ARC-1680 series/ARC-1681
(8 port PCIe/PCI-X to SAS RAID Adpater)

Areca high-performance PCIe/PCI-X to SAS RAID host adapter can provide up to (128) SAS/SATA ll peripheral devices using SAS expanders. The adapters are based on the same RAID kernel of field-proven external RAID controller. Applications that benefit most features from these controllers include NAS, server RAID solutions, web servers, supercomputing, near-line backup, security systems and streaming applications.
