Just picked up a used DS920+ to move from my DAS. It will be used for Plex Server and library storage, using SABnzbd or NZBGet incorporating SONARR and RADARR. Should I invest in M2 cards for cache or pooling to increase download efficiency and speed, I am on a 1Gbps line.
Or should I invest that money in larger capacity HDD? I have RAM in hand to install once I receive the unit. Thanks for the help.

If you’re using the DS920+ primarily for Plex and download management with Sonarr, Radarr, and SABnzbd/NZBGet, investing in M.2 NVMe SSDs for caching can improve efficiency, especially if you’re handling high-traffic media libraries or doing frequent, large downloads. However, since you’re on a 1Gbps connection, the cache may have limited impact on download speed itself—it’s more useful for reducing latency in accessing frequently used data.
If your media library is large and growing, you might see better overall performance from putting the budget toward larger capacity HDDs. With the additional RAM, you’re already setting up for improved multitasking performance, which should help with download processing. In short, if storage space is tight or expected to grow quickly, larger HDDs would likely be the better investment.
