Kioxia Exceria Plus 2TB NVMe SSD Review (2026)
The Kioxia Exceria Plus 2TB is the range-topping capacity of this vertically integrated NVMe line, combining Kioxia's own controller with native BiCS5 TLC NAND for 3,400 MB/s reads and 800 TBW endurance.
Controller & Memory
The Exceria Plus 2TB uses Kioxia's TC58NC1201GST in-house controller with Toshiba BiCS5 96-layer 3D TLC NAND and a 2 GB DDR4 DRAM cache — the maximum DRAM configuration in the range. Kioxia's vertical integration (designing both the controller and manufacturing the NAND) gives them full control over the firmware and flash pairing, which can yield better consistency than third-party controller implementations.
Rated at 3,400 MB/s sequential reads and 3,200 MB/s sequential writes, the 2TB model matches the smaller capacities on peak speeds while offering substantially more endurance at 800 TBW. The larger SLC cache and more NAND die for parallel writes also make it the best-performing variant under sustained workloads. The drive is double-sided, with NAND on both faces of the M.2 2280 PCB.
At 2TB, the Exceria Plus targets users who need bulk NVMe storage for game libraries, video editing projects, or a combined OS-and-data drive. Direct competitors include the Samsung 970 EVO Plus 2TB and the WD Black SN750 2TB, both at higher price points.

Exceria Plus Performance & Benchmarks
The Exceria Plus 2TB is rated for 3,400 MB/s sequential reads and 3,200 MB/s sequential writes, with 680K random read IOPS and 620K random write IOPS. The 2TB model's larger SLC cache absorbs roughly 80–150 GB of burst writes at full speed before folding to TLC. Native TLC writes sustain around 2,000 MB/s — strong for PCIe 3.0. With more NAND die available for parallel operations, the 2TB model maintains higher throughput under mixed workloads than the 500GB and 1TB variants.

Verdict: Is the Exceria Plus Worth It in 2026?
The Kioxia Exceria Plus 2TB is a strong high-capacity PCIe 3.0 NVMe drive with 800 TBW endurance and the performance benefits of Kioxia's vertically integrated controller-and-NAND design. The 3,200 MB/s write speed and 2 GB DRAM cache make it well-suited for content creators and enthusiasts with large game libraries. The limitation is PCIe 3.0 — builders who want to populate a Gen4 M.2 slot should look at the Kioxia Exceria Pro or G2 instead. For PCIe 3.0 platforms or budget Gen4 builds where backward compatibility matters, the Exceria Plus 2TB is a reliable and well-priced option.
