Rapid Mode on SSD

[𝔇ave]

How many of you enable it? also are there any drawbacks or benefits when it comes to gaming?

cheers :)

Rapid mode is simply a glorified RAM cache for SATA SSDs.

It involves RAM caching correct? Uses RAM as buffer cache for your Samsung NVME or SATA SSD. Honestly, I would probably leave it alone and not enable it because by the description of it, it seems like it would fragment your RAM whil it is in use.

ok thanks guys :) the drive performs really well as it is so i guess i dont need rapid mode.

how can you fragment your RAM? besides for a volatile memory it wouldnt even matter... and the way RAM works as it doesnt work like a HDD it wouldnt even matter if it is theoretically possible.

Rapid mode actually makes a SSD really fast. I load in games faster with RAM caching then Omega does witha NVMe Samsung 960 Evo...

so tacoshy i have only 16gb of ram and im happy with the standard performance of my ssd.been using a hdd for so long...assuming rapid mode reserves or uses system memory would the extra speed be worth the loss of system memory however small it would be?

Ok sorry for the late awnser but I wanted to took the time to run some Benchmarks for you. Please be aware that you proberly have a hard time to copy those result as you do not have the RAM capacity to pull it off too.

Using the Rapid Mode will use DRAM but only left over DRAM. SO DRAM that is not required for the PC. If your PC needs more DRAM Samsung Magician going to give instantly the RAM back and will cache slwoer then of course with less ammount of RAM to use but therefor you also see now downside on your normal tasks.

Well this is a generic test and of course the stuff has to be loaded from the SSD in the cache first which may take a few seconds but afterward it will be faster. Of course not everything like here going to be that much faster but you get the picture. Its faster with Rapid Mode ON then OFF.


PS: BTW -> You can't use Rapid Mode on a NVMe SSD...

You dont need rapid mode on NVME because it is already faster. Support for rapid mode is not on the 950pro or the 960pro.

There is no Rapid Mode support for any NVME SSD.

Is your M.2 SATA or PCIe?

You are Microsoft and Cisco Certified, you should already know just by looking at the make and model.

I asked this because if it is SATA, you won't be able to do it. If it is PCIe however, you can.

It's the other way around.

For SATA M.2 drives you can enable Rapid Mode, for NVME drives you can not.

your own question: have you ever read your own link? its just describing the normal usage of RAM files are splite and randomly placed and it doesnt matter since the RAM isnt a harddisk that needs the files in block next to each other as the ram doesnt have a spinning disk with a read arm that would take then longer to hit the files...

Well I am glad to learn something new then.
