    This isn't software RAID. That would be a RAID array defined through Windows DIsk Management, e.g.

    These RAID arrays are defined by the Intel chipset hardware and exist before any software is loaded. You can define them in the UEFI. However, they do get a bit of assist from the OS driver for certain features. In some ways it's a bit of a hybrid but they're solid and OS independent. They do not have a separate CPU supporting them like a PCI card-hosted array, but are still basically hardware-level arrays.

    This is still a software RAID, as your CPU does the work, the OS requires drivers,, and the disks must contain metadata in order to function properly.
    Also known as FakeRAID. It's actually more unreliable than a RAID defined by the OS or a RAID built into the filesystem.

    Not hardware level in the slightest, The firmware only defines the RAID, without software to do the work, it does nothing more than write a small amount of data at the end of the disk.

    So you really think there's no basic difference with a RAID array defined by the OS. OK, we can agree to disagree. I have had my RAID 0 go through dozens of BSODs without problems even though the OS occasionally gets shot, and the same array with the same disks if defined in my Areca 1882 PCI controller is noticeably slower. I'd say these arrays (however you want to designate them) are well worth every penny . BTW, I had no problems with my Win 10 upgrade on the RAID 0 array. I am using the latest Intel rev.

    I have also had no issues with Intel's raid (be it defined software, hybrid, hardware or what ever) and have been using it in several flavours for as long as I can remember. I have upgraded to W10 on two Intel based machines with raid. One an old 945 motherboard with a raid 1 and one with a Z77 with a raid 10 array both for data storage only. The OS is on a non raid drive, Seagate 500GB on the 945 and Samsung 128GB SSD on the Z77. W10 loaded on both without error but the Z77 machine developed file write errors and had the be "downgraded" back to W7. The old 945 still plods along without errors. The Z77 machine I forced an upgrade but the 945 upgraded naturally. My conclusion from this and what I read around the subject is that W10 is not yet fully compatible with raid. It will be interesting to see if the Z77 is offered W10 "naturally" later on. I have also seen that small SSD's (less than 256GB) can also have some issues around system restore which corrupts the system volume inf. mirroring the raid file corruption problem, so my Z77 could have been hit with a double issue. It may also be that when W10 rearranges the partitions to give a hidden restore volume it confuses the raid controller. Anyway good old Scan Disk resolves the file errors when W7 is back on.

    Well, both my system RAID 0 and data Raid 10 are doing fine with the latest Win 10 compatible Intel RST. I believe there is a problem with RAID cache enabled. I do have cache mode off but they run just as fast.

    Well i have some issues here and some resolutions after upgrading to Windows 10, first off my system is

    Asus x58 ROG formula 3
    2xwd black drives Raid 0
    latest Raid Rom offered by manufacturer is 10.5.0.1034
    After Win 10 started shooting BSOD's I modded Bios Raid ROM to v11.6.0.1702 <reason being it is the latest ROM supported by this intel chipset and offers trim support for SSD if i decide to upgrade, the Upgraded ROM did not solve the problem though>

    Ok so Windows 10 installed on the driver i was running in windows 7, 11.6.0.1030 and after windows 10 did so it automatically upgraded my driver to 13.2.0.1022 windows10inbox<disabled automatic driver update since then>. I did not get any BSOD at the time but i tried to open RST manager software and got a application Error windows failed to load.

    My first mistake was trying to upgrade to the latest 14.xxxx driver resulted in BSOD on windows boot. Then i decided to modify my Raid Rom from a recommendation someone made to me and tried the 11.7xxx Rste driver. The problem i am having with BSOD's now is directly related to the Raid manager software, if you are able to get in the O.S. and remove the software from add/remove programs. I think a good number of you will stop getting BSOD and the driver will function fine without it as long as you do not have an older chipset like mine which does not support the latest 13-14.xxxx RSTe drivers.

    After i realized the Raid software was causing my BSOD's i downgraded back to the original driver. I ran Benchmarks on each driver that was stable without the RST software and found my original driver gave me the best result with speed/consistency and the 13.2 windows inbox gave me the worst results.

    I would like to get my RST software to actually work, i have recently Reinstalled my Framework 3.5 in hopes the problem lies there. I have yet to try and reinstall my RST software, I will do so later when i am feeling Patient and report back.

    Have you tried 14.5.0.1081 with RAID cache off?

    It is still software raid in that striping and parity are done by windows driver software. In hardware raid,that is done by the hardware controller.

    What distinguishes it from, say, Windows raid, is that it is supported by Intel in the chipset and bios driver so that you can boot from it.

    So it's a hybrid. The difference is which processor does the work - a PCI board processor or a MB processor. You can't lump it with OS software raid that has no assist from the chip set, which is what software raid implies. It also ports among OSes. I can use my Intel RAID in Linux as well as Windows. My point is you shouldn't generalize like that. It's misleading.

    I like how no one really responded to my post lol. as far as using a 14.xxx driver as i stated in my post those drivers are incompatible with my chipset.
