Students have asked these similar questions
You have a disk with an average seek time of 3ms. Its rotation speed is 20,000rpm. The disk is organized as 512-byte sectors with 500 sectors per track. Assume that the disk uses sequential organization.
How long would it take to read a file consisting of 3000 sectors?
What is the total size of the file read in MB?
Calculate how much disk space (in whole sectors and tracks) will be required to store 1GB (230 bytes) of data if a disk is single-zoned with 512 bytes/sector and 1024 sectors/track. Ignore any file header record(s) and track indices.
What is the average time to read or
write a 512-byte sector for a typical disk
rotating at 15,000 RPM? The advertised
average seek time is 4 ms, the transfer
rate is 100 MB/sec, and the controller
overhead is 0.2 ms. Assume that the disk
is idle so that there is no waiting time.

- In Feynman's lecture he wondered "why cannot we write the entire 24 volumes of the Encyclopedia Brittanica on the head of a pin". For a modern hard disk drive the area of a single bit of information on the surface of the disk is roughly 10 x 40 nm² in area. In such a hard drive would the area required to store the data for 24 volumes of the Encyclopedia Brittanica be greater or less than the head of a pin? In Feynman's lecture he estimates the 24 million books as big as the Encyclopedia Brittanica has 10¹5 bits of information.arrow_forwardCalculate the access time for a disk having the size of 512 byte/sector and the seek time of 12ms.
