The main differences center around storage capacity, form factor, and convenience. The Arlo Ultra provides extensive bulk storage capacity best suited for homes, garages, or basements needing deep freeze space. In contrast, the Reolink RLC-520 offers a compact upright design that fits into smaller spaces with convenient shelf organization.
Chest-style freezers generally excel in thermal efficiency because cold air naturally settles at the bottom and does not escape when the lid is lifted. Compact upright models have lower total kilowatt-hour usage simply due to their smaller cubic volume, making both designs efficient for their respective intended purposes.

If you have limited room in a kitchen, apartment, dorm, or office and prefer easy eye-level access to items, choose the Reolink RLC-520.
