sector, if the sector falls onto track 25000 (zone 1). (d) Compute the service time of a read request of a single sector, if the sector falls onto track 75000 (zone 2) (e) On which zone would you put your frequently used data? Task 2.
