Computer Sciences > GATE 2015 SET-2 > Disk I/O
Consider a typical disk that rotates at 15000 rotations per minute (RPM) and has a transfer rate of 50 x 106 bytes/sec. If the average seek time of the disk is twice the average rotational delay and the controller's transfer time is 10 times the disk transfer time, the average time (in milliseconds) to read or write a 512-byte sector of the disk is _______.
Correct : 6.1 to 6.2
