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. For reference, we have included both a 2.5″ and 3.5″ WD Blue HDD.
In this test, we went it knowing that the TL100 wasn’t going to do so well, especially after seeing our PCMark 8 results. The 120GB model out performs the BX200, our previous worse performer in this test, but the 240GB model took the BX200’s crown and averaged 90MB/s…which is just barely faster than our 500GB WD Blue laptop HDD. Compared to a standard 3.5″ drive, both SSDs were defeated quite easily in this task as well. Overall, this test supports the marketing claims that this drive is designed as an entry level SSD for use cases where heavy writes are not utilized on a daily basis.
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.
Looking at the idle power consumption results we see that they are better than what OCZ has listed on their specifications sheet. Both models idle at about 0.37W – 0.38W. This however, is much higher than many of the newer SSDs that have sub 100mW idle results.
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.
Finally, looking at the efficiency, we can see that just as in our other tests, the results are not that great. The TL100’s slow write speed results in very low efficiency even though the wattage consumed was very low with both drives consuming 1.2-1.3W average.
