Corsair Neutron NX500 NVMe SSD Review (400GB)


We also wanted to see how performance was in a real-world use when transferring large files to the SSD. For this test, we are going to simply stress write performance by transferring over a 30GB folder of movies off of a 512GB Samsung 950 Pro to the test SSDs and time how long it takes. Once complete we can calculate the average speed.

When testing in real world file transfer, the NX500 did very well. With an average speed of 1258MB/s, it ties with the OCZ RD400 for 3rd place.


For our power consumption testing, we have the drive connected to the system as a secondary drive. To record the wattage, we are now utilizing a Quarch Technology Programmable Power Module. It allows us to accurately measure power consumption over time and is flexible enough to allow us to test any SSD that comes our way.

Quarch Technology Power Module Angle

Our power analysis may change as time goes on, but for now, we are looking at just a few metrics with the main goal of measuring our results against the manufacturer’s ratings. Because most consumer systems are at idle for about 80% of the time, idle power consumption is an important measure to look at when understanding the efficiency of a drive.

During idle, the NX500 is rated for just 0.5W. During our testing, however, it averaged just over 1W. This, however, is less than the MP500.


Finally, we wanted to post up a graph of the power efficiency of the SSDs in comparison. We are looking at MB/s per Watt in this graph. The higher the result, the better.

During our File Transfer Efficiency metric, the Corsair NX500 came in the middle of the pack. With an average of 253MB/s per watt of usage, it shows to be less efficient than the MP500.
