With Magician V4.2 (available publicly soon) the 840 EVO is able to boost beyond 500MB/s using the SATA 6GB/s interface. Samsung claim that this feature can push transfer speeds even past 1GB. In short, RAPID mode takes advantage of dynamic disk caching technology. This makes use of left over CPU and RAM resources in order to boost the performance of the SSD.

To demonstrate this feature we will show performance results for read/write transfer speeds with and without the RAPID mode enabled within Magician V4.2. (To take full advantage of this feature just install Magician V4.2+ and click RAPID mode – reboot required).


As you can see below, the performance gains on offer by using RAPID mode are rather significant. We tested a range of different benchmarks to simulate different usage and to reveal how flexible this feature really is.
