Difference between Rotational Latency and Disk Access …

WebSuppose we have a computer with the following characteristics: the level-2 cache has an access latency of 8 nanoseconds and a streaming transfer rate of 800 megabytes per second, the main memory has an access latency of 60 nanoseconds and a streaming transfer rate of 80 megabytes per second, the hard disk has an access latency of 15 mil- … Webaverage, the rotational latency is half the time it takes the disk to make a complete revolution. The disk spins at 10000 RPM, so it takes 1/10000 of a minute to make one revolution. Equivalently, (1000 ms/sec × 60 sec/minute) / 10000 RPM = 6 ms to make one revolution. So rotational latency is 3ms. coinmarketcap clv https://milton-around-the-world.com
