¹ Speed may vary for devices that do not support UHS-I due to different interface requirements. ² The 512, 256, 128 and 64 GB SD memory cards support 4K UHD video recording. Compatibility may vary depending on the host device. ³ The read and write speeds quoted are based on internal tests carried out under controlled conditions. Actual speeds may vary depending on card capacity. The stated performance was achieved by using PRO Ultimate SD memory cards with Samsung readers.
⁵ 1 GB = 1,000,000,000 bytes. Some capacity may be used for system files and maintenance, so actual capacity may vary. ⁵ Test device: Sony Alpha 1.
⁶ 4K video (3,840 x 2,160 pixels), 30 fps, 60 Mbit/s (Average file size for 30-minute recordings: 13.8 GB). ⁷ FHD video (1,920 x 1,080 pixels), 30 fps, 16 Mbit/s (Average file size for 30-minute recordings: 5.2 GB). ⁸ 4K photo 3,840 x 2,880 pixels (Average image size: 5.5 MB). ⁹ FHD photo 2,880 x 2,880 pixels (Average image size: 4.3 MB).
¹⁰ The 7-fold protection applies to the SD memory card and not to the separately available USB card reader. Samsung is not liable for any damage and/or loss of data or costs incurred in recovering data from a memory card. ¹¹ The commitment of the separately available USB card reader is limited to one year. ¹² Waterproof: up to 72 hours in 2 metre deep seawater. ¹³ Temperature resistant: Operating temperatures from -25°C to 85°C, not in use: from -40°C to 85°C. ¹⁴ X-ray safe: up to 100 mGy (equivalent to X-ray scanners at airports). ¹⁵ Magnet-resistant: up to 15,000 Gauss (corresponds to the magnetic field of a high-field MRI). ¹⁶ Shockproof: shocks up to 1,500g (g = gravitational acceleration) ¹⁷ Drop-proof: withstands drops from up to 5 metres. ¹⁸ Wear-resistant: up to 10,000 mating cycles.
¹⁹ The UHS Class 3 standard refers to a performance option designed for 4K UHD video recording with UHS-compatible host devices. According to Video Speed Class 30 (V30), a continuous video recording rate of 30 MB/s must be achievable. The performance option enables real-time video recording with UHS-enabled host devices.
