Application comparison between Solid State Drives (SSD) and Hard Disk Drives (HDD) in big data storage
固态硬盘（SSD）与机械硬盘（HDD）在大数据存储中的应用对比

摘要

大数据时代对存储设备的性能和容量提出了更高的要求，固态硬盘（SSD）和机械硬盘（HDD）作为两种主流存储介质，在大数据存储应用中表现各异。本文围绕SSD与HDD在大数据存储中的性能差异、成本效益、可靠性及应用场景进行了深入对比分析。通过探讨两者的技术特点及应用优势，旨在为大数据系统选择合适的存储方案提供理论支持和实践参考。SSD在读写速度和系统响应时间方面具有明显优势，而HDD则在成本和存储容量方面更具竞争力。综合考虑性能与经济性，是实现高效大数据存储的关键。

Abstract

The era of big data imposes higher requirements on the performance and capacity of storage devices. As two mainstream storage media, Solid State Drives (SSD) and Hard Disk Drives (HDD) exhibit different performances in big data storage applications. This paper conducts an in-depth comparative analysis of SSD and HDD in terms of performance differences, cost-effectiveness, reliability, and application scenarios in big data storage. By exploring their technical characteristics and application advantages, it aims to provide theoretical support and practical references for selecting appropriate storage solutions for big data systems. SSD has obvious advantages in read/write speeds and system response time, while HDD is more competitive in terms of cost and storage capacity. Comprehensive consideration of performance and economy is the key to achieving efficient big data storage.
