A client has a workstation with a RAID 5 configuration and reports that slower than normal performance occurs when reading/writing files to the RAID. You run a diagnostic program against the RAID, and the system passes all of the diagnostic tests without any issues. While you are running the tests, though, you heard clicking noises coming from the RAID. Which of the following is the MOST likely cause of the slow performance being experienced by the client? A.RAID controller B.SSD C.Cooling fan D.Hard drive
D. Hard drive Based on the symptoms described, the RAID itself is fully functional, so the RAID controller is not causing any problems. This could be caused by a failing hard drive or the system overheating due to the slow performance. Since there is a clicking noise, this is most likely a hard drive failure since a cooling fan makes a whirring or grinding noise instead. Therefore, we can assume the RAID is made up of magnetic hard drives, and one of those hard disks is starting to fail
