Dumas, who has excellent mechanical aptitude, owns a computer with two hard drives. One drive is used for the operating system and the other drive is used for his personal files. He decides to install a third disk in a RAID 1 configuration to protect the disk with his files against data loss. He is not too concerned about data loss on the disk with the operating system because he could easily reinstall the OS, so that disk is not included in the RAID configuration. When he is done, he powers up his computer, no error messages are displayed, yet he is distraught because all his data is lost. Why would this happen? Since the new drive had no data, and RAID 1 mirrors data, it erased the data on the original. He didn't back up his data. When RAID is configured all data on participating drives is lost. The new drive was smaller than the original drive so the data from the original did not fit. The RAID expansion card is not seated properly so the RAID drives are not being detected.
He didn't back up his data. When RAID is configured all data on participating drives is lost.

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? The new drive was not detected so the system continues to use RAID 5, but in a degraded mode. You can't rationalize this behavior. It is a false statement. Performance should not be degraded. It takes time to rebuild the data on the new drive. During this time performance is degraded. When a RAID 5 drive fails, the data is temporarily written to pagefile.sys which is slower than RAID 5.
