Your computer has three drives in a RAID 5 configuration. One of the drives fails so you replace it right away. Immediately upon replacing the drive you notice that the overall performance seems to have been degraded. You research the issue and conclude that this is the expected behavior. How can you rationalize this behavior?
It takes time to rebuild the data on the new drive. During this time performance is degraded.
Johan is a hard drive performance engineer working at a major storage device manufacturer. He needs to measure, record, and analyze the throughput, IOPS, and the latency of the different models of drives the company produces. What is the difference between these three parameters? Select three.
Latency measures the time required to process a data request or a transaction. IOPS is the amount of data flow through a point in the data path in one second. Throughput is the amount of data flow through a point in the data path in one second.
