How Many Hours of Video Does a 32GB, 64GB, 128GB or 256GB SD Card Hold?

Quick Shortcut: For 90% of drivers and homeowners, 128GB is the sweet spot: it holds ~16 hours of 1080p dashcam footage (roughly 2 weeks of daily commuting before overwriting) or ~12 days of non-stop 24/7 CCTV footage.

1. Dashcam Recording Times (Nextbase, Garmin, Viofo)

  1. 32GB Card: ~4 hours of 1080p HD (or ~2 hours if you have a Front + Rear dual camera).
  2. 64GB Card: ~8 hours of 1080p HD (or ~4 hours of 4K / Front + Rear dual recording).
  3. 128GB Card (Most Popular): ~16 hours of 1080p HD (or ~8 hours of 4K / Front + Rear). That equals roughly 2 full weeks of normal UK driving before the oldest clips are overwritten.
  4. 256GB Card: ~32 hours of 1080p HD (or ~16 hours of 4K / Front + Rear)—ideal for delivery drivers, taxis, and long road trips.

2. Home Security Camera Recording Times (Tapo, Eufy, Reolink)

  1. 64GB Card: ~6 days of continuous 24/7 recording (or 2 to 3 months if set to 'Motion Events Only').
  2. 128GB Card (Best Value & Max Size for Eufy): ~12 days of continuous 24/7 recording (or 4 to 6 months of motion-triggered clips).
  3. 256GB Card (Tapo & Reolink): ~24 days of continuous 24/7 recording (Note: Eufy cameras cap out at 128GB, so stick to 128GB for Eufy).

3. GoPro, DJI Drones & 4K Action Cameras

  1. 64GB Card: ~2 hours of 4K60 video.
  2. 128GB Card: ~4 hours of 4K60 video.
  3. 256GB Card (Sweet Spot): ~8 hours of high-bitrate 4K60 / 5.3K video—plenty for a full weekend trip without swapping cards.

4. Car USB Music, Sat Navs & Gaming Consoles

  1. 32GB Car USB / Sat Nav Card: Holds 6,000 to 8,000 MP3 songs (~400 hours of music) or full UK & Europe Sat Nav maps, and works plug-and-play because 32GB comes pre-formatted as FAT32.
  2. 256GB Console Card (Switch / Steam Deck): Holds roughly 20 to 30 full-size games.
