KIOXIA EXCERIA PRO NVMe Gen4 2TB SSD Review

Storage/SSD by stefan @ 2023-04-27

The EXCERIA PRO 2TB drive from KIOXIA, even if it does not often hit the rated performance numbers, it is quite speedy overall and should be fine for most applications/games. When stressed, the temperatures did climb up to about 74 degrees Celsius and at that moment the SLC cache got depleted too and we noted gradual drops in performance, to a minimum of about 500MB/s.

Drive Behavior during Continuous Write

To begin the second stage of the tests, we needed to fill the drive over 50% and we have done that by writing continuously to the drive to monitor its behavior. The IDLE temperature we have recorded was 41 degrees Celsius:

 

 

 

The transfer speed remained optimal after writing about 20GB to the drive:

 

 

 

The conditions remained similar even after writing about 205GB:

 

 

 

The temperature has raised at this moment to about 61 degrees Celsius:

 

 

 

The first performance dip we have observed after 220GB of data written:

 

 

 

The temperature continued to raise but remained at optimal levels:

 

 

 

The speed remained the same, between 950MB/s and 1.1GB/s for most of the time:

 

 

 

We have recorded a maximum temperature of 74 degrees Celsius:

 

 

 

In the last part of the test, the speed varied between 500 and 600MB/s:

 

 

 

 

 

 

With the SLC cache filled, we noted that the drive temperature dropped again a bit to around 67 degrees Celsius, but then climbed back up to 73 degrees Celsius:
