Adaptec Delivers the Industry's First Single-Channel Ultra320 SCSI Host Bus Adapter for the PCI Express Interface

Market Wire, March, 2007

Adaptec, Inc. (NASDAQ: ADPT), a global leader in storage solutions, today announced the industry's first low-profile Ultra320 SCSI single-channel host bus adapter (HBA) for the PCI Express (PCIe) interface. Designed to protect investments in existing hardware, while delivering support for the industry's latest host connection, the Adaptec 29320LPE Ultra320 SCSI HBA delivers PCIe connectivity and unmatched system flexibility for attaching SCSI devices to a workstation or server including tape drives, tape libraries, disk drives and RAID arrays.

For companies faced with the need to maximize existing infrastructure investments due to a flat or declining IT budget, the Adaptec 29320LPE Ultra320 SCSI HBA offers seamless backward compatibility between previous-generation SCSI devices and the new PCIe host bus interface. The exclusive Adaptec SpeedFlexTM technology enables the Adaptec 29320LPE Ultra320 SCSI HBA to ensure maximum performance while maintaining full backward compatibility with legacy equipment. By increasing the performance capabilities of older devices, the Adaptec 29320LPE Ultra320 SCSI HBA leverages and protects a company's IT investments, while eliminating the potential risks associated with transitioning to an Ultra320 technology.

"Traditional SCSI continues to be the primary technology for companies who must store and backup essential data on disk drives and tape libraries in their existing infrastructure," said Suresh Panikar, director of marketing for the Data Protection Solutions Group at Adaptec. "With the industry's first PCIe solution that gives companies expanded connectivity and high performance for all SCSI devices regardless of generation, Adaptec is enabling IT departments to leverage their existing investment without sacrificing performance or network capabilities."

The new Adaptec 29320LPE Ultra320 SCSI controller will be shipping and available through worldwide distributors and resellers on March 30, 2007. Pricing for the 29320LPE is $240 U.S. MSRP.
