Lenovo DE Series Storage offers several advantages for video surveillance, including modular scalability, lower risk, and simplified management. It is designed to handle write-intensive workloads typical in surveillance, ensuring high performance and reliability. The storage systems also provide over 99.999% availability, making them suitable for critical security applications.

Block storage, like that provided by Lenovo DE Series, offers a more secure and efficient architecture compared to NAS. With block storage, data is accessed directly by the operating system, reducing the risk of unauthorized access. In contrast, NAS systems rely on file systems that can introduce management complexities and security vulnerabilities, making block storage a more reliable choice for surveillance workloads.

Lenovo DE Series Storage employs a modular architecture that allows organizations to start small and scale as needed. It supports a granular, building-block approach to growth, enabling users to add capacity in increments without downtime. This flexibility is crucial for adapting to the increasing demands of video surveillance, such as more cameras and longer retention periods.
