Tell Us About Your Configuration! Which NAS and Drives?

As this community is just starting, I thought learning more about each other's setups would be interesting.

I'll go first:

• DS916
• 4x8TB Hard Drives: 3 WD Reds, 1 Seagate Ironwolf (oldest drive is 53,150 hours or just over 6 years)

I haven't had to replace anything yet (knock on wood)!
