Lenovo RAID 940-16I 8GB Flash Internal PCIe 4.0 x8 | SAS RAID

Keep internal server storage responsive with the Lenovo RAID 940-16I 8GB Flash Internal controller. Built on PCIe 4.0 and designed for 12 Gb/s SAS connectivity, it gives server teams the bandwidth and cache architecture needed to support dense drive configurations and sustained transactional workloads. The 8 GB flash-backed cache is the differentiator. It helps preserve write data during unexpected power events, which matters when the controller sits at the center of application storage, virtualization, or database workloads. RAID support spans the common protection tiers used in enterprise servers, including 0, 1, 10, 5, 50, 6, and 60, giving architects flexibility to balance capacity, performance, and fault tolerance. This controller is a practical choice when uptime and recovery behavior matter more than entry-level pricing. It is designed for internal server deployment, integrates cleanly into supported ThinkSystem platforms, and carries a 1-year limited warranty. For infrastructure teams standardizing on Lenovo server components, it offers the performance headroom and data protection expected from a premium RAID adapter.
