HighPoint Technologies releases the RocketRAID 2640X4, with a PCI-Express x4 SAS RAID 5 controller. It supports RAID levels (0, 1, 5, 10 and JBOD) and offers the flexibility to be able to support either 15,000 RPM SAS hard drives for performance or low cost SATA hard drives for capacity. Performance bottlenecks occur with PCI-Express x1 bus speeds limiting SAS performance throughput to SATA speeds.

Disks with SAS interfaces are designed to meet the performance and reliability characteristics required for enterprise-class server arrays and RAID systems, says the manufacturer. The ability to deploy either type of drives allows the computer system to be optimized for specific application and cost requirements.
