Question

Which parameters are used to evaluate the performance of common storage devices?

Answer 1

Answer:

The most basic metric for I/O performance is throughput. Throughput is a measure of speed—the rate at which the storage system delivers data. Throughput is measured in two ways: I/O rate, measured in accesses/second, and data rate, measured in bytes/second or megabytes/second (MB/s).

Throughput

Throughput parameters are used to evaluate the performance of common storage devices.

• All environments share three essential storage performance metrics: latency, throughput (or bandwidth), and IOPS.
• Measuring disc throughput in megabytes per second (MBps), the most fundamental storage benchmark. Performance of data movement is governed by the read and write speeds of the source and destination, as well as the buffers and buses in between.
• A storage device's performance, particularly its hard drive performance, is measured. This is assessed by running tests on the drive and contrasting the results with benchmark measures.
• Disk throughput is a unit of measurement for the speed at which your storage system can read and write data. If you've ever looked at a new hard drive (HDD) or solid-state disc, you may have seen this number before (SSD). Usually, this is expressed in MB/s, or megabytes per second.
