All-flash storage is a high-performance storage solution composed entirely of solid-state storage media, designed to replace traditional hard disk drives (HDDs) to improve data access speed and system efficiency. Its core features include low latency (typically less than 1 millisecond), high IOPS (500,000 to 1,000,000 input/output operations per second), and high bandwidth, making it suitable for high-concurrency, I/O-intensive applications.

Hybrid flash storage is a storage technology that combines flash memory (SSD) and traditional hard disk drives (HDD). It aims to improve the overall IOPS and response speed of the storage system by leveraging the high performance of flash memory, while achieving a balance between cost and performance by utilizing the large capacity advantage of HDD.

Distributed storage is a technology that integrates scattered storage resources into virtual storage devices through a network. Data is distributed across multiple independent nodes, aiming to solve the scalability, reliability, and performance bottlenecks of traditional centralized storage.

Computational storage is an innovative technology that integrates computing power directly into storage devices, aiming to solve the "memory wall" and "power wall" problems in the traditional von Neumann architecture. Its core idea is to migrate data processing tasks from the host CPU to the storage layer, reducing data transmission latency and energy consumption between storage and computing units.

Hyperconverged infrastructure (HCI) is a technology architecture that integrates IT infrastructure components such as computing, storage, and networking through software-defined methods, forming a highly integrated and easily managed overall system. Its core feature lies in using virtualization technology to abstract and pool resources, enabling dynamic allocation and management.
