Qualstar Makes Data Storage Interfacing Easier with the ATTO ExpressSAS 12Gb H1280 GT PCIe 4 SAS HBA

The data storage provider partners with ATTO to add the fast and feature rich new HBA to its product lineup.


Leading data storage solutions provider Qualstar Corporation (OTC Markets: QBAK) makes it even easier to manage a tape-based storage solution with the addition of ATTO ExpressSAS® 12Gb H1280 GT SAS/SATA host bus adapters to its extensive product catalog. This new host bus adapter (HBA) is one of only two currently on the market that utilizes the x8 PCI Express 4.0 host interface, offering the fastest available direct connection to SAS storage devices.

New from ATTO Technology, Inc., the ATTO ExpressSAS H1280 GT 12Gb/s PCIe 4 SAS HBA provides blistering 12 Gb/s transfer speeds for SAS. It has eight external ports, which can be configured for redundancy, and can support as many as 2,048 end devices. Exclusive built-in latency-reducing technology ensures a consistent stream of data to the storage device. This, in turn, speeds up write times and reduces tape wear because it will not need to make multiple passes due to data flow interruptions. Additionally, all 12Gb HBA adapters include ATTO PowerCenter Pro, an integrated software RAID solution that brings the performance and protection of RAID to attached storage devices.

“Qualstar is dedicated to continually expanding its range of products to address all of our customers’ potential needs,” says Arun Vaishampayan, vice president of global sales for Qualstar. “ATTO ExpressSAS HBAs provide the superior functionality that our customers have come to expect, and we are excited to be able to offer it directly to them through this partnership.”

Impressive specifications aside, ExpressSAS H1280 GT is particularly notable for its effortless, user-first design. It is compatible with Windows®, macOS®, and Linux® and is compatible with intuitive but powerful software tools provided by ATTO. A low-profile design not only provides better airflow over the device but also makes installation easier. And if anything ever goes wrong, a bevy of diagnostic and monitoring tools can pinpoint the failure—even down to individual cables.

“ExpressSAS 12Gb/s HBAs are a great interfacing solution for customers managing tape-based data storage solutions,” says Tom Kolniak, senior director of marketing, product management, and alliances at ATTO. “Given our 30-year proven track record and Qualstar’s commitment to excellence, this partnership is a natural fit.”
