In this part of the video, the content creator discusses installing SSDs on a Synology DS918+ NAS. They explain navigating the interface to set up SSD cache but encounter an issue due to a bug when having 16GB of RAM installed. The video then proceeds to show the process of shutting down the NAS and preparing to swap out the drives with Samsung M.2 NVMe SSDs, specifically the 960 Evo. The content creator provides affiliate links for the SSDs on Amazon to support their channel.

In this segment of the video, the speaker installs dual SSDs and explains how caching works. They show the process of inserting the chips, mention read and write caching functionalities, and complete the setup. Then, the speaker performs speed tests before setting up the cache. They copy files to the server and measure transfer times. Afterward, they explain that they will set up the cache through the DiskStation manager and proceed to do so.

In this segment of the video, the speaker creates a read-write cache using two SSDs in RAID1 (mirroring) for improved speed and performance. They mention enabling sequential I/O for backup applications and skipping it for streaming purposes to preserve SSD lifespan. The SSD cache is created successfully, and the speaker highlights that the SSDs can only be used for caching in this NAS setup, not for creating a volume. They run tests to show improved write and read speeds after implementing the SSD cache.

In this segment of the video, the speaker discusses testing the cache speed on a system, with varied results. They observed both faster and slower speeds after caching was implemented, making it challenging to determine its impact. The speaker mentions running virtual machines on the Disk Station could utilize the SSD cache significantly. Overall, the simple file tests did not show a substantial speed improvement with caching, but further testing and real-world usage may provide clearer insights.
