REAL WORLD FILE TRANSFER
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 250GB Samsung 960 EVO to the test SSDs and time how long it takes. Once complete we can calculate the average speed.
Transfering our 30GB of test files over to the MP300 resulted in an average write rate of 737MB/s, tying it with the MyDigitalSSD SBX. Also, it is worth a note that it delivered better performance in this test than the Intel SSD 760p and again, the Samsung 960 EVO at the same capacity.
POWER CONSUMPTION
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.
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.
First up we have our results with Active State Power Management disabled. The MP300 has a decent idle draw when power savings features are disabled. It came in just behind the MyDigtialSSD SBX’s, which are the best here.
In the chart above, with ASPM enabled, we can see that it consumes even less power, but there is still room for improvement. Here it drew 0.348W at idle.
POWER EFFICIENCY
Finally, we wanted to post up a graph of the power efficiency of the SSDs in write transfers. We are looking at MB/s per Watt in this graph. The higher the result, the better.
The MP300 delivered decent efficiency during the transfer, 260MB/s per watt. This is not quite as efficient as the MyDigitalSSD SBX, but better than some of the higher performance options in the market.
