Overview

The KIOXIA EXCERIA G3 SSD-CK1.0N5G3/N is a 1TB internal NVMe M.2 2280 SSD built on the PCIe Gen5 x4 interface. It delivers sequential read speeds up to 10,000 MB/s, dwarfing Gen4 drives and significantly reducing load times for demanding applications. Equipped with KIOXIA's homegrown BiCS FLASH 3D NAND and backed by a 5-year warranty, it offers both performance and peace of mind. This drive is designed for high-end PC builds where speed matters most—whether for gaming, creative work, or AI applications. It sits at the entry-to-mid tier of PCIe 5.0 SSDs, making Gen5 performance more accessible than ever before.

Compatibility Guide

The EXCERIA G3 uses the M.2 2280 (single-sided) form factor and requires a PCIe 5.0 x4 M.2 slot on your motherboard for full performance. It supports the NVMe 2.0c standard, ensuring compatibility with latest chipsets like Intel Z890 and AMD X870E. If installed in a PCIe 4.0 slot, it will still work but speeds will be capped at around 7,000 MB/s. A heat spreader label is pre-installed on the SSD, but using the motherboard's built-in heatsink is recommended for sustained workloads. The single-sided design also makes it compatible with slim laptops and compact builds where clearance is tight.

Product Info

Released in late 2024 with an approximate retail price of ¥64,800, the EXCERIA G3 is KIOXIA's entry-level PCIe 5.0 NVMe SSD. It carries a 5-year manufacturer's warranty and is backed by KIOXIA's Japanese production quality. Market positioning is as an affordable Gen5 option—ideal for users wanting to upgrade from Gen4 without breaking the bank. Key specifications include: Interface: PCIe 5.0 x4, NVMe 2.0c Form factor: M.2 2280 (single-sided) Capacity: 1TB Sequential read: up to 10,000 MB/s NAND: KIOXIA BiCS FLASH 3D NAND Warranty: 5 years

Best Use Cases

First-time Gen5 adopters: This drive offers a cost-effective entry into PCIe 5.0 storage, making it perfect for new high-performance builds. Creative professionals: Quickly load large video projects, 3D scenes, or asset libraries—reducing idle time and improving workflow. * Gamers: Faster level loading and texture streaming in modern games, especially those leveraging DirectStorage.

Things to Consider

To get the most out of the EXCERIA G3, you need a motherboard with a PCIe 5.0 M.2 slot. Such motherboards are still premium-tier products, so verify your board's specs before purchase. In a Gen4 system, the drive is still fast but loses its Gen5 advantage. Sequential write performance on this 1TB model is lower than premium Gen5 drives (like the EXCERIA PRO series), so users with heavy write workloads (e.g., frequent video exports) might want to consider a higher-tier option. Also, while the integrated heat spreader helps, sustained high-load operation benefits from active cooling or motherboard heatsinks.
