The Kioxia Exceria Plus G4 is an internal solid-state drive (SSD) designed for general consumers, available in 1 terabyte (TB) and 2 TB versions. It is Kioxia’s first consumer SSD compatible with the PCIe Gen 5 interface, which promises faster data transfer speeds compared to previous generations. While it is not the fastest SSD in Kioxia’s lineup—its Pro G4 model offers higher speeds—the Exceria Plus G4 is noted for its relatively affordable price. The 1 TB version costs around 160 euros, and the 2 TB version is priced at approximately 240 euros, which is considered reasonable given the current state of the SSD market. The Exceria Plus G4 features a certified endurance of 1200 terabytes written (TBW) and comes with a five-year warranty. In testing, it achieved an average write speed of 3715 megabytes per second (Mo/s), though it lags behind high-end models like the Renegade Fury G5 from Kingston. On the CrystalDiskMark benchmark, it delivered average sequential read speeds of 10,397 Mo/s and write speeds of 8,752 Mo/s, which aligns with expectations. Its performance is nearly identical to the MP700 Elite from Corsair, likely due to the shared controller and NAND flash chips. The Exceria Plus G4 uses a Phison E31T controller and 218-layer 3D TLC NAND flash chips. While it meets the specifications set by Kioxia, it does not fully exploit the potential of the PCIe Gen 5 interface, which is capable of much higher speeds. In terms of input/output operations per second (IOPS), it performs consistently in random 4K tests, matching more expensive models like the Samsung 9100 Pro and WD Black SN8100. However, in real-world scenarios like copying a 27 GB file, it averaged 3503 Mo/s for reading and 2160 Mo/s for writing, which is still within expected performance ranges. Despite its effective performance, the Exceria Plus G4 is considered somewhat conservative in utilizing the PCIe Gen 5 interface. It is a solid entry-level option, particularly when compared to more expensive models from Samsung and SanDisk that achieve better performance with the same interface. At a similar price point, it outperforms the recent Samsung 990. During stress tests, the drive reached a maximum temperature of 81 degrees Celsius, which is manageable but should be handled with care. The benchmarks were conducted using a heat sink from an Asus ROG Crosshair X670E motherboard to ensure accurate comparisons. Overall, the Exceria Plus G4 is a reliable and effective storage solution, even if it doesn’t push the boundaries of its technology.
