CmpE130 Fall 2009 HW2 1 of 1 CmpE130 Homework 2 Due date : 10 Sept. 2009 Examine the specifications for the Samsung HD103UJ found at http://www.samsung.com/global/business/hdd/productmodel.do?grou (click on the “specifications” tab). 1.

Unformatted text preview: 3. Using the manufacturer's specified average seek time and latency, and assuming the average value for sectors per track, estimate the time required to write a file of size 960 megabytes (1 MB = 2 20 B), stored in clusters of 16 sectors, located randomly on the disk. 4. Repeat the previous calculation, assuming that the file is stored in adjacent cylinders. Note the proposal to provide new binary prefixes that would alleviate the confusion caused by having two different ways of calculating gigabytes (10 9 or 2 30 ): http://en.wikipedia.org/wiki/Binary_prefix#IEC_standard_prefixes ....
