Areca ARC-1225-8I PCI Express x8 6Gbit/s RAID controller

8-Port PCIe 3.0 Internal 6Gbps SAS RAID Adapter SAS 2.0 is designed for much higher speed data transfer than previous available and backward compatibility with SAS 1.0. The 6Gb/s SAS interface supports both 6Gb/s and 3Gb/s SAS/SATA disk drives for data-intensive applications and 6Gb/s or 3Gb/s SATA drives for low-cost bulk storage of reference data. The ARC-12x5 family only support directly attach to 4/8 SAS/SATA drives without supporting the expand function.
