Thanks for your question — great setup with those Samsung drives and the AS6806T!
Since you’re already running a RAID 5 volume made up entirely of high-performance Samsung 7.6TB SSDs, the benefit of adding an M.2 SSD cache will be minimal or even negligible. Cache is designed to speed up access on slower HDD pools by storing frequently accessed data on faster media. But in your case, your main storage is already ultra-fast SSDs, so caching won’t improve performance much.
Instead, creating a separate volume using your M.2 SSDs is generally the better approach. You could use that volume for workloads that demand ultra-low latency or heavy random I/O — like VM storage, database files, or very active project folders. This lets you leverage the blazing speed of the 990 Pros directly, without any caching layer in between.
Also, aggregating the two 10G ports is a good move to maximize network throughput, ensuring you get the best possible performance across your network.
