Microchip Adaptec 8405 RAID Controller 4-Channel 12Gb/s SAS PCIe 3.0 x8 Low Profile

The Microchip Adaptec 8405 is a high-performance RAID controller designed for internal storage connectivity in servers and workstations. Featuring a single SFF-8643 (mini-SAS HD) connector, it provides four internal SAS/SATA ports with data transfer rates up to 12Gb/s per port. The controller supports a wide range of RAID levels including 0, 1, 1E, 5, 6, 10, 50, 60, and JBOD, making it suitable for both performance and redundancy configurations.

Advantages

With 1GB DDR3 1866MHz cache memory and optional Zero-Maintenance Cache Protection (ZMCP) via the AFM-700 flash module, the Adaptec 8405 ensures data integrity and high throughput. The low-profile MD2 form factor fits into standard server chassis, and the PCIe 3.0 x8 host interface delivers ample bandwidth for demanding storage workloads.

Suitable for

• Enterprise servers requiring reliable RAID protection
• Workstations with high-speed internal storage needs
• Data centers deploying SAS or SATA drives
• Applications needing RAID 5/6/10/50/60 for performance and redundancy
