Hey guys,
I recently got a GA-P55-UD for my backup PC and since I was rebuilding it and had two 120 GB SATA SSDs lying around, I decided to to run them in Raid 0, because 1) 120 GB is not a lot by itelf nowadays 2) questionable performance gains 3) they're not worth much.
It was only afterwards that I it says that the RAID BIOS only supports HDDs, but I had no problem installing and running windows. However, when I wanted to move some large files from the HDDs (also in RAID 0) I noticed that the SSDs are getting bottlenecked and the response time of the drives sometimes goes over 4-5K ms, which is absurd. Write tests were now tanking in speed compared to previously (I measured it after installing Windows). On further inspection I noticed that the drives are "fragmented" (unoptimised), but the option to optimise them is grayed out in Windows Defragment and Optimise service window.
I tried to manually optmise them with Powershell and got an error saying that the drives don't support that command. So it seems to me that because the RAID only supports HDDs, windows can not send TRIM commands to them, despite the drives appearing as SSDs in Task Manager, etc.
Before you ask, yes, I am running the RAID on the Intel chipset, not the sketchy one.
I looked across the web, but it seems no one ever has tried to do this, so there anything I can do, or do I have to rebuild the whole setup with only one SSD?
