Overview

The KIOXIA EXCERIA PLUS G4 2TB is an M.2 NVMe SSD leveraging the PCIe 5.0 interface. It delivers astonishing sequential read speeds up to 10,000 MB/s and write speeds up to 8,200 MB/s, making it ideal for rapid game loading and 4K/8K video editing workflows. Built with BiCS FLASH 218-layer 3D TLC NAND flash, this DRAM-less drive still achieves excellent performance through efficient controller design. Compared to the previous EXCERIA PLUS G3 series, the G4 offers up to 80% better power efficiency for sequential reads, minimizing heat generation. Market positioned as a mid-to-high-end PCIe 5.0 SSD, it strikes a strong balance between cutting-edge speed and value.

Compatibility Guide

The drive uses the M.2 2280 form factor and requires a PCIe 5.0 x4 interface for full performance. It will operate in a PCIe 4.0 slot but will be limited to Gen4 speeds. Best performance is achieved on Intel 12th-gen (Alder Lake) or newer, or AMD Ryzen 7000 series and later platforms. The host motherboard must have an M.2 slot with Key M. A heatsink-equipped motherboard is recommended, but the drive's own thermal label design helps manage heat adequately. No additional power supply considerations are needed; the drive draws power directly from the M.2 slot.

Product Info

Launched in late 2025, the EXCERIA PLUS G4 2TB is available through and major electronics retailers. It comes with a 5-year manufacturer warranty. In terms of market positioning, it sits as a cost-effective PCIe 5.0 SSD undercutting many competitors while maintaining high performance for its class. The TBW (Total Bytes Written) rating is 1400TB for the 2TB model, ensuring excellent endurance for heavy workloads.

Best Use Cases

First, gamers who want ultra-fast loading times for AAA titles, especially games that utilize DirectStorage, will see significant benefits. Second, creative professionals such as video editors working with large 4K/8K raw footage will appreciate the 10,000 MB/s sequential read performance for fast file transfers. Finally, builders of new PCIe 5.0-ready systems who want future-proof storage without overspending will find this drive a compelling choice.

Things to Consider

To fully utilize the PCIe 5.0 bandwidth, a compatible platform is mandatory; otherwise, the drive will operate at Gen4 speeds, roughly halving its peak throughput. Since the drive is DRAM-less, sustained heavy random write workloads may fall behind DRAM-equipped counterparts. At around ¥62,400, the 2TB model carries a premium, so budget-conscious users might consider the EXCERIA PLUS G3 series as a cost-effective alternative. Thermal performance is acceptable for a PCIe 5.0 drive, but good case airflow is recommended to maintain consistent speeds during prolonged use.
