KIOXIA added a 4 TB model to its Exceria G3 M.2 Gen 5 NVMe SSD line, expanding a series that debuted last December with 1 TB and 2 TB options. The new drive uses a Phison E31T DRAMless controller and KIOXIA’s 218‑layer BiCS8 3D QLC NAND.

Performance mirrors the 2 TB variant: up to 10 GB/s reads, 9.6 GB/s writes, and 1.45 million IOPS for 4K random access. Endurance reaches 2,400 TBW, while a peak power draw of 6.4 W eliminates the need for a cooling solution.

Pricing remains undisclosed, but a 5‑year warranty backs the unit. The addition gives consumers a higher‑capacity mid‑range Gen 5 option without sacrificing speed or reliability.

KIOXIA’s move fills a gap in the Gen 5 market, offering a cost‑effective, high‑capacity SSD that could appeal to gamers and professionals alike.
