about intel optane memory + NVMe™ M.2 SSD

nitially

intel optane memory M10(16,32,64gb)PCIe NVMe M.2 3.0x2 was for accelerating 2.5'SATA mechanical HDD regardless of which generation intel CPUs.

also note :

not talking about Intel® Optane™ Memory H10 with Solid State Storage (32gb+1tb, 32gb+512gb ,16gb+256gb)PCIe NVMe3.0x4 that comes as a single m.2 drive which is mounted on single m.2 slot

but now why

intel optane memory M15(16,32,64gb)(PCIe NVMe 3.0 x4)is-- paired with --PCIe® NVMe™ M.2 SSDs {which is mounted on two differnt m.2 slots on 7th ,8th and 9th gen intel CPUs}

what is the purpose

ex: 512 GB PCIe® NVMe™ M.2 SSD + Intel® Optane™ memory 32 GB on (Intel® Core™ i7 9750H) seen from HPs Omen X 2S - 15 Gaming Laptop.

 

Clone present nvme pcie ssd to replacement nvme pcie ssd?

I have a 500GB M.2 2280 NVMe PCIe SSD (boot drive) that I want to replace with a higher capacity M.2 card.

Where do I put the new SSD during the NVMe to NVMe cloning process? My mobo only has one M.2 slot for NVMe SSD's so do I want to use an external adapter for one of the M.2 cards? If so, do you have a recommendation?

If you have solved this issue for your desktop or laptop I would like your advice on if and what extra hardware you needed during the cloning.

please remember that I am dealing with PCIe NVMe drives ONLY. NO Sata is involved except possibly for a connecting cable from the desktop to an adapter. I am experienced with cloning SATA III drives but cloning NVMe is a little
new to me.

Computer: Dell XPS 8920, 32GB ram.

Present SSD: KXG50ZNV512G NVMe Toshiba 512GB

New SSD: CT13049074 Crucial P1 NVMe PCIe M.2 SSD 1TB (or 2TB if available soon) or similar storage device.

Upgrade m.2 NVMe 256GB SSD to a larger m.2 NVMe SSD

I have an HP EliteDesk 800 G5 Mini PC and would like to change the boot WD_Black SN720 256GB NVMe m.2 SSD for a WD_Black SN850 500GB NVMe m.2 SSD.There are 2 NVMe M.2 slots and already have installed a WD_Black SN750 1TB NVMe Internal SSD in the second slot as a Data drive.What is the easiest way to clone my present boot m.2 SSD to a new WD_Black SN850 500GB NVMe m.2 SSD?Would I have to purchase an External USB Gen 2 NVMe enclosure as I have USB Gen 2 slots on this PC?
