Overview

The KIOXIA EXCERIA PLUS G3 (model SSD-CK1.0N4PLG3N) is a PCI Express 4.0 NVMe M.2 2280 internal SSD with a 1TB capacity. It offers sequential read speeds up to 5,000MB/s and write speeds up to 3,900MB/s, placing it firmly in the mid-range of PCIe 4.0 drives.
What sets this drive apart is its use of KIOXIA's own BiCS FLASH 3D TLC NAND, manufactured in-house. This gives buyers confidence in both quality and supply chain. The drive is ideal for gaming PCs, content creation workstations, and as a high-speed boot drive for any desktop or notebook with an M.2 slot.
The EXCERIA PLUS G3 series has been on the market since late 2023 and is widely available from major retailers. It comes with a 5-year limited warranty (terms apply) and is backed by KIOXIA's official Japanese distribution network.

Compatibility Guide

The drive uses the M.2 Type 2280 form factor (22x80mm) with a single-sided design, making it compatible with most motherboards, thin laptops, and even some mini PCs. It runs on the NVMe 1.4 protocol over a PCIe Gen4 x4 interface. If installed in a PCIe 3.0 slot, it will operate at Gen3 speeds (around 3,500MB/s sequential read).
KIOXIA provides the SSD Utility software for Windows to monitor drive health, update firmware, and manage partitions. The drive is recognized as a standard NVMe device on Linux and macOS, but the utility is Windows-only.

Product Info

Released in late 2023, the EXCERIA PLUS G3 sits at the mid-range tier of KIOXIA's consumer SSD lineup. The 1TB model is currently priced around ¥28,800 on Japanese online retailers (as of September 2026). Key specs include: controller (proprietary, details undisclosed), HMB (Host Memory Buffer) instead of DRAM cache, BiCS FLASH TLC 112-layer NAND, 600TB TBW, 1.5 million hours MTBF, and a 5-year warranty.

Best Use Cases

Gaming PC build: With 1TB capacity and fast sequential reads, this drive can hold the OS and a library of modern AAA games. DirectStorage-enabled titles will benefit from the NVMe bandwidth. Suitable for both new builds and upgrades.
Content creation (video/photo editing): Fast read/write speeds improve timeline scrubbing in 4K editing and accelerate export times. The 1TB capacity is enough for a working project cache plus active project files.
Secondary drive for laptop or thin desktop: The single-sided design and moderate heat output make it viable for tight spaces where a thick SSD with heatsink wouldn't fit. However, official support forbids use in external enclosures.
Budget-conscious performance seeker: Compared to top-tier Gen4 drives (e.g., Samsung 990 Pro), the EXCERIA PLUS G3 offers 90% of the performance at a noticeably lower price, making it a smart pick for value-focused builders.

Things to Consider

The lack of DRAM cache (HMB only) means sustained random write workloads may not match DRAM-equipped rivals under heavy load. For typical gaming and office use, the difference is negligible. Also, the drive arrives unformatted—you must initialize it before first use.
Competitors like the Samsung 980 Pro or WD SN850X offer slightly higher peak speeds, but the KIOXIA usually costs less. If you need the absolute fastest Gen4 drive, look elsewhere. For balanced daily use, this is a strong contender.
Heat can be an issue under prolonged heavy writes. No heatsink is included, so consider an aftermarket M.2 cooler if your motherboard lacks one.

FAQ

Q: Can I use this SSD in a PlayStation 5?
A: Physically it fits, but the PS5 requires a minimum sequential read of 5,500MB/s; this drive only meets 5,000MB/s. Sony does not officially list it as compatible, and performance may be suboptimal.
Q: What is the difference between the 1TB and 2TB models?
A: Capacities differ, and TBW scales proportionally (600TB for 1TB, 1,200TB for 2TB). All other specs (speed, interface, warranty) are identical.
Q: Does KIOXIA provide cloning software?
A: No. You'll need a third-party tool like Acronis True Image, EaseUS Todo Backup, or the free Macrium Reflect. The drive is unformatted, so cloning requires initializing it first.
