The Addonics SATA II PCI-X family of controllers are one of the fastest SATA controllers in the market. Incorporating the latest SATA II ASIC from Silicon Image, the controller is designed to work with fast PCI-X BUS to ensure maximum data throughput of 3 Gbits/sec per port. The standard RAID controller allow 4 SATA/ SATA II hard drives to be configured as RAID 1, RAID 0, RAID 1+0, RAID 1+S or as 4 individual drives. Whereas the RAID5/JBOD controller supports configuration of RAID 1, RAID 0, RAID 1+0, RAID5 and JBOD that combine all drives into one large volume.

With 4 drive are stripped together (configured as RAID 0), throughput up to 200 Mbytes/sec can be achieved using standard 7,000 RPM SATA hard drive (see benchmark test result below). Together with the Addonics optional Disk Array 4SA or 3SA system, you can add high performance storage system rivaling the traditional SCSI storage at less than half of the cost.

*Note: It is common in RAID5 configuration that the WRITE speed performs slower than READ. Depending on system hardware, the WRITE performance can drop to 25% of the READ speed. This performance difference does not affect general database application where majority of the transations are READ commands. For applications that require large files transfer or continuous writing of data on the the hard drive such as video editing, RAID5 configuration may not be desirable.
