Did you know ATTO ExpressSAS SAS/SATA HBAs include features and technologies no other SAS card has?

ExpressSAS host bus adapters with ATTO WriteStop provide a comprehensive digital forensics storage connectivity solution, while Advanced Data Streaming technology manages latency for high-bandwidth environments. And that's just the beginning - See below to see why ExpressSAS HBAs are the best choice for your workflow.

ExpressSAS HBAs are now ready for the next evolution in computing with their latest PCIe 4.0 product portfolio.

Flexible connectivity solutions

ATTO ExpressSAS HBAs are available with a wide selection of 8, 12 and 16 port options to support a dense connection to storage from rack-mounted servers and workstations in datacenter, data warehousing, video on demand and other high availability, high performance applications.

RAID Protection at No Extra Cost

ExpressSAS HBAs feature ATTO PowerCenter Pro, a game changing software technology that adds hardware RAID capabilities at the cost of a host bus adapter, and without additional drivers or complicated set-up. PowerCenter Pro is the most effective way to improve performance while also protecting data.

Performance Engineered

ATTO ExpressSAS HBAs incorporate powerful hardware and software elements to manage latency in real-time environments. Exclusive Advanced Data Streaming (ADS) Technology maximizes CPU processes to deliver smooth and reliable data transfers and the highest consistent performance.

Competitor Products: Disrupted transfer with peaks and drops.  Transfer rate dips below optimal performance levels
ATTO Products with ADS Technology: ATTO ADS technology stabilizes data streams, providing more optimal throughput than the competition.

Efficiently Share Memory

ATTO 12Gb ExpressSAS HBA drivers are architected for multi-CPU platforms. ATTO NUMA aware hardware drivers consider the I/O patterns to ensure that driver resources are located close to the system I/O resulting in reduced latency for streaming and high IOPS workflows.

Develop Unique, Quick to Market Solutions

OEMs and system integrators can take advantage of ATTO Target Mode Software Development Kits (SDK) or industry standard driver options to create unique branded storage and appliance solutions. Through a more tightly integrated driver, an ATTO ExpressSAS SDK provides integrators complete control, ownership and flexibility in creating custom capabilities to address specific product designs.

Enterprise OS Support

Extensive operating system support includes major software releases for Linux, Windows, Windows Server, macOS, illumos, VMware EXSI Server, and FreeBSD.
