The SSD860 EVO supports Samsung’s RAPID technology. RAPID stands for Real-time Accelerated Processing of I/O Data and works by using a portion of the system’s memory as a fast cache for the drive. It’s accessed via the Magician management tool.
RAPID has a much more profound effect on read performance than writes as can be seen in the CrystalDiskMark results at both shallow and deep queue depths. Although the write performance gets a healthy boost, it’s nowhere near the levels of the read improvement.
In the PCMark 8 Storage test the effects of enabling the RAPID technology vary considerably. When testing the Adobe Photoshop Heavy, Photoshop Light and the Microsoft PowerPoint traces RAPID makes a huge difference and there’s a healthy rise in the Abobe Indesign, Microsoft Word and Excel performance figures as well. The rest of the test suites show not much improvement at all.
So the RAPID technology gives a really nice healthy boost to benchmark scores so it must improve things in real life … right?
Well for starters, the RAPID mode cache uses software that loads after the OS – so it has no effect on boot up times. As for program loading times, yes it makes a difference, saving some time (with the exception of Microsoft Access, where the time was slower with RAPID enabled) but we are talking milliseconds, so it is actually not noticeable at all.
