This article covers KIOXIA EXCERIA PLUS G4 2TB NVMe SSD.

Overview

The KIOXIA EXCERIA PLUS G4 2TB is a PCIe Gen5 NVMe internal SSD from Kioxia, featuring sequential read speeds up to 10,000 MB/s and write speeds up to 7,900 MB/s. It uses Japanese BiCS FLASH TLC NAND with 218 layers, delivering high power efficiency and density. Packaged in the standard M.2 Type 2280 form factor, this SSD is suitable for both desktop and notebook upgrades. It targets gamers and content creators who need fast storage for modern games, video editing, and large file transfers.

Compatibility Guide

The drive uses a PCIe Gen5.0 x4 interface with NVMe 2.0c protocol, and fits into any M.2 2280 slot. For full performance, a Gen5-capable M.2 slot is required; using a Gen4 slot will cap speeds at roughly 7,000 MB/s. Given the higher thermal output of Gen5 SSDs, a heatsink is strongly recommended — many motherboards include one, but aftermarket cooling may be necessary for sustained workloads. Check laptop dimensions if installing in a compact notebook, as some models may not physically accommodate the 2280 form factor.

Product Info

The KIOXIA EXCERIA PLUS G4 2TB (model SSD-CK2.0N5PLG4N) launched in 2025 as a mid-to-high-end SSD. It offers a 5-year warranty through authorized Japanese distributors (ending if the SSD Utility shows zero remaining life). Pricing online is around ¥42,996 (). The drive uses a DRAM-less design with 64 MB HMB (Host Memory Buffer) to maintain competitive random performance, paired with a Kioxia controller and BiCS FLASH TLC NAND.

Best Use Cases

  • Gamers: Speeds up to 10,000 MB/s drastically reduce game load times. With DirectStorage support, the PCIe Gen5 bandwidth enables faster asset streaming in compatible titles. - Content Creators: 4K/8K video projects and large 3D renders benefit from high sequential throughput. The 2TB capacity stores multiple projects without swapping drives. - High-End PC Builders: Pairs well with Ryzen 9000 or Intel Core Ultra platforms, eliminating storage bottlenecks in fully specced systems.

Things to Consider

Without a Gen5 M.2 slot, the drive will run at lower speeds, and the premium price may not be justified if you cannot use its full bandwidth. The DRAM-less design relies on HMB, so random write performance under heavy multi-threaded loads may not match DRAM-cache SSDs. Adequate cooling is essential; ensure your motherboard’s heatsink is sufficient or plan for an aftermarket solution. TBW is rated at 1200 TB, translating to roughly 3.3 years of 1 TB writes per day — more than enough for typical use.
