SyQuest Technology

SyQuest 44 MB removable hard disk, with 24 mm US quarter coin for scale..

SyQuest Technology, Inc. NASDAQ: SYQT was an early entrant into the hard disk drive market for personal computers. The company was started in 1982 by Syed Iftikar who previously worked at Seagate.[1] Its earliest products were the SQ306R, a 5MB 3.9" (100mm) cartridge disk drive and associated Q-Pak cartridge for IBM XT compatibles and military applications.[2] Subsequently a non-removable medium version was announced, the SQ306F.

For many years SyQuest was the most popular means of transferring large desktop publisher documents such as advertisements to professional printers. SyQuest marketed their products as able to give personal computer users "endless" hard drive space for data-intensive applications like desktop publishing, Internet information management, pre-press, multimedia, audio, video, digital photography, fast backup, data exchange and archiving, along with confidential data security and easy portability for the road.

The Company was named partially after the founder because of a company meeting wherein it was decided that "SyQuest" ought to be a shortened name for "Sy's Quest".

Its earliest product family of 3.9" (100mm) cartridge disk drives and associated Q-Pak cartridges achieved limited success in government markets where removable media were required for security purposes.

In 1986 SyQuest announced the SQ555 and its SQ400 associated cartridge, a 44 MB 5¼-inch removable cartridge hard disk drive, using the industry standard 130 mm disk as its medium.[3] Double capacity versions, the SQ5110 and SQ800 were introduced in 1991. This generation of products became the de facto standard in the Apple Macintosh world to store, transfer and backup large amounts of data such as generated by graphic artists, musicians and engineers.[4]

SyQuest went public on the NASDAQ in 1991.

After 1997 SyQuest did not fare well in the market. Their core desktop publishing customers began increasingly to use CD-R media and FTP to transfer files, while Iomega's Zip drives dominated the small office/home office (SOHO) market. Over the period 1995 to 1997 sales declined, resulting in a series of losses. In the first quarter of 1997 those losses had been reduced to $6.8 million with net revenues increasing to $48.3 million. This compares to a net loss of $33.8 million, or $2.98 per share, on net revenues of $78.7 million for the same period the year before.

SyQuest filed for bankruptcy in late 1998, and portions of the company were subsequently purchased by Iomega Corp. in January, 1999. SyQuest retained the rights to sell their remaining inventory, on condition of renaming themselves SYQT in order to continue operations. For several subsequent years, a Web site at sold disk drives and media, and provided software downloads in support of those products. As of January 22, 2009, that Web site ceased to exist.


Syquest's product line included such devices as the following: (The 5.25" removable-disk hard drives with 44MB, 88MB, and 200MB capacities were mostly used on Macintosh systems via the SCSI interface.)
