  ACCC thinks its cute when a retailer tries to modify the manufacturer's warranty.

  Lucky they in the USA. Probably best avoided

  Now we just need a deal on the Minisforum MS-01 that comes with a U.2 slot natively.

  MLC is a rarer sight these days unfortunately.

    Sadly the MS-01 only allows for a 7mm SSD, i think these ones are 10mm

  Is there any such device that will take a single NVMe gen 4 and turn it into 2× NVMe (or U2) gen 3?

    Spare PCIe slot? There are cards available.

    Short answer:

    Don't bother, it's too expensive and complicated. Either use an adaptor from a PCIe slot on the motherboard, or failing that just buy a better CPU, motherboard, etc. to give you the extra PCIe slots.

    Long answer:

    There are various adaptor cables available on the market that convert a m.2 connector to something else; but I have not seen any indication of any that would plug into an M key m.2 socket and break the PCIe lanes out into 2x connectors each carrying PCIe x2 (two lanes), as that is not something much demand exists for.

    M-key is the one used by NVME SSDs, specced for 4 PCIe lanes.
    The simpler your requirements the more likely you are to find a product that does it. Simple extenders and adaptors that convert 1:1 are common, while things that bifurcate/split the M.2 connector's PCIe lanes up are not something I've heard on.

    Bifurcation isn't something you can rely on having, especially on consumer hardware.
    You'd need to check the specs of the CPU, motherboard, motherboard chipset; and likely want do real-world testing to confirm it actually works as stated.

    Some nicer (typically workstation or server) motherboards have Occulink sockets which you can plug an occulink to U.2/U.3 cable into (Be sure to check the specific cable is suitable for your motherboard and your intended use, this stuff has various gotchas where you can end up with something incompatible)

    I would expect to need to hire an electrical engineer to design and produce together such an adaptor as a custom job.
    If they're not a crook they'll try to caution and dissuade you from this endeavor.

    There also exist various PCIe cards and ICs for PCIe signal handling - retimers, switches, etc; but if you think you need one I'd advise just paying for a consultation from an EE or technician about what would suit your needs, then phone the sales rep for the product before you buy it to make sure it's fir for your purpose. This is because such equipment can get expensive, even used.
    "Tri-mode" NVME/SAS cards are a good example, and the only one I'd be confident in actually buying without calling an expert first.

    To get a feel for what's available take a look around on the usual suspects like amazon US, ebay, aliexpress, and maybe specialist electronics parts vendors like digikey, mouser, farnell, etc. You'd be trying search terms like "m.2 adaptor"

    Here are some examples of what people are selling, (Not an endorsement of these, just some of the first listing results):
    - "M.2 to U.2 U.3 SSD High Speed Adapter Cable PCI-E 4.0 GEN4 Riser Card with SATA Power Supply for M2 NVME 2230 2242 2260 2280 SSD"
    - M-key M.2 extender

    I hope this overview helps; PCIe is a rather complicated rabbithole to dive down into.

    You would be something like a m.2 to dual U.2 with a PCIE bridging chip (such as PLX 8747). Without this chip your motherboard would need to support bifurcation on the m.2 slot.

    I have yet to find something such as dual u.2 + bridging chip on a m.2 adapter, so you'll need to look at PCIE adapter.

    For PCIE x16 to dual U.2 with a bridge chip, you'd be looking at something like this:

    For PCIE x16 to quad U.2 on a budget, you'd be looking at something like this plus 4 m.2 to u.2 adapters:

    If you want something like PCIE x16 to 8 port U.2 with a bridging chip, be prepared to throw money at the wall:

    didn't neg but had this saved in drafts might explain

    mechanical vs NVME (x5-10 faster again than the usual 2.5" SATA SSD)
    2TB vs 4TB
    used vs new
    much slower sequential read/write
    substantially slower random read/write
    oranges vs apples

      sure but still a viable small factor server storage option compatible with home pcs, these are enterprise drives but with SATA instead of SAS

      much faster, more reliable than consumer grade hdds and nvmes

      unless the application demands specifically for constant nvme speeds then these drives are just as serviceable, no problem slicing an enterprise drive like this into multiple vms

      tell them the price son

      these aren't as different as you (+ neggers) think, form factor, reliability, application all apples vs apples, they are just a little slower but still levels above consumer nvme and hdds for server applications
