A QNAP TVS-h874T is a Network Attached Storage device.
There are 2 simple fixes that can improve the read and write speed of a NAS, and we will cover both of these in this project.
The first improvement is to upgrade it from 16GB or 32GB of RAM to the maximum of 64GB of RAM. This improves the speed of reads and writes by giving the system more memory for caching data.
The second improvement is to had Solid State Disks also known as SSDs. The QNAP TVS-h874T has 2 internal M.2 SSD slots that can be used to add fast read and write caching. The SSDs allow the QNAP to store data that is in demand on the high speed SSD instead of reading from the much slower hard drives that are installed.
This guide will show how to upgrade the RAM and install M.2 SSDs to increase the speed.
Make sure you safely shutdown your QNAP and mark disconnect all cables before attempting this repair.
