Disk speed=3600 rpm Average seek time=30 m secs. Find the disk storage capacity and the data transfer rate. =============== How we can find disk capacity without having sectors and also how to find data transfer rate?

Best answer 2 votes 2 votes Disk Storage capacity= Track Storage * number of tracks = 130030 B * 404 =52532120 Bytes Disk speed = 3600 RPM 1 round in 60/3600 sec so in 1/60 sec ----> 52532120 Bytes can be transferred Data rate = 52532120 * 60 Bytes/sec Dharmendra Lodhi answered Oct 2, 2018 selected Oct 2, 2018 by iarnav Dharmendra Lodhi comment Share Follow See all 12 Comments See all 12 12 Comments reply Show 9 previous comments Dharmendra Lodhi commented Oct 2, 2018 reply Follow Share yes, if question is not saying anything about number of surfaces then assume it as single surface disk 2 votes 2 votes iarnav commented Oct 2, 2018 reply Follow Share Thank you, you guys @Dharmendra Lodhi @ eyeamgj 0 votes 0 votes Roseju commented Dec 3, 2019 reply Follow Share I didn't understand the data rate calculation... can you please explain the fact... 0 votes 0 votes Please log in or register to add a comment.
