Designed to take advantage of the high-speed PCI Express I/O architecture of Apple's Intel-based MacPro workstations and Xserve servers, ExpressSAS RAID adapters deliver the high performance required for digital media production and delivery, streaming applications, I/O intensive server requirements and other data intensive OS X-based applications.

The ExpressSAS RAID adapters feature a low-profile form factor that fit standard-length PCI Express slots, making them suitable for compact designs. The ExpressSAS products also offer users selectable port configuration options, enabling customers to select the optimal mix of internal and external SAS connections.

The new RAID controllers leverage Atto's high-performance RAID technology and Intel's new 800MHz PCIe Intel IOP348 I/O processors with integrated XScale technology. Advanced fault-tolerant features include hot swap, hot spares, online capacity expansion, battery back-up, and optimized disk utilization for SAS drives, SATA II drives, or any combination of the two.

These adapters support standard RAID levels 0, 1, 5, 6, 10, 50 and 60, and feature Atto's DVRAID, making them capable of handling demanding Mac-based digital media applications, such as 2K and 4K film; multiple layers of complex, uncompressed realtime effects; and high definition video editing.
