Lenovo ThinkSystem RAID 930-4i-2GB 4-Drive Adapter Kit | RAID 5/6, PCIe

Protect server workloads with hardware RAID built for sustained uptime and predictable storage performance. The Lenovo ThinkSystem RAID 930-4i-2GB 4-Drive Adapter Kit for SN850 adds a dedicated RAID controller with 2 GB of cache, giving you the write buffering and parity handling needed to keep transactional systems responsive under load. Designed for Lenovo ThinkSystem environments, this adapter supports four drives and is suited to deployments where storage resilience matters more than basic pass-through connectivity. Hardware RAID offloads parity calculations from the host CPU, helping preserve system resources for applications, virtualization, and database activity. That matters when you are consolidating workloads or protecting data on a server that cannot afford avoidable I/O bottlenecks. Compared with entry-level controller options, this kit is built for administrators who need stronger fault tolerance, better cache behavior, and a cleaner path to RAID-based protection. It is a practical choice for teams standardizing on Lenovo infrastructure and looking to add dependable RAID capability without overbuying capacity they will not use.
