This article covers KIOXIA EXCERIA ヒートシンク付き NVMe™ SSD 4TB。.

Overview

The KIOXIA EXCERIA Heatsink NVMe SSD 4TB is a high-capacity M.2 2280 internal SSD that leverages the PCIe Gen 4.0 x4 interface to deliver sequential read speeds of up to 7,000 MB/s. With a generous 4TB capacity, this drive is designed to handle the largest game libraries and creative project files without compromise. A standout feature is the pre-installed aluminum heatsink, which eliminates the need for aftermarket cooling solutions. This makes the drive particularly convenient for PlayStation 5 storage expansion, as the heatsink meets Sony's thermal requirements out of the box. The drive also maintains backward compatibility with PCIe Gen 3.0 systems. Positioned in the mid-to-high-end segment, this SSD targets gamers, content creators, and PS5 owners who need a large, fast, and hassle-free storage upgrade. It offers a compelling balance of capacity, speed, and ease of installation.

Compatibility Guide

The KIOXIA EXCERIA Heatsink NVMe SSD uses the M.2 2280 form factor and supports the NVMe 1.4 protocol. It is fully compatible with PCIe Gen 4.0 x4 slots and can also operate in Gen 3.0 x4 slots at reduced speeds. For PlayStation 5 users, the drive meets Sony's requirements for internal SSD expansion: it supports Gen 4 x4, exceeds the recommended read speed of 5,500 MB/s, and includes a heatsink that fits within the PS5's clearance limits. Installation is straightforward — simply insert the drive into the expansion slot and secure it with the provided screw. On PC motherboards, the integrated heatsink may interfere with some onboard M.2 heatsinks. Check your motherboard's layout before purchase. The drive is not recommended for ultra-thin laptops due to physical clearance constraints.

Product Info

Released in 2024, the KIOXIA EXCERIA Heatsink NVMe SSD 4TB is priced around ¥59,800 in Japan, making it a competitive option in the high-capacity Gen 4 SSD market. It comes with a standard 5-year manufacturer warranty (terms apply). This drive occupies the mid-to-high tier of the storage market, offering a rare combination of 4TB capacity and Gen 4 speeds at a relatively accessible price point. It is particularly well-suited for users who prioritize capacity without sacrificing modern interface speeds.

Best Use Cases

PS5 storage expansion: The pre-installed heatsink and Gen 4 compliance make this an ideal drop-in upgrade for PlayStation 5. With 4TB, you can keep your entire game library installed simultaneously, eliminating the need to re-download titles. High-capacity gaming PC: Modern AAA games often exceed 100GB each. A 4TB drive provides ample space for 20+ games, plus room for applications and media. The fast read speeds reduce level loading times significantly. * Content creation workstation: Video editors and 3D artists working with large project files (4K/8K footage, complex scenes) will benefit from the combination of high sequential throughput and large capacity. The drive can serve as a primary working drive for active projects.

Things to Consider

This SSD may not include a DRAM cache, which can impact random write performance, especially when handling many small files. For use as an OS boot drive, a DRAM-equipped model like the Samsung 990 Pro might offer better responsiveness. The advertised 7,000 MB/s read speed is a theoretical maximum. Real-world performance depends on your system configuration, thermal conditions, and workload. In a PCIe Gen 3.0 system, speeds will be capped at approximately 3,500 MB/s. Competitors such as the WD Black SN850X and Samsung 990 Pro offer DRAM caches and slightly better random performance, but at a higher cost per gigabyte. If your workload involves heavy random writes (e.g., database servers, VMs), consider those alternatives. For general gaming and PS5 use, this KIOXIA drive delivers excellent value.
