The Kingston A400 SA400M8/480G is a 480GB M.2 2280 SATA SSD designed to provide fast, responsive storage for compatible desktop PCs and notebooks. With SATA Rev. 3.0 connectivity and sequential speeds of up to 500MB/s read and 450MB/s write, it delivers a significant performance improvement over traditional mechanical hard drives.

Description

The Kingston A400 480GB M.2 2280 SSD (SA400M8/480G) combines solid-state reliability with a compact M.2 form factor, making it an excellent storage upgrade for compatible desktop and notebook computers.

Using a SATA Rev. 3.0 (6Gb/s) interface, the A400 delivers sequential read speeds of up to 500MB/s and sequential write speeds of up to 450MB/s for the 480GB capacity. It is also backward-compatible with SATA Rev. 2.0 systems, although actual performance depends on the host system and interface.

The compact M.2 2280 design measures approximately 80 × 22 × 1.35mm, making it suitable for systems with limited internal space. With no moving mechanical components, the SSD is resistant to shock and vibration and provides quieter, cooler operation than traditional hard drives.

The 480GB capacity provides ample space for operating systems, applications, documents, media, and everyday files, making it suitable for system upgrades, storage expansion, and general desktop or notebook workloads.

Compatibility

The SA400M8/480G is designed for desktop PCs and notebooks equipped with an M.2 2280 slot that supports SATA-based M.2 SSDs.

Important: M.2 is a physical form factor, not an interface. This drive is SATA, not NVMe/PCIe. Therefore, an M.2 slot that supports only NVMe/PCIe drives may not be compatible.

Recommended Applications

Desktop PC upgrades
Notebook upgrades
Operating-system storage
Application and software storage
General-purpose computing
Office and business systems
Replacing a traditional HDD
Storage expansion in compatible M.2 SATA systems
Everyday file and media storage

Performance Note

Kingston’s quoted speeds are based on ATTO testing and represent maximum baseline performance under specified conditions. Actual performance can vary depending on the host hardware, motherboard, operating system, software, workload, and available SATA bandwidth.

Compatibility Note

Before purchasing or installing, verify that the target system supports an M.2 2280 SATA SSD. Do not assume compatibility solely because the computer has an M.2 slot.
