Kioxia Exceria Plus G4 2 TB Review – Energy-Efficient PCIe Gen 5

Introduction

The Kioxia brand was established around 2018/2019, after Toshiba sold its SSD and memory branch “Toshiba Memory.” The company now produces flash memory for its own products, but also WD and SanDisk. Part of the original Toshiba SSD business was formed in 2014, when Toshiba bought the famous OCZ brand. Kioxia later acquired the SSD maker Lite-On. Unfortunately, first party Kioxia SSD products are not available in the United States.

In today’s review we are taking a look at the Kioxia Exceria Plus G4, which, as the name suggests is the fourth generation of the company’s “Exceria Plus” solid-state-drive. What’s new with the G4 is that it is Kioxia’s first consumer SSD that introduces support for the PCI-Express Gen 5 interface. We reviewed the Exceria Plus G3 last year, the new G4 uses a Phison E31T controller instead of the E21 on the G3, and the NAND flash is Kioxia’s 218-layer 3D TLC (vs 112-layer 3D TLC on the G3). This E31T+218L TLC combination is used on other drives, too, like the Corsair MP700 Elite, PNY CS2150 and MSI Spatium M560.

The Kioxia Exceria Plus G4 is available in capacities of 1 TB and 2 TB. While Kioxia doesn’t sell these drives in the States, pricing in Europe is €112 for the 1 TB model and €190 for the 2 TB variant, including 20% VAT, which we converted to $100 and $170 respectively. Endurance for these models is set to 600 TBW and 1200 TBW, respectively. Kioxia offers a five-year warranty with the Exceria Plus G4.
