History 1988: Founding The company was founded in 1988 by Timothy J. Klein and David A. Snell, and is headquartered in Amherst, New York. All ATTO products are engineered and assembled in the United States. It is estimated that ATTO has delivered more than 2.5 million products to the market segments in a broad range of storage applications and environments. 1989–95: First Products The first ATTO product was the SiliconDisk, a SCSI-based solid-state disk, released in 1989. ATTO received its first OEM contract with Kodak shortly thereafter, in 1990. In 1992, ATTO introduced the ISA, EISA and MicroChannel (MCA) host bus adapters for the PC market at the Comdex trade show. By 1995, ATTO added to its product line yet again with the introduction of the ExpressPCI SCSI-3 Accelerator, which received the MacUsers Editor's Choice award that year. 1996–2008: New Technologies ATTO released its Fibre Channel host bus adapters, bridges and hubs in 1996. In 1999, ATTO introduced its first enterprise-class ATA-based RAID storage array. In 2002, the company released the iPBridge, an iSCSI to SCSI bridge. In the early 2000s, ATTO started a focus on the Fibre Channel market, developing and releasing the Celerity line of Fibre Channel host bus adapters in 2003 with 1Gb connectivity. By 2005, ATTO expanded its Celerity offerings with the 4Gb host bus adapters, as well as introducing the FibreBridge storage controller for data centers and the FastStream Fibre Channel RAID controllers. In 2007, ATTO stepped into the SAS/SATA market with ExpressSAS RAID and host bus adapters. The following year, ATTO released 8Gb Fibre Channel and 6Gb ExpressSAS adapters, and in 2009 the company rolled out the first 8Gb Fibre Channel storage controller. ATTO introduced its FibreConnect family of switches in 2010 and introduced a revised product in 2012, providing scalable, end-to-end SAN connectivity. In 2011, ATTO released its first FastFrame network interface cards and converged network adapters, enabling connectivity to Ethernet networks. In 2012, ATTO introduced its ThunderLink and ThunderStream devices, the company's first Thunderbolt enabled products. 2015–Present: New Developments By 2015, ATTO had expanded its FastFrame offering to include
