Pricing Logic

The tool automatically suggests prices based on:

• Capacity (larger = higher price)
• RPM (7200 RPM = premium over 5400 RPM)
• Form factor (3.5" desktop vs 2.5" laptop)
• Brand/Model (WD Green = energy efficient pricing)
• Usage hours (affects condition rating)

Price Ranges

• 1TB 7200 RPM: $25-30
• 1TB 5400 RPM: $20-25
• 750GB 7200 RPM (2.5"): $20-25
• 500GB-750GB: $15-20
• 250GB: $10-15

Safety Features
