¿Qué medidas se utilizan para evaluar el rendimiento de un sistema de disco?

Which measurements are used to evaluate a disk systems performance?

It depends on the rotational speed of a disk (or spindle motor), measured in revolutions per minute (RPM). For most magnetic media-based drives, the average rotational latency is typically based on the empirical relation that the average latency in milliseconds for such a drive is one-half the rotational period.

3 Answers. Disk speeds are usually measured in; Rotational speed in revolutions per minute (lowest at 4200rpm, then 5400, 7200, 10k and 15k – this isn’t applicable to SSDs or flash memory).

Hardware characteristics, such as disk-storage configuration, can strongly influence the performance of your system. The number of disk operations per second, or the capacity in megabytes transferred per second, has a very strong impact on the performance of the overall system. …

Use Activity Monitor in the Utilities folder to check the status of several variables related to performance. After you launch Activity Monitor, select the “Disk” tab to view information specific to your hard disk. A hard disk performs two basic functions — reading and writing data.

The easiest way to test your hard drive is by using hard drive testing software. These programs are specially designed to check every tiny part of the hard drive for issues and then report anything it finds.

Defragmenting or freeing up space on a computer’s hard drive can improve performance. Computers can be slowed down significantly when too many programs are accessing the network connection at once. Viruses, spyware, and other malware can slow down a computer. Installing additional RAM may help increase computer speed.
