Problems with SSD and Raid 0 Array. Raid 0 array is recognized by Intel RST but is unallocated under disk management . The option seems to be to task it as "new striped volume" but it will not allow it. "next" in the second screen under disk management "new striped volume" is whited out. Unsure of where to go from here.

For all practical purposes, Windows has not a clue whether a raid volume set up on a hardware raid controller, like the motherboards controller or an add in card, is raid or not. The controller takes care of this and the volume is presented to windows as simply a single large drive. Proceed as if your newly created raid volume is a single drive. What you are seeing are the options windows has built in to create software configured and controlled raid volumes under windows, which all it really does is a fancy form of drive spanning.

In Disk Management you want to right click and select "New Volume/Partition". As long as the RAID 0 is already setup it should show as one large unallocated HDD in Disk Management.

If you have more than 2TB, make sure to select GPT as the formatting type as it will make it one partition. If you have say 4TB total space (two 2TB HDDs) if you choose MBR, it will make it two partitions, one will be 2TB the other will be the rest which is about 1.6TB. If you select GPT you can have one 3.6TB partition.

He is not using the built in Windows system, he stated it shows in RST. He is using the built in Intel RAID firmware, which is what I have.

Did I suggest he was using software raid? I dont believe I did.

Thanks for the info. Things went as you said they would . The raid array did show up and was available. However having installed Win 8.1 on a seagate 600 256 GB drive after I selected GBR to keep all three 1 GB drives as a single drive in the array I immediately realized I had made a mistake. It performed like a ton of slush. Windows had been installed under MBR so with a GBR array things did not go well. I should have kept the volumes below 2TB and saved myself a lot of trouble. I re-installed to the 256 GB SSD and just used 2 wd black 1TB drives in the raid 0 array. The third drive turned out to be defective so an RMA is in order leaving me with only 2 drives. I am pleased with the performance anyway. To clarify I used the intel rst option rom to make the array. I installed Win. 8.1 to the SSD without the drives attached. Attached after installation and allocated through disk management. It is an Asus z87-plus with a i7-4770k 3.5GHZ cpu w/ 32 gig. r skill trident x ram , a power color 7870 graphics card, seagate 600 256 SSD, 2 WD Black 1TB drives in raid 0 (128k stripe ).
Thanks,

Glad to hear that your system is up and running. I have 2 2TB Seagate HDDs in a RAID 0 and I use the BIOS to set them up. Love RAID 0 for games and data but I keep most important stuff backed up.

Enjoy your build.
