Description
SanDisk 256GB microSDXC Memory Card
Memory card presented in the source for dash cameras and home-surveillance systems, with an emphasis on endurance. The listing claims up to 20,000 hours of video recording; it specifies Full HD (1920 × 1080) only and says total recording time is lower for 4K UHD (3840 × 2160).
Specifications stated in the listing
- Brand: SanDisk
- Capacity: 256GB (the source defines 1GB as 1,000,000,000 bytes; usable storage is lower)
- Format: microSDXC
- Speed class: Class 10
- Read speed: up to 100MB/s, as listed
- Write speed: varies
- Dimensions: 15 × 11 × 1 mm
- Video support: Full HD or 4K only with a compatible host device; performance and recording time vary by device, file attributes and operating conditions
The source claims resistance to temperature, water, shock, humidity and magnets, for the card only. It does not specify protection ratings or limits; check the package and the exact SanDisk model details before relying on those claims.
The listing says Class 10 guarantees at least 10MB/s. SD Speed Class specifies a minimum sequential performance under defined conditions; actual transfer speed depends on the card, reader and host. Although the source lists compatibility with microSDXC and microSDHC hosts, a 256GB card requires a host that supports microSDXC. Confirm device capacity and format support before use.
