    M16 Raid 0 Performance not as expected

    Hello Everyone.
    I hope everyone is doing well...

    Recently acquired a best buy GU603HM. This has the I9-11900H and a 3060 graphics card.

    This laptop is supposed to be PCIe Gen 4 and according to CPUZ it is.

    I installed a pair of 980Pro 2 TB Drives. I was able to clone properly the factory system into this RAID array using paragon-software. Laptop boots fine and no real issues.

    When running crystal mark 7.0 I am getting the following read/write speeds.

    https://prnt.sc/1qvorgf

    I find this to be half of what you would expect from these drives.

    What are the possible situations?

    Is it that one of the PCIe M.2 Slots is Gen 3 and the other is Gen 4?

    For a laptop that supports raid from the bios, this would seem like a bad choice, but I have seen it in other laptops.

    If this is the case, then you are losing performance as apparently you get a loss in performance in the random category when using raid 0 with M.2 SSDs.

    Any advice would be welcome.

    I like this machine but it could be a deal breaker and getting the AMD Advanced would be the way to go.

    You are running - strip 0 and what byte size ?

    Also why RAID ?
    I get it will win every benchmark but I doubt you can feel or measure the difference NVMe without it vs one in RAID in the real world (unless it real RAID SAS with real controllers not onbaord ones)

    Honestly.. boot times and I have a couple of programs that I could use that extra difference. Plus I can see both drives as a single drive. Nice having 4TB single drive

    My system boots in 12 seconds on Windows 10 default load and 15-18 seconds with my loadout. Just baseline for you.

    I think not having identical drives in raid is going to limit to slowest drive.

    Hope this is helpful.

    Nope, thats about all you get on a laptop. The raid controller is downstream of the DMI BUS. Could have told you that beforehand. literally everything on the laptop goes down 4 shared lanes.

    They are identical. 2tb 980Pros both. 4tb total. I was wondering if one of the slots is PCIe 3 and the other is PCIe 4.

    Any way to figure it out?

    Thanks

    I think its more that the main m.2 slot is going straight through the processor and the secondary slot is going via the pch.*

    Otherwise both drives would perform the same independently just bottlenecked together and this is not the case.

    I guess this was intended to have one optane drive and one regular data drive.

    I need to do more testing to see if raid still offers benefit even while max throughput is maxed out as for one. Its one single logical drive and 2 i wonder if they use the cache combined and that could make it quicker for smaller tasks which is what i want to speed up.

    Raid0 may give you large sequential read numbers but thats not what counts. Everyone seems to be hung up on that.
    The latency of the raid hits the low que depth 4k random reads pretty hard. This is where the performance counts unless you spend all day transferring large files from one drive to another the large sequential numbers dont mean anything. Its the bottom numbers you didnt show that make the difference in speed of the machine as most of the OS and apps are comprised of 4k dll files. Run the 4K all the way at the bottom and see what you get as that's what counts. That's where Optane drives excel.
