JT Storage

JT Storage (also known as JTS Corporation, JTS Corp and JTS) was a maker of inexpensive IDE hard drives for personal computers based in San Jose, California. It was founded in 1994 by "Jugi" Tandon—the inventor of the double-sided floppy disk drive and founder of Tandon Corporation—and Tom Mitchell, a co-founder of Seagate and former president and Chief Operating Officer of both Seagate and Conner Peripherals.

The company later merged with Jack Tramiel's Atari Corporation, and was declared bankrupt in 1999.

JTS initially focused on a new 3" form-factor drive for laptops. The 3" form factor allowed a larger drive capacity for laptops with the existing technology. Compaq Computers was actively engaged in qualifying these drives and built several laptops with this form factor drive. Lack of a second source was a major obstacle for this new form factor to gain a foothold; JTS licensed the form factor to Western Digital to attempt to remedy this problem. Eventually, as 2.5" drives became cheaper to build, interest in the 3" form factor waned, and JTS and WD stopped the project in 1998.

JTS by then had become a source of cheap, medium-performance 3.5" drives with 5400 RPM spindles. The drives, produced in a factory in India (the factory was in the Madras Export Processing Zone in the suburbs of the Southern Indian city of Madras, now known as Chennai), were known for poor reliability. Failure rates were very high and quality control was inconsistent: good drives were very good, still running after 5 years, whereas bad drives almost always failed within a few weeks. Because of their low-tier reputation, JTS drives were rare in brand-name PCs and most frequently turned up in home-built and whitebox PCs. Product lines included Palladium and Champion internal IDE hard drives.
