This WD Purple SC (QD101) microSD card (1TB) is designed specifically for the mainstream security camera market, built to handle the 24/7 continuous recording workload of an always-on surveillance system. It uses 96-layer 3D NAND for a cost-effective combination of ultra endurance and consistent performance, and includes card health monitor functionality that enables pre-emptive storage management before a card wears out. It's engineered to keep up with the fast-growing demands of security cameras and the increasing adoption of 4K video at the edge. Purpose-built as surveillance storage rather than a general-purpose memory card. Model WDD100T1P0C is sold as shown above.
