MiniStor Peripherals, Inc., was a public American computer hardware company based in San Jose, California, and active from 1991 to 1995.

As customer surveys overwhelmingly saw PC Cards as the breakout application for 1.8-inch drives, MiniStor decided to focus their efforts on this segment.

[12] The MiniPort drives had a rated MTBF of one hundred thousand stops and starts, significantly lower than Intégral's one million.

[14] MiniPort's drives parked the heads into the loading zone via a mechanical latch instead of energizing a magnetic coil, a technique first used by the founder's former employer Maxtor that reduced power draw.

[22] MiniStor filed its initial public offering in August 1994, underwritten by Punk, Ziegel & Knoell and D. Blech & Company.

[24][25] MiniStor briefly manufactured desktop 3.5-inch hard drives before filing Chapter 11 bankruptcy in April 1995 with plans to liquidate its assets.
