TRENDS IN COTS STORAGE SOLUTIONS FOR DATA ACQUISITION SYSTEMS

摘要

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.
