This paper discusses data storage requirements for Smart displays which are based of a display with a single-board computer built into the casing. This paper evaluates the ability of three of the most popular COTS data storage solutions - mechanical disk, ruggedized mechanical disk and solid-state flash disk - to meet these requirements today and in the future. It addresses issues of capacity, data reliability, endurance, form factor, cost and security features.

This paper discusses data storage requirements for data acquisition systems, and evaluates the ability of three of the most popular COTS data storage solutions - mechanical disk, ruggedized mechanical disk and solid-state flash disk - to meet these requirements today and in the future. It addresses issues of capacity, data reliability, endurance, form factor, cost and security features. It concludes with a discussion of trends to implement high-speed serial interfaces in data acquisition systems, and the challenges that they pose for COTS storage solutions.

Rugged, reliable and secure data storage is of major concern to engineers designing Airborne Intelligence, Surveillance, Reconnaissance (ISR) systems. Operation under harsh conditions of shock, vibration and high altitude in extreme temperature ranges is an essential requirement. Due to its rotating mechanism, a mechanical disk cannot provide top-level data reliability in such an environment. Other Commercial Off The Shelf (COTS) solutions can replace mechanical disks. This paper describes some of these alternatives and highlights their cost-effectiveness. One alternative is a ruggedized mechanical disk, a mechanical disk sealed in a rigid cartridge. Another alternative is the solid-state flash disk that, like the mechanical disk, retains data when power is off, and is a “drop-in replacement” for the mechanical disk for reliability in harsh environments. Flash disk manufacturers incorporate special methods to enhance endurance and reliability for military designers.
This paper also describes the mandatory requirements of the DoD, NSA and the US Air Force for erasing confidential data in storage devices. This issue is vital, especially since the P-3 landed forcibly on China’s soil. Some flash disk vendors meet security requirements with Fast Secure Erase and Sanitize, enabling data declassification in seconds, even without power.
