SAMSUNG RAPID MODE TECHNOLOGY ACTIVATED!
RAPID stands for ‘Real-Time Accelerated Processing of IO Data’. We think the best way to start this portion of the report is to display the results of RAPID Mode Technology from the first time you start the system, once activated.

Samsung’s RAPID ModeTechnology is included in the newest release of Samsung Magician and presently works with the 840 EVO, although we will soon see a release to include the Samsung 840 Pro. RAPID Mode is a memory caching program that uses up to 1GB of your systems RAM and ‘analyzes a user’s application and data usage, optimizes the IO for Samsung SSDs accordingly and eliminates system performance bottlenecks.’ Specifically, RAPID Mode focuses on improving random performance with small file data and low queue depths (QD). In time, ‘hot’ or frequently used data is recognized and sequential performance is enhanced as well.
Activating RAPID Mode is simply a matter of pressing a button and it remains activated even through system shut down and restarts.
The best way to judge the performance of an SSD is through results that are as pure as possible. We don’t want to jade the true performance through caching and that is exactly why we have provided the initial results as we always do. As well, caching does not always get along with some benchmark programs as we see here with the ATTO result. Any thought whatsoever that we are reaching 3.8GB/s transfer speed is just unrealistic and the fact that this test does not provide consistently graduating performance is a giveaway.
