Real-World Performance Testing
Game Load Time
Moving into the application portion of this review we get see what our synthetic workload analysis means for your experience with real software. Most consumer applications use random data reads at low queue depths. The 860 QVO has a difficult time with this workload, and it will be interesting to see how that carries over to applications.
The game load-time test comes to us from Final Fantasy: Stormblood. The two QVO SSDs complete the levels in just over 18 seconds. The loads take nearly two seconds longer than the 1TB 860 EVO, but over 3.3 seconds more than the 1TB MX500.
PCMark 8 Total Storage Bandwidth
The PCMark 8 Storage Bandwidth test uses nine common applications to perform ten tests. We combine the results into a single, easy to digest, throughput summary to make comparing products simple.
The two 860 QVO SSDs trail the comparison products. Here we added the 850 EVO and 860 Pro to see the full span of popular Samsung SATA products in use today. The important take away from this test is the 1TB 860 EVO delivers just over 300 MB/s, but the QVO SSDs only manage to reach two-thirds of that mark.
PCMark 8 Extended Storage Test
The PCMark 8 Extended Storage Test gives us a better understanding of the two QVO SSDs under heavy workloads. It also shows how these drives have recover from heavy use. Both QVO SSDS show very high service times under heavy use. Under typical use, you will never see the extreme latency, but at the same time, you should be mindful when first installing programs on the QVO series. Give them some time to recover between installing games back to back.
SYSmark 2014 SE System Responsiveness and Power Tests
The responsiveness test that is part of the SYSmark 2014 suite uses common software like Word, Excel, WinZip and popular Adobe software to run through a workday in the office. The responsiveness portion is a direct measurement of the user experience taken from the latency of applications rather than a simple throughput perspective.
The 860 QVO SSDs deliver strong office activity performance, but these drives are not replacements for the 860 branded SSDs. The 4TB model shows an impressive performance increase over the 1TB model that trails all of the other drives in this chart (but matches the aging Toshiba VX500).
Notebook Battery Life
In the previous section, we observed high efficiency with the 860 QVO SSDs but didn't comment on it. We wanted to combine the two power tests together for analysis. The QVO SSDs didn't fair as well in our notebook test using BAPCo's MobileMark suite in our Lenovo Y700-17. The difference between these two tests that run on the same notebook is the power management settings between wall power and battery power. It's rare to see a drive sip power in the first test, and then not perform well in the second.
