When you are choosing a new hard drive, which performance measurement should you evaluate as having the most impact on system performance?
1. >>Average Access Time
2. Latency
3. Average Seek Time
4. Transfer Rate
Explanation : There are a number of things to consider when you are purchasing a hard drive, including size, cost, and performance. There are a number of ways to measure hard drive performance, including Average Seek Time, Average Access Time, Latency, and Transfer Rate.
Average Seek Time (measured in milliseconds) is the amount of time it takes to move the heads from one cylinder to another.
Latency is also measured in milliseconds and is a measurement of the amount of time it takes for the data to be available after the heads reach their destination.
Average Access Time is the sum of the Average Seek Time and Latency.
The most significant performance factor is Transfer Rate. It is a measurement of the rate at which data is sent to the system. This rate depends on the controller as well as the hard drive.
