🚀 What You Should Consider:

Drive Brands & Capacities: You're already using a mix of Seagate IronWolf and Western Digital Red drives, which are reliable for NAS environments. For further expansion, sticking to these drive series is recommended for compatibility and performance.
SSD Caching: Your existing Sabrent SSDs are a great addition for cache purposes, which will significantly boost performance, especially with frequent file access.
Expansion with DX517: The 5-bay DX517 expansion allows you to use those additional 8TB Seagate drives, giving you substantial room for growth.
