This article covers キオクシア KIOXIA 内蔵 SSD 1TB NVMe M.2 Type 2280 PCIe Gen 3.0×4 国産BiCS FLASH TLC 搭載 国内正規代理店5年保証 EXCERIA G2 SSD-CK1.0N3G2.

Overview

The KIOXIA EXCERIA G2 series sits in the entry-to-mid range of NVMe SSDs, offering a solid balance of performance and affordability. The model we're looking at today is the 1TB variant, part number SSD-CK1.0N3G2/N, which delivers sequential read speeds up to 2,100 MB/s and write speeds up to 1,700 MB/s over a PCIe 3.0 x4 interface. Inside, it leverages KIOXIA's own Japanese BiCS FLASH TLC 3D NAND memory, a key differentiator for reliability and consistency. This drive is ideal for users who want the speed benefits of NVMe without spending a premium on PCIe 4.0 hardware. It's a perfect fit for OS drives, game installations, and daily productivity tasks. The M.2 2280 form factor ensures broad compatibility with modern motherboards, and the installation process is as simple as inserting the module into an M.2 slot and securing it with a screw. Backed by a 5-year warranty from the authorized Japanese distributor, this SSD gives peace of mind for long-term use. Whether you're upgrading from a SATA SSD or building a budget-conscious gaming rig, the EXCERIA G2 1TB delivers noticeable speed improvements at a very reasonable price.

Compatibility Guide

Form factor: M.2 Type 2280 (80mm length) Interface: NVMe 1.3c (PCIe Gen 3.0 x4) Requires a M.2 slot (Key M) on your motherboard or laptop; works with both PCIe 3.0 and backwards-compatible PCIe 4.0 slots (speed will be capped at PCIe 3.0 bandwidth) Not supported for use in external enclosures per manufacturer warranty terms * Compatible with Windows, macOS, and Linux (standard NVMe driver support)

Product Info

Release window: Late 2021 (still actively sold as of 2026) Price range: Around ¥7,000–¥9,000 for the 1TB model, depending on sales and timing Warranty: 5 years through authorized distributor (Buffalo Direct), with TBW limit (200TB) – warranty ends if SSD Utility reports zero remaining life Market position: Entry-to-mid tier, optimized for cost-conscious NVMe upgrades. Offers competitive sequential speeds for the price, though lacks DRAM cache (uses HMB). * Software support: KIOXIA SSD Utility available for drive monitoring, firmware updates, and health checks.

Best Use Cases

Budget gamers upgrading from HDD/SATA SSD: You'll see dramatic improvement in game load times, level transitions, and OS boot speed. While PCIe 4.0 drives are faster, the real-world difference in gaming is marginal, making this an excellent value pick. Content creation secondary storage: For light video editing, photo libraries, and project files, this drive offers enough speed for quick previews and file transfers without breaking the bank. Pair it with a faster OS drive for maximum workflow efficiency. Secondary drive in a multi-SSD setup: Use a high-end PCIe 4.0 SSD for your OS and frequently used applications, then install the EXCERIA G2 as a game library or file storage drive. Cost-effective capacity expansion. First NVMe SSD for a new builder: Easy installation, long warranty, and reliable NAND make it a safe entry point. Beginners won't be overwhelmed by compatibility concerns.

Things to Consider

The PCIe 3.0 x4 interface limits sequential speeds to about 2,100 MB/s – significantly slower than modern PCIe 4.0/5.0 drives. However, for everyday tasks and gaming, the difference is often imperceptible. This drive uses HMB (Host Memory Buffer) instead of a dedicated DRAM cache. Under heavy random write workloads (e.g., compiling code, large databases), performance may lag behind DRAM-equipped competitors. TBW is rated at 200TB, which is modest. If you plan to write more than 100GB per day regularly, you might hit the TBW limit before the 5-year warranty expires. Check your usage patterns. Only purchase from authorized sellers (preferably Buffalo Direct or similar official distributors) to ensure full warranty coverage. Resold units without proper documentation may void the guarantee. * Not recommended for external USB enclosures – the drive is not validated for such use and warranty will not cover failures arising from external usage. ## FAQ
Q: Can I use this SSD in a PlayStation 5? A: No. The PS5 requires a PCIe 4.0 x4 NVMe SSD with at least 5,500 MB/s read speed. The EXCERIA G2 is PCIe 3.0 and does not meet Sony's requirements for internal expansion. Q: Does Windows 11 support this drive natively? A: Yes, Windows 11 has built-in NVMe drivers that will automatically recognize the drive during installation or after boot. UEFI mode installation is recommended for best performance. Q: Do I need an additional heatsink for this SSD? A: For typical desktop use, the motherboard's built-in M.2 heatsink is sufficient. Under sustained heavy writes, the drive may reach higher temperatures (70°C+), so good case airflow is beneficial. Adding a slim heatsink is optional but not strictly necessary.
