Overview
ExcelStor Technology, also known in Chinese as 易拓科技, was established in 2000 as a small hard disk drive manufacturer in China. The company subsequently developed a broader role as a contract manufacturer and systems integrator, combining branded storage products with manufacturing and engineering services for established technology companies. Its principal manufacturing facility was in Shenzhen, China, while its engineering footprint included a research and development center in Longmont, Colorado, in the United States. A significant early step in ExcelStor's development was its acquisition of the assets of bankrupt Conner Technology PLC, including the company's products and factory. This gave ExcelStor additional manufacturing capability and product-related resources as it sought to establish itself in the competitive disk-drive industry. The company operated in a sector dominated by much larger international manufacturers, making partnerships and outsourced production important elements of its business model. ExcelStor became especially visible through a 2002 agreement with IBM. Under that arrangement, ExcelStor manufactured and sold a 40 GB version of IBM's Deskstar 120GXP hard-drive series under the ExcelStor name, while IBM also marketed the drives under its own brand. The relationship continued after Hitachi acquired IBM's storage division. In 2003, the agreement was expanded to cover 40 GB and 80 GB versions associated with Hitachi's Deskstar 7K250 series. These arrangements positioned ExcelStor as both a branded-drive supplier and an original-equipment manufacturing partner for larger storage companies. The company's product activity was not limited to conventional hard drives. ExcelStor also produced models incorporating specialized firmware functions, including multi-boot management and backup-and-restore capabilities. These features reflected an attempt to differentiate storage hardware through software functionality rather than relying solely on capacity or mechanical specifications. Beginning in 2004, ExcelStor manufactured some products for Iomega, including products associated with the REV removable-storage platform. Its relationship with Iomega later developed into a proposed corporate transaction. In 2007, Iomega announced plans to acquire ExcelStor through a stock exchange valued at approximately $315 million. The transaction did not close. In 2008, as Iomega itself was being acquired by EMC Corporation, Iomega paid a reported $7.5 million termination fee connected with the failed ExcelStor transaction. ExcelStor also experienced organizational contraction during this period. In 2007, it laid off 20 of the 28 employees at its Longmont research and development center. Public reference material provides limited information about the company's later operations, ownership structure, leadership, revenue, and present-day commercial status. It is therefore best characterized historically as a China-linked storage manufacturer, contract producer, and systems integrator whose most documented period involved partnerships with IBM, Hitachi, and Iomega.
History
ExcelStor Technology was founded in 2000 as a small hard disk drive manufacturer. Its early development included the acquisition of bankrupt Conner Technology PLC, together with that company's products and factory. The transaction provided ExcelStor with additional manufacturing assets as it entered a highly competitive storage market. The company operated manufacturing facilities in Shenzhen, China, and maintained a research and development center in Longmont, Colorado. Rather than competing only as an independent disk-drive brand, ExcelStor pursued a mixed model encompassing branded products, contract manufacturing, and systems integration. This model enabled it to work with larger technology companies that possessed stronger distribution or brand recognition. In 2002, ExcelStor entered into an agreement with IBM to manufacture and sell a 40 GB version of IBM's Deskstar 120GXP series under the ExcelStor name. IBM also marketed the drives under its own brand. After Hitachi acquired IBM's storage division, the relationship was extended in 2003 to cover 40 GB and 80 GB drives connected with Hitachi's Deskstar 7K250 series. ExcelStor also made drives with nonstandard firmware capabilities, including multi-boot management and backup-and-restore functions, giving some products features beyond basic data storage. From 2004 onward, ExcelStor manufactured some products for Iomega, including products in the REV removable-storage family. The commercial relationship later led to a proposed acquisition. In 2007, Iomega announced that it intended to acquire ExcelStor in a stock transaction valued at approximately $315 million. The proposed deal was not completed. In 2008, Iomega paid a termination fee reported at $7.5 million as Iomega was being acquired by EMC Corporation. The 2007 period also brought a reduction in ExcelStor's United States engineering presence. The company dismissed 20 of the 28 employees at its Longmont research and development center. Available reference material does not establish the company's subsequent corporate status, later product releases, executive leadership, financial performance, or current ownership in sufficient detail. ExcelStor's documented historical identity is therefore that of a China-based hard-drive producer and storage contract manufacturer with international OEM relationships.
