Volume Estimation Formula

Daily Volume (GB) = EPS * Average Event Size (bytes) * 86400 / 1,073,741,824

Example:
  EPS = 100
  Avg Event Size = 500 bytes
  Daily Volume = 100 * 500 * 86400 / 1,073,741,824 = 4.03 GB/day
  Monthly Volume = 4.03 * 30 = 120.9 GB/month

Cost-Value Assessment Matrix

Security Value	Low Volume (<1GB/day)	Medium (1-10GB)	High (>10GB)
Critical	Must have	Must have	Evaluate ROI
High	Should have	Should have	Evaluate ROI
Medium	Nice to have	Evaluate ROI	Defer
Low	Defer	Defer	Reject
