   A customer's laptop is making clicking sounds in the area where non-volatile storage is installed. A technician examines the laptop and confirms the issue. Which of the following is the most appropriate replacement part?

   • A7,200rpm HDD
   • BNVMe SSD
   • CM.2 SATA SSD
   • DSCSI 15,000rpm HDD

   Show answer

   Answer: B

   Explanation

   B. NVMe SSD is the most appropriate replacement part. NVMe SSDs (Non-Volatile Memory Express Solid State Drives) are known for their high performance and reliability. They offer significantly faster read and write speeds compared to traditional HDDs and SATA SSDs, which can help to alleviate the clicking noise and improve overall system performance. Here's why the other options are less suitable: A. 7,200rpm HDD: While HDDs are more affordable, they are slower and more prone to mechanical failures, which can lead to clicking noises. C. M.2 SATA SSD: While M.2 SSDs are faster than traditional HDDs, they are still limited by the SATA interface. NVMe SSDs offer significantly better performance. D. SCSI 15,000rpm HDD: SCSI drives are high-performance drives, but they are more expensive and less common than NVMe SSDs. They are also prone to mechanical failures. By replacing the failing drive with an NVMe SSD, the technician can improve the laptop's performance and reliability. GG

   It is C and D. You need enough Wattage and be sure that the PSU will fit in the machine. Many pre-made computers have different size PSUs Efficiency doesn't matter, a gold rated will work as well as a platinum, the latter just being better. Heat has nothing to do with the question Fan doesn't either Modular cabling is never required, it's just nicer.
