Lenovo RAID 940-16I 4GB FLASH RAID Controller | Enterprise, Rack Mount

Protect critical workloads with a RAID controller designed for dense server storage and fast recovery after a drive event. The Lenovo RAID 940-16I 4GB FLASH gives infrastructure teams the cache and controller architecture needed to keep arrays responsive while preserving data integrity under pressure. Flash-backed cache matters when write performance and recovery behavior cannot be left to chance. It helps maintain controller state during unexpected power loss, reducing the risk of data loss and extending the value of the storage subsystem beyond basic RAID protection. With support for multiple RAID levels, this controller fits environments that need a balance of performance, redundancy, and capacity efficiency. The 16-port design is well suited to servers that need to attach a larger number of drives without adding complexity. That makes it a practical choice for storage-heavy deployments where controller density, predictable behavior, and serviceability are worth paying for. For teams standardizing on Lenovo infrastructure, this card provides a focused path to stronger storage resilience without overbuying features they will not use.
