    I've got an SSD and some older HDD's.

    I'd like to RAID 0 the HDD's but only if the SSD (which won't be in RAID array) will still be able to support TRIM.

    It's a Samsung 840 Pro and would be on a Z170 board.

    Are you going to be using raid 0?

    did a little look online and came across this link

    https://communities.intel.com/thread/105184

    with the below quote.

    so if the above site is correct, trim should work in raid 0 configuration.

    Yes 2 HDD's in RAID 0
    While the SSD is going to be the C drive on its own.

    RAID 0 for SSD is stupid. Basically e-peen.

    I believe in your use RAID 0 you lose TRIM

    Not really, I understand that the performance gains will be next to zero, but the cost of a 2TB ssd was more than twice that of a single 1TB ssd when i wanted to buy. I have two 1TB ssd's stuck together in raid 0, not for performance but for capacity (just for my steam folder really).

    I have just changed my setup.

    I have 2 x Samsung 850s 250gb drives which I have stuck in to raid 0 so its one drive instead of two.

    I have a third SSD for the OS.

    when I run this is command prompt

    fsutil behavior query disabledeletenotify

    its set to 0 so TRIM is enabled if it was 1 then it would be disabled, this is on a x58 board using intel controller.

    im using windows 7
