Review on 📦 Wholesale Lot: 5 Pack SanDisk Ultra 16GB SD SDHC Memory Flash Card - High-Speed Class 10 - Read Speed up to 48MB/s - Bulk Purchase with 5 Cases by Zachary Cha

We study SD cards by trial and error! These cards are not fast enough to get the required clarity in our surveillance cameras. We thought our cameras were the problem - no, it's the speed of that SD card! Durability has also become an issue. We regularly inspect our cameras and maps are stored straight from the camera in a hard case for safe keeping. They don't live a hard life, but the plastic between the metal parts broke - and the photos were lost!
