TSSDR TEST BENCH AND PROTOCOL
For today’s testing we will be using our current test system that has been optimized with our SSD Optimization Guide. To see the best performance possible the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch. We even provide links to most of the benchmarks used in the report.
We would love to thank those who jumped in specifically to help the cause. Key contributors to this build are our friends at ASRock for the motherboard and CPU and be quiet! for the PSU and cooling fans. Also, a big thank you to Thermaltake for the case and Kingston for the RAM. We have detailed all components in the table below and they are all linked should you wish to make a duplicate of our system as so many seem to do, or check out the price of any single component. As always, we appreciate your support in any purchase through our links!
This Test Bench build was the result of some great relationships and purchase; our appreciation goes to the mentioned manufacturers for their support in our project. All of the components we use for testing and evaluation can be easily purchased at a relatively affordable price. The links provided below can assist in pricing, as well as availability for those of you who may find interest in our equipment.

To test RAPID the software we will be using for today’s analysis include Samsung Magician, BootTimer, PassMark AppTimer, and PCMark 8. We prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.
To start off our testing we chose to use Samsung Magician’s built in benchmarking tool to compare the performance of the drives. The darker blue bars are the results before RAPID was enabled on the system. The light blue bars are the results after RAPID was enabled.
Based on this synthetic test, performance seems to be night and day when comparing the drive with synthetic tests. Random read IOPS shot up to over 2x and write IOPS increased by 50%. Sequential reads and writes improved to 10-11x. From these results, impressive is an understatement. Now, let’s move forward to startup and application load times.
In order to test the startup time we used a simple program called BootTimer. BootTimer gave us consistent results on how long each system boot took over the course of testing.
Numbers don’t lie. Over the course of 5 system reboots, enabling RAPID results in slower boot time…while only slightly, it does have a detrimental effect.
For testing application load times we used PassMark AppTimer. AppTimer can measure the time it takes to open an application and automatically run multiple iterations of opening the application one after another. It then creates a log file with the results. Each application was launched for 5 iterations. Below are the results from launching popular software applications.
Based on these results it seems like Window’s default caching system already caches the programs into the cache after they are first launched. There is essentially no difference in application load time whether RAPID mode is enabled or not. So, we then rebooted the system and tested again, RAPID mode is supposed to retain the previously cached files after the system is rebooted, unlike the default Windows behavior which is to flush them.
We also noted when testing that RAPID will work 45 seconds after the system is booted and waited thus to begin testing again. This delay for RAPID mode can be seen in the memory tab of the task manager under Non-paged pool. Without RAPID the value is around 125MB in our system. Once RAPID begins working, the value changes to 1.3GB.
After testing multiple times, the results above bring us to the conclusion that RAPID does not in fact speed up application load times. Windows already does a good job at caching these files itself. However, one thing to notes is that while Windows already caches program files, Samsung’s algorithm is supposed to do it more aggressively to frequently used files. Let’s put that to the test.
For this we re-ran the iterations over 3 system reboots to ensure RAPID would have enough time to cache the files. The final reboot’s results are what are displayed. We can see that RAPID was able to load the Photoshop file initially after reboot a little faster than when RAPID is disabled, however after the first load time, it actually takes longer for consecutive load times.
Overall, the averages were practically the same. We are not seeing this claimed “almost 1.8x performance gains at Windows start up and application loading.” This is a bit of a disappointment as that is what they are essentially marketing RAPID to do. Startup times are slower and application load times were unaffected. Now, there is still more testing left, hopefully RAM caching will help in our next segment. Let’s move on to running light and heavy workloads to see if it really does increase performance in real world tasks.
