History (1993): 3.5-Inch 105MB Cartridge Drive

This article comes from the Computer History Museum.

SyQuest 3.5-Inch (105/270MB) (1993-1998)

The SyQuest 105MB cartridge (SQ310) was introduced in Spring 1993, and was a removable rigid disk data storage format with a 3.5-inch form factor.

Later in the year, a 270MB version (SQ270) was introduced.

Neither were compatible with previous SyQuest disk formats, nor with the 3.5-inch EZ135 and EZFlyer that followed them. 

The 270MB drives can read and write to the 105MB cartridges.

SyQuest disk were popular in the graphics arts and printing industries with more than a million units sold by 1994, but because of the huge installed base of the SyQuest 5.25-inch drives, the 3.5-inch cartridge formats were not as successful.
