The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:
- Windows Defender In Use
- Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
- Importing digital photos into Windows Photo Gallery
- Starting the Vista Operating System
- Home Video editing with Movie Maker which can be very time consuming
- Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as Xbox
- Cataloging a music library
- Starting applications
PCMARK VANTAGE RESULTS
In PCMark Vantage, both capacities performed very well. The Samsung 850 EVO 120GB (results pictured left) achieved a Total Score of 88,025 points with a high transfer speed of 454.55MB/s during the Windows Media Center phase. The Samsung 850 EVO 500GB achieved a Total Score of 87,456 points with a high transfer speed of 457.66MB/s when testing Windows Vista startup. The application loading benchmark results was the lowest with both drives reaching 360.64MB/s and 350.98MB/s respectively.
Looking back at our 850 Pro review, the 120GB 850 EVO has actually surpassed the 850 Pro at the same capacity in PCMark Vantage. TurboWrite is proving to be quite impressive.
As a bit of comparison as to how the 850 fares, we have maintained a PCMark Vantage Heirarchy Chart, which for the most part has been consistent in its representation of upper tier SSD. This chart is based solely on PCMark Vantage Total Point scoring and no other benchmarks but, as we can see, the 850 EVO fares very well against even the best!
For our last benchmark, we have decided to use PCMark 8 Extended Storage Workload in order to determine steady state throughput of the Samsung 850 Pro. This software is the longest in our battery of tests and takes just under 18 hours per SSD. As this is a specialized component of PCMark 8 Professional, its final result is void of any colorful graphs or charts typical of the normal online results and deciphering the resulting excel file into an easily understood result takes several more hours.
There are 18 phases of testing throughout the entire run, 8 runs of the Degradation Phase, 5 runs of the Steady State Phase and 5 runs of the Recovery Phase. In each phase, several performance tests are run of 10 different software programs; Adobe After Effects, Illustrator, InDesign, Photoshop Heavy and Photoshop Light, Microsoft Excel, PowerPoint and Word, as well as Battlefield 3 and World of Warcraft to cover the gaming element.
- PRECONDITIONING -The entire SSD is filled twice sequentially with random data of a 128KB file size. The second run accounts for overprovisioning that would have escaped the first;
- DEGRADATION PHASE – The SSD is hit with random writes of between 4KB and 1MB for 10 minutes and then a single pass performance test is done of each application. The cycle is repeated 8 times, and with each time, the duration of random writes increases by 5 minutes;
- STEADY STATE PHASE – The drive is hit with random writes of between 4KB and 1MB for 45 minutes before each application is put through a performance test. This process is repeated 5 times;
- RECOVERY PHASE – The SSD is allowed to idle for 5 minutes before and between performance tests of all applications. This is repeated 5 times which accounts for garbage collection; and
- CLEANUP – The entire SSD is written with zero data at a write size of 128KB
Now, after a run of PC Mark 8’s consistency test, we can see that the results are definitely that of a client SSD. We tested only the 120GB model as the 500GB model would have taken too long to test. Throughout the entire degrade and steady state stages the performance for each test was roughly the same. The lowest results in the degrade/steady states were around 25MB/s during the Photoshop Heavy steady states. The highest came in the gaming benches for BF3 and WOW, averaging just under 200MB/s. Overall its degraded/steady state performance averaged out to around 70MB/s.
It wasn’t until the recovery stage that the 850 EVO was able to run at a faster pace. Photoshop Light reached a nice boost up to over 400MB/s and Photoshop Heavy hovered around265MB/s. The lowest result in the finally recovery states was about 155MB/s from Illustrator. Quite frankly, for the EVO to pull even this off in PCMark 8 says quite a bit about the caliber of this SSD.
