ATTO Technology's ExpressSAS RAID Adapters are First to Bring the
Power of Serial Attached SCSI Storage to the Macintosh Platform

MACWORLD EXPO, SAN FRANCISCO -- January 9, 2007 -- ATTO Technology,
Inc., global leader of storage connectivity and infrastructure
solutions for data-intensive computing environments, will showcase
its new ExpressSAS RAID adapters at the MacWorld Expo, Booth #S1243.

With the introduction of the ExpressSAS product line, ATTO becomes
the first manufacturer to deliver the affordable performance of
Serial Attached SCSI RAID technology to the Macintosh platform.
Designed to take full advantage of the high-speed PCI Express I/O
architecture of Apple's Intel-based MacPro workstations and Xserve
servers, ATTO's 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.

ATTO's delivery of Apple-compatible SAS RAID solutions is the latest
chapter in the company's long history of support and innovation for
the Mac platform. ATTO has spent the past 18 years developing product
for the Macintosh market and working closely with Apple to deliver
superior, high-quality products with proven interoperability and
compatibility in the Apple market. In addition to the new ExpressSAS
RAID adapters, ATTO's ExpressPCI SCSI adapters and Celerity 4-Gb
Fibre Channel host adapters have been certified on the Intel
Xeon-based MacPro and Xserve systems, complete with standard and
customized drivers for Mac OS X users to allow for effortless
integration into Apple environments.

"ATTO's commitment to the Macintosh market has never wavered and the
combination of Apple's new Intel-based workstations and servers with
ATTO's SAS RAID technology provides Mac users with powerful yet
affordable solutions to tackle the most data-intensive IT and digital
content applications," said Ed Tierney, director of marketing at ATTO
Technology.

ATTO's new ExpressSAS RAID adapters are the industry's first and only
products with a true low-profile form factor that fit standard-length
PCI Express slots, making them ideal for compact designs such as the
Xserve systems where real estate is at a premium. The ExpressSAS
products are also the industry's only low-profile line of adapters
offering user selectable port configuration options, enabling
customers to select the optimal mix of internal and external SAS
connections.

These new RAID controllers leverage the power of ATTO's
customer-proven high-performance RAID technology -- including the
company's proprietary Advanced Data Streaming (ADS) Technology that
alleviates data transfer bottlenecks -- and Intel's new 800MHz PCIe
Intel IOP348 I/O Processors with integrated high-performance XScale
technology to meet the most demanding performance requirements of
data intensive applications, including transactional databases, email
servers, large server farms and digital media.

Featuring advanced fault-tolerant features that 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, the ATTO ExpressSAS R348 and R380 adapters deliver an
intelligent and robust low-profile RAID solution. The SAS and SATA II
support make it easy to create cost-effective multi-tiered storage
solutions in a single cabinet, utilizing cost-correct SATA drives for
secondary storage while staging critical primary data on
higher-performance SAS disks. These adapters will support standard
RAID levels 0, 1, 5, 6, 10, 50 and 60 and feature ATTO's exclusive
DVRAID, making them capable of handling the most demanding Mac-based
digital media applications, such as 2K and 4K film, multiple layers
of complex, uncompressed real-time effects, and high definition video
editing.

The ATTO ExpressSAS RAID Adapters combine x8 PCI Express technology
and SAS speeds for high-performance server environments and
applications. SAS is the next generation SCSI interface that delivers
significant improvements in scalability, performance, reliability,
and flexibility over parallel SCSI by leveraging a serial
architecture for data transport. PCI Express is a low-cost, highly
scalable serial technology that delivers added performance by
increasing the I/O capacity while eliminating bus contention. This
allows for faster and more efficient performance with reduced I/O
bottlenecks.
