Pit, the chipset supports up to 2 volumes per array if you try to accelerate the RAID 0 volume, the system will need to create another RAID volume, and that will exceed the maximum amount of volumes supported. So, it cannot be accelerated.
Here is some additional information about Matrix RAID volumes
Thanks, sylvia_intel for your answer.
So if I understand correctly in SRT the ssd drive and the cached volume (RAID or single disk) are in some form of RAID relation and that's why caching Matrix is not possible. Matrix uses 2 volumes (by design) so no free "slot" left for SRT cache drive.
But what about Matrix RAID and SRT system coexisting on the same controller. For instance I have 3 platter based hard drives and the ssd drive. I'm setting up my system like this: 2 Hdds form Matrix RAID and the remaining 1 Hdd is cashed by the ssd drive. Will this work?
I'm asking because I have read somewhere that setting up any Matrix RAID in the system automatically disables the possibility of use the SRT even if the cached platter drive wouldn't be a part of the Matrix or even any other array. But I don't know if it's true and my buying decisions depend on that.
I did some testing using my new 256GB ssd drive and a bunch of 4 old hard drives (250GB each).
Obviously I cannot do this! I can create RAID-0 volume on the outer part of the array but after doing that, one should expect to be able to create RAID-1 volume on the remaining space. This is not possible! Create button disappears. I can only "Increase size" of the array. I'm not allowed to add the second volume to it.
As you can see I didn't even enable SRT yet (no black circle label on cached volume - RAID0 named "Cached"). The mere presence of the Cache enabled drive in the system (even without activating caching itself) appears to block the possibility to use any MatrixRaid in the system.
One could think. OK, so let hack a little and unplug SATA_Array_0000 with SRT enabled SSD and then create Matrix type of storage on those two 250GB hard drives. And after this plug the SSD again. Well... this is the result:
As you can see there is a Matrix drive present and accessible (SATA_Array-0001) , there is the ssd cache volume present (SATA_Array-0000) but the cached (RAID-0) volume became nonexistent. It is visible as two drives with exclamation warnings and status" Disabled" visible in the preboot rom summary screen.
And caching is disabled:
Is it normal?
Pit, the following are the system requirements for the Intel® Smart Response Technology. You will be able to see that it will work on a Single Hard Disk Drive (HDD) or multiple HDD’s in a single RAID volume only.
- Intel® Z68 Express Chipset-based desktop board
- Intel® Core™ Processor in the LGA 1155 package
- System BIOS with SATA mode set to RAID
- Intel Rapid Storage Technology software 10.5 version release or later
- Single Hard Disk Drive (HDD) or multiple HDD’s in a single RAID volume
- Solid State Drive (SSD) with a minimum capacity of 18.6GB
- Operating system: Microsoft Windows* Vista 32-bit Edition and 64-bit Edition, Microsoft Windows*
