基于固态硬盘的星载海量存储阵列研究与设计

针对当前星载设备对低成本、标准化及快速组装、快速测试的需求,提出采用基于SATA接口的固态硬盘(SSD)作为存储模块研制星载存储设备。文章首先分析了星载存储技术发展特点、对存储设备的技术需求,以及固态硬盘自身的特点,然后分别从固态硬盘在星载应用中的必要性、可行性及其在应用中的优缺点进行探讨,并重点说明了在星载应用中需要攻克的关键技术及与数传/载荷分系统的融合方法,最后从硬件原理设计、软件层次设计等给出一种可行的设计方案,可为星载固存设备研制提供设计思路。

Research and Design of Onboard Mass Memory Array Based on SSD Disk

Focusing on the needs for lower cost,standardization and rapid assembly and test of onboard equipment,this paper adopts solid state drivers with SATA interface as onboard storage equipments.Having analysed the characters and the requirements of onboard storage technology,the paper discusses solid state drive in terms of necessity,feasibility and its advantages and disadvantages respectively,and analyzes its key technology and the issue how to integrate into data transmission/payload subsystem.Finally,a feasible design scheme is presented based on hardware schematic design and software hierarchical design.This paper can provide a new design idea for onboard solid storages.
