The KIOXIA SSD Utility includes a quick performance test, that gave around 6.95GB/sec reading and 6.02GB/sec writing performance

The Samsung Magician v7.0 offers a quick look at the drive's performance with around 7.42GB/sec reading and 6.4GB/sec writing performance.

The AJA Test System shows a quick overview of the drive's reading/writing speed, having around 5.75GB/sec writing and around 5.80GB/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 7825 points.

Passing the IOMeter test, with our custom configuration, the drive performed well with 101633.60 points, The max I/O response time is around 5.285ms 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.

The next step was to find out if the drive has any issues with a much bigger file and its writing speed. We used a single 286GB file of data from the Samsung 980Pro 1TB to the KIOXIA Exceria Pro 2TB NVME SSD. The drive, due to its onboard DRAM, had excellent performance and managed to write the 286GB file in 53 seconds, on par with other NVME drives. The performance was stable and around 3.8GB/sec

The drive, as we mentioned earlier, does produce a lot of heat, due to the fast PCIe Gen 4 protocol, and with the Asus motherboard passive heatsink reached 74 Celsius, while "normal" running temperatures were around 51 Celsius.

With the be quiet! MC1 Pro NVME SSD, we got lower working temperatures of up to 68 Celsius.
