Current State

• Multiple devices: SD cards, flash drives, SSD (T7 Shield), HDD (plugged into Pi4)
• SSD (T7 Shield): NOT plugged into Pi4 — intentionally separated due to power interference
• HDD: The one plugged into Pi4 — ~4TB total, realistically ~3.6-3.8TB
• No unified architecture for organization, backups, how they work together
• SSD is nearly full (~2TB), messy organization, duplicates across SSD and HDD
• Critical finding: HDD controller issues appeared ONLY when SSD was plugged in simultaneously — confirmed interference pattern
• Thrust: theorize → design → verify
• At least 10+ SD cards and flash drives total
