The Fujitsu PSAS CP400i is a host bus adapter designed to manage internal SAS and SATA hard drives and SSDs within a server environment. Built around the LSI MegaRAID SAS3008 chipset, it utilizes a PCI-Express 3.0 interface to provide a fast transfer rate of 12Gb/s, ensuring that data moves efficiently between your storage devices and the system. This 8-port adapter supports RAID 0 and 1 configurations, allowing you to choose between increasing read speeds or creating a mirrored backup for better data reliability. Because it operates without a dedicated cache, it offers a straightforward hardware implementation for those who need reliable connectivity for multiple drives without the complexity of cached memory management.
