    "Did I REALLY just read what you just posted...?" might be a simplistic reaction/thought, I'm guessing...

    A tad didactic, no?

    Yeah, not that either.

    It feels more of a layered response. Like a cake. I can see the cake but the layers are hidden.

    And the cake is a lie.

    That would be fun... in a 15th floor flat. :p

    Anyway; enough derailing, already...

    The cake is a lie because when talking layers everyone knows it parfait, err I mean onions.

    OK, so the nvme to pcie adapter isn't awesome. It works. Kind of. There are issues though.

    It'll occasionally drop the connection and won't reconnect without a reboot, and about one in five cold boots wouldn't initialise the 10Gb NIC in the slot.

    Anyhoo, I found a three slot mobo with a 4x pcie slot that fits in the M1.

    So far so good. :)

    So, I've been playing around on my NAS with a couple of 1TB SSDs that I'm not currently using...

    A single SSD in the NAS is hitting 480+MB/s when moving large files like video or OS images. Two of them in RAID0 produce 800+ MB/s.

    I have strong but entirely unjustified urge to buy four large capacity SSDs and array them in RAID10.

    I think I need an intervention because this rabbit hole looks bloody deep.

    Would knowing that I've spent circa £5000 on "pimp my storage/network" help you step back from the precipice?

    That said, I've bought/sold/designed/built/looked after storage systems in the tens off millions too, so fair to say the hole runs a lot deeper.

    That's a scary thought.

    Have you created a RAID-10 before, or are you wanting to do it for the sake of it...?
    Knowing you have an optimal 'need' for it may be the sanity check...

    Yes, I used to run a RAID10 array with spinning disks, but that was on a GbE link so the disk transfer rate saturated the link speed - the only tangible performance benefit was the rate rarely dropped greatly below link speed because the drive performance was improved, even on smaller files. The argument now is that striped SSD performance could almost saturate a 10GbE link in some use cases.

    I didn't say it was a strong argument - current performance is meeting the need I set before I started this, but the shiny thing impulse is an ever-present battlefront for me.

    "Step AWAY from the credit card...!"

    There, I intervened... (well; tried).

    Yeah, that worked. I only bought two 2TB SSDs. They arrived today.

    But...



    Write test isn't as impressive - but I messed up the screen capture and started an array rebuild before I realised
