Kioxia has announced a new 4TB capacity option for its EXCERIA G3 SSD – VC10 series, expanding the company's PCIe 5.0 storage lineup with a higher-capacity model aimed at gamers, content creators, and AI-focused workloads. The new drive is based on Kioxia's eighth-generation BiCS FLASH 3D NAND technology and joins the existing 1TB and 2TB variants already available in the EXCERIA G3 family. According to the company, the additional capacity option is designed to address growing storage requirements for modern gaming systems, AI applications, and high-capacity desktop environments. Performance specifications remain unchanged across the lineup, with the EXCERIA G3 series offering sequential read speeds of up to 10,000 MB/s and sequential write speeds of up to 9,600 MB/s through its PCIe 5.0 x4 interface.

Unlike the lower-capacity models, the new 4TB version utilizes 2 Tb quad-level cell (QLC) NAND flash memory. The use of higher-density flash enables the larger capacity while helping keep manufacturing costs under control, allowing Kioxia to target the mainstream PCIe 5.0 market segment.

As PCIe 5.0 SSD adoption continues to grow, higher-capacity models are becoming increasingly important for users running large game libraries, local AI models, virtual machines, and content creation workloads that can quickly consume terabytes of storage.

Kioxia says the EXCERIA G3 4TB SSD will become available through major retail and e-commerce channels by the end of June. Pricing has not yet been disclosed.

The launch further strengthens Kioxia's PCIe 5.0 portfolio, giving buyers an entry-level Gen5 SSD option with capacities now ranging from 1TB to 4TB.
