The Series 6 family of high-performance Adaptec Unified Serial® (SATA/SAS) RAID controllers offers maximum performance, scalability and reliability. With the enhanced bandwidth of its 6 Gb/s SAS2.0 interfaces and the PCIe Gen2 host connection it offers up to 60% higher sustained sequential throughput than previous generation controllers.

Based on PMC-Sierra''s market-leading, multi-core SRC 8x6G RAID-on-Chip (RoC) the Adaptec RAID 6805 can deliver up to 2 GB/s sustained data transfer rate to the host. Peak performance is up to 4.8GB/s through the SAS 2.0 interfaces and 4.0GB/s through the PCIe Gen2 host interface. Using SAS expanders, it can connect up to 256 SATA/SAS.

The Adaptec RAID 6805 supports a broad range of operating systems, compatibility with more than 300 third-party devices, and full integration with Adaptec Storage Manager™ for centralized management of all Adaptec RAID controllers on the network.

Zero-Maintenance Cache Protection Kit Option – Maximum protection and Savings
Adaptec Series-6 is the industry''s first Unified Serial RAID controller which offers Zero-Maintenance Cache Protection that eliminates Battery backup Units ( BBUs) in favor of 4GB of NAND flash memory to protect cached data and eliminate the installation, monitoring, maintenance, disposal and replacement costs associated with BBUs. Available as a separate Kit: Adaptec Flash Module 600 

Intelligent Power Management - Reduce Power by up to 70% 
Adaptec Intelligent Power Management slashes power and cooling costs by spinning down idle disks and providing a lower power mode for active disks.
