    Thank you for re-stating what I was trying to convey, but this is why the tech will stay around longer than it should!

    I did notice very small bump over sata (850 Evo vs WD Black) and i think there would be a tiny bit more with better cpu.

    For me personally M.2 was just one more option to increase the storage drive count. I have three HDDs, two sata SSDs, and an optical drive, so I ran out of sata ports (since typical mobos only have six). With M.2 NVMe I could add one more, which was nice. M.2 sata, however, would have instead made two sata ports inoperational! Such utter waste.

    From my point of view M.2 sata is the pointless one, which is why I only talked about M.2 instead of M.2 NVMe. But of course it was inaccurate. Btw, NVMe also applies when you have an SSD directly in a PCIe slot, so unfortunately your correction to our talk was also inaccurate... NVMe simply refers to an SSD working via PCI Express. Thus the physical slot doesn't matter as long as it supports PCIe.

    Never said otherwise.... SATA is still ridiculously common and widely supported. it will take some time.
    NVme is obviously the future

    This is not entirely correct. What you are talking about are new gen motherboards that have a Z chipset... and yes, in this case it is true, you get 24 lanes that aren't connected to the 16 lanes provided by the cpu. But only fairly highend and expensive motherboards have a Z chipset, and most people don't spend alot on an expensive motherboard. Those that do usually buy higher end cpu's that have more than 16 pcie lanes in the first place. But you are correct that m.2 in most cases use the 4 pcie lanes that the chipset uses to connect to the cpu - but then again, i wasn't specifically talking about m.2, as alot of people are still on older gen hardware, that does not have a m.2 slot.

    That's something different, my motherboard does not have a PLX chip. A Z370 has 16 cpu lanes (16*1, 8*2 or 1*8+2*4), and 24 chipset PCIE lanes and no PLX chip. If you go right down to a budget B360 you still get 16 cpu lanes (16*1) and 12 chipset PCIE lanes.

    I see you are replying to my non-updated post.

    Regardless it doesnt really matter, because as i said, i wasn't specifically talking about m.2. For anyone with pre 6th gen cpu's (which alot of people still have), you don't have an m.2 slot, and in that case you will have to use the pcie slots to use a NVMe ssd, and that will limit the available pcie lanes to the cpu.

    Yes it would be, get a large m.2 and put all your OS's on one drive, DONE. Or use m.2 extension ribbons and modify your bays with those so you can have your "separate bays" but now with m.2's. Obviously your capabilities with SATA are greater since its an entrenched tech unlike the newer m.2. I will foresee SATA going by the wayside and PCI SSD being the only option.

    Perhaps in the distant future - lots of people are still on older hardware that does not have an m.2 slot, where sata is the only feasible option. As long as that remains the case, there will be sold sata ssd's.

    I understand that and agree. At some point folks are going to upgrade and I hope they will not "waste" money on an older cheaper board and go with one which has plenty of m.2 because only this will obsolete SATA in the near future. I remember when I upgraded I knew I wanted to future proof my build so I got a board that had m.2 NVMe support. We all at one point or another have some technical Cognitive dissonance which albeit being human nature can afflict even the best of us.;)

    Now they are fast enough to be noticiable, also the price tend to be the same or less expensive.

    Same way as with HDD, plug the new one on empty port then clone the old on new and remove the old one, and, if bigger, resize the partition.
    if you have only one port there is PCIe, SATA or USB3 adaptator to do it (for cloning it is fast enough).
    *edit* if it is for OS you better do a fresh instal and only transfer the data.

    The problem I have with M.2 drives is when I upgrade to a faster drive I cant continue to use the old one, I dont sell old kit.
    My mobo has one M.2 port and the spare PCI-e x4 slots are covered by 2 wind tunnels feeding my gfx card.

    SATA isnt dead until M.2 (or something else) have as many ports and are just as easy to use as SATA.
    With it being SSD only, sizes need to grow hugely and prices drop otherwise SATA will be the only option for local cheap, vast storage.
    I dont even have an M.2 drive yet because they are small, expensive and not much quicker than SATA SSDs in real use.
    I'm luke warm on a 1TB M.2, I wont buy less than a 6TB hard drive.

    From what i can tell, the ones that will see a benefit from SATA to NVME are people working with stuff that have lots of tiny files.
    And i'm talking lots of files that hold metadata that never go above the minimum file size for their file-system.
    Do lots of creation/moving around of 2-4KB files? you'll see an improvement.
    Not from the PCIe speeds, but from the command queue.

    Give us m.2 ports and cables so u dont need the wasted space on the motherboard and can have 6 ports stacked on the side of the motherboard the way SATA ports are now would make life much easier. I guess there are some obvious reason why they dont do this though but I can dream right?

    heat, and in the way of pci cards, id imagine why.

    My 2 cents:
    M.2 slot is a godsend because removes cable clutter.
    Could it be improved? Of course.
    And newer platforms already offer more PCI-E lanes as we used to have from older blue chip vendor.:rolleyes:

    what doesnt matter is the port-slot/plug right ? there is U.2 that using cable that similar to SATA no?
    and someone can make extender-cable like pci-e gpu cable

    the problem with m2/nvme is limited pci lanes that can be used for various device, not like sata-lanes that dedicated for storage

    well the trend will bring the change to mobo, just like what we experience in past
    IDE/PATA/SCSI -> SATA/SAS -> now NVME(PCIe)
    so the transition is not a thing to worry about

    with current trending, i guess we will getting more and more PCI-lanes, except intel/AMD decide to make new bus interface dedicated for storage

    SATA SSDs limited lol? For a very small niche of applications. Gaming will see almost no benefits at all from it. And people like me will upgrade to a 2TB SSD probably next year for the PC, of course on SATA as that is all I have on my now ancient but still very decent MSI board. I even have PCIe 3 on this board if I upgrade my CPU to Ivy lol. IVY.

    Don't laugh it just because you don't see a benefit to it. Depending on your phone, you are probably using something like an nvme on that one ;)
    An iphone SE for example is using a PCIe flash memory controller.
