Can anyone help me solve this :
Assume that you have a disc-system with 300 256-byte sectors pr. track and assume that the disc rotates with 800 rpm.
How long time does it take to read a sector? The answer should be in microseconds. Search time isnt needed.
Solved it myself. Wasn't really as hard as I thought :)
It reads 800 * 300 sektorer pr. minute.
It reads 24.000/60 sectors pr. second.
It reads 400 sectors pr. second.
To read 1 sector, it uses 1\400 seconds
