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 512GB Samsung 950 Pro to the test SSDs and time how long it takes. Once complete we can calculate the average speed.
In this test, the BPX averaged a transfer speed of 1208MB/s, which is the same as the Hellfire and MP500.
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.
Again, during idle, the BPX’s result of 1.16W is nearly identical to that of the Patriot Hellfire and Corsair Force 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.
This is where the results surprise us a little bit. While it averaged the same bandwidth in our write test, it shows to be the least efficient 480GB E7 powered SSD we have tested. Still, however, its result is very good.
