Virtual memory is a software-based memory management system that allows a computer to use hard disk storage space as RAM. This can be used to increase the total RAM in a system without upgrading the hardware. To set up virtual memory, the user should go to the System Properties window and select the Advanced tab. In the Performance section, click on the Settings button, which will open the Performance Options window. Then, click on the Advanced tab and click on the Change button in the Virtual memory section. Finally, select the option to Automatically manage paging file size for all drives, and then click OK to save the changes.

A non-volatile memory express (NVMe) solid state drive (SSD) is the best option for an end user who wants to upgrade the hard drive on a laptop and wants one that is fast and shock resistant.NVMe SSDs use flash memory and PCIe interface to achieve high performance and low latency.SSDs are also more shock resistant than hard disk drives (HDDs) because they have no moving parts.Hybrid HDD/SSD combines both technologies but does not offer the same speed or capacity as pure SSDs.A 5,400rpm HDD or a 7,200rpm HDD are slower and less shock resistant than SSDs

Since the RAID card does not support hot swapping, the technician needs to shut down the server and check the RAID controller’s status to verify RAID health. S.M.A.R.T. is a feature of hard drives, not RAID cards. Replacing the failed drive while users are connected could cause data loss or corruption. Physically cleaning the HDDs and connectors is unlikely to solve the slow boot time and performance issues. 

TPM stands for Trusted Platform Module, which is a hardware component that securely stores encryption keys and other sensitive data12. TPM can be used to enable hard drive encryption, which is a technology that encrypts the data stored on a hard drive using sophisticated mathematical functions34. Hard drive encryption protects the data from unauthorized access in case the hard drive is lost, stolen, or tampered with.
