Kioxia EXCERIA PLUS G3 2TB SSD
3. Tests
The AJA Test System shows a quick overview of the drive's reading/writing speed, having around 3.85GB/sec writing and around 3.69GB/sec reading.
Passing to a more well-known benchmark, the ATTO Disk Benchmark shows the performance with various file sizes from 0.5Kb, 1Kb, and 2Kb up to 8192MB file sizes. The drive did perform a little slower than its specifications but this was seen with many recent PCI-e Gen4 NVME drives.

Passing to the newest ATTO Disk Benchmark 4.01.0F1, performance was better, however, after a point, we saw a writing performance drop, which indicates a possible thermal throttle situation (Asus motherboard stock passive cooler).

Getting into AS SSD Benchmark software, the drive got an average score of 7104 points.
Passing the IOMeter test, with our custom configuration, the drive performed well on average with 43046.89 points, whereas with the KIOXIA EXCERIA PRO, we got around 101633.60 points. The max I/O response time is around 6.7196ms which is a great score.
Passing to real-life writing tests now, we used a Samsung 980Pro 1TB drive as the source to test the writing abilities of the 2TB drive. The first test was to try to write a single file of 44GB data from the Samsung 980Pro 1TB to the KIOXIA drive. The writing performance was very good and stable around 3.8GB/sec during the whole writing process. We didn't have any serious drop in writing speed. All tests were done with the TerraCopy software.
whereas with the FastCopy software, writing performance was slightly better with around 3.99GB/sec writing performance.
The next step was to find out if the drive had any issues with a much bigger file and its writing speed. We used a single 208GB file of data from the Samsung 980Pro 1TB to the KIOXIA 2TB NVME SSD. The drive, despite using the host memory to accelerate the writing/reading process did perform very well with an average of 3.98GB/sec writing performance, meaning didn't slow down its writing performance, even with such a big single drive.
The drive with the Asus stock motherboard NVME passive heatsink, at idle state did have around 56 Celsius
, while at full load did introduce up to 66 Celsius, which is very good according to what KIOXIA reports at their own SSD Utility
