This is the Kingston SDCS2/512GB Canvas Select Plus microSDXC memory card, an earlier generation of Kingston's mainstream Canvas Select Plus line rated UHS-I U1 (not the newer U3-rated SDCS3 revision also sold in this catalogue), delivering read/write speeds of 100MB/s and 85MB/s respectively — solid everyday performance for HD video recording, photo storage and general file transfer rather than professional-grade 4K capture. It's designed to survive water, extreme temperature, shock, vibration and X-ray exposure, carries CPRM support, and ships with a full-size SD adapter so it works in any standard SD card slot as well as microSD-native devices like phones and cameras. It is not compatible with SDHC-only cameras or readers, since it's a full SDXC-format card. At 512GB it offers substantial capacity for a phone, tablet or dashcam, and Kingston covers it with a lifetime warranty.
