    Intel Rapid Start & Smart Response minimum SSD requirements

    halo9

      Hi,

       

      I just have a few questions regarding the two technologies mentioned and the minimum SSD size required to run each one on a system. A bit of background, I bought a Dell XPS 15 (9530) recently and it is advertised to run both Intel technologies together. It comes with a 1TB HDD and 32GB SSD to act as cache.

       

      I have read all of Intel's literature on the two techs and it states that Intel Smart Response requires a minimum of 18.6GB to run and also that Intel Rapid Start requires a minimum amount of SSD space equal to the amount of RAM. The Dell system comes with 16GB of RAM. So in total to run both technologies together on this system I would need an SSD with a minimum of 34.6GB. Dell partition the SSD with 8GB for for the Rapid Start partition and 22GB for the Smart Response partition.

       

      I have contacted Dell to clarify this as the system does not start very quick when resuming making me think the Rapid start feature is not working due to the partition only being half the size of the amount of RAM. The response I got was:

       

      "HDD + 32GB mSATA config can support both Intel Rapid Start and Intel Smart Response.  After the iRST driver ver 12.7, it needs min 12GB cache area.   Smart Response does not require dedicated cache just for itself. Also Intel Rapid Start requires only 8GB. It does not have to be the same amount of main memory. Thus 32GB is enough to support both function."

       

      I looked up the release notes for the iRST release which contains the 12.7 orom (Intel´┐Ż Matrix Storage Technology) and it states at point 4 that "

      4.    Support for 16GB minimum cache requirement for SRT “Dual Drive SSD cache” will not be enabled in the RST 12.8 release and is targeted for RST 13.0 release", which is not even out yet.

       

      So is Dell telling me the truth? Do these two techs run on the minimum specs Dell have provided or do they need the minimum specs that Intel specifies to work properly. i.e. According to Dell it is 20GB minimum for both and Intel states 34.6GB. I'm chasing this up as the performance falls a bit short for a laptop that cost AU$2500 and I want to be sure it is not a OEM set up flaw.

       

      Thank you everyone for your help.

          Hi halo9,

           

          I am sorry you are having problems with the system but let me help you.

           

          Based on your description I have to point something you said and that where the issue lies.

           

          Intel® Rapid Storage Technology requires 18.5 GB as minimum capacity of a SSD to cache the system and the Intel® Rapid Start Technology requires a hibernation partition with equal to or larger than the amount of system memory. This means that the total should be 34.5 GB of the SSD while your system has a SSD with 32 GB capacity.

           

          I am sure the system can work with both technologies when having the correct configuration but I regret to say that with your current configuration is not possible to use both.

           

          PD: Great nickname by the way!

            Thanks Kevin.

             

            Is there no way that there would be hidden features in the IRST driver available to OEM's to change minimum requirements?

             

            I'd guess if there was anything changeable in the minimum specs (like Dell claim) it would be documented in the official Intel documentation for the driver release and would be available to everyone.

             

            I'm just struggling to understand why Dell would state the IRST driver from 12.7 only requires 12GB cache for Rapid Storage and only 8GB (to store 16GB or RAM) for the Rapid Start feature. Here is their response quoted;

             

            HDD + 32GB mSATA config can support both Intel Rapid Start and Intel Smart Response.

            After the iRST driver ver 12.7, it needs min 12GB cache area.

            Smart Response does not require dedicated cache just for itself.

            Also Intel Rapid Start requires only 8GB. It does not have to be the same amount of main memory.

            Thus 32GB is enough to support both function.

             

             

            Thanks again.

              I completely understand this is frustrating for you and I am sorry for that. 

               

              From our side the driver/ Interface do not provide an option to change this. If you are using the OEM driver version, sometimes they change or manipulate the interface but that information is not available for us.

              I can confirm that what I mentioned before and you also said is necessary to have both technologies up and running.
