Adaptec ASR-3405

The ASR-3405 is the junior controller with RAID5 support from Adaptec’s new series featuring the Unified Serial architecture.

Although a junior model in the series, the ASR-3405 is quite advanced in its characteristics. It has a PCI Express x4 interface, SAS and SATA (NCQ + 3Gbps) interfaces for the HDDs, an Intel 80333 processor clocked at 500MHz, 128 megabytes of DDR2 SDRAM, and an internal mini-SAS SFF-8087 connector. It allows to install a battery to power the cache memory chips and supports the following RAID types: 0, 1, 5, 6, 10, 50, and 60. So, it has everything you may want from a RAID controller. You’ll see soon how this new controller compares with the others in terms of performance.
