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.
Here the Intel 600P ends up dead last with an average speed of 285MB/s write. The SATA based Samsung 850 EVO even out-performs the Intel 600P in pure write performance. Let’s see how well power consumption is regulated next.
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.
During idle, the Intel 600P consumes under 1W. This is the lowest, best result we have seen yet. Compared to SATA though, this result is much higher.
POWER EFFICIENCY
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 write test, it delivered 74MB/s per Watt of energy used. Overall, this result places the Intel 600P dead last, yet again. If you are looking for the most energy-efficient drive under load, there are better options out there.
Passed my first test-At least 8K-IOPS-QD1.
Failed my second-Must write 200+ after buffer
can’t have it bottleneck my spinning rust.
Write speed shocked me for a 500 size drive
those speeds you expect on a 120 size drive.
And why the SLC cache so small???????
The ATTO results make sense as the 600p doesn’t have a controller that supports direct to die algorithm to relieve the bottle neck that occurs once the SLC cache is full. That being said very few program reads, go above 128K in windows. So, everything past that is just large file transfer, and really inconsequential in day to day compute performance outside of OS install.
