Samsung - 970 EVO 500GB PCIe Gen 3 x4 NVMe Internal Solid State Drive with V-NAND Technology

Samsung 970 PRO uses latest Samsung 64-layer 3D MLC V-NAND whereas the Samsung 970 EVO uses Samsung 64-layer 256Gb 3D TLC. Both use the same Samsung Phoenix NAND controller. 970 PRO is a little faster for sequential and random writes and uses a little less power. Here's a link to a comparison: https://www.anandtech.com/show/12674/samsung-announces-970-pro-and-970-evo-nvme-ssds There is also a new 970 EVO Plus which utilizes a burst write buffer to improve write performance for most application that produce bursts of write but not sustained writes. Here's a link to performance comparison of all 970s. https://www.pcworld.com/article/3334876/computers/samsung-970-evo-plus-review-samsungs-entry-level-nvme-ssd-is-faster-and-cheaper.html

Yes. according to lenovos website it does have an M.2 Port inside. it will require some moderate dissassembly but its easily doable.

Yes it will work as long as you have an m.2 slot on your motherboard. I swapped out the optane memory board to do this on my dell desktop

After looking at the specs for the XPS 15 9560 here: https://topics-cdn.dell.com/pdf/xps-15-9560-laptop_specifications_en-us.pdf, Yes this drive will work in that model of laptop. The XPS 15 9560 has 1 M.2 interface which is what you need for this SSD.

I could not find MSI GS63VR6F on a quick Google search. Did you mean the GS63VR 6RF Stealth Pro? If so, it looks like this SSD will work in your laptop, provided 2 things: 1) This SSD requires an M Key socket, which means the connector on the card has a small notch toward the right hand side (from the perspective of looking into the socket). A B Key socket, on the other hand, accepts a card with the notch toward the left hand side. Some sockets accept both B Key and M Key cards. 2) This SSD has a 2280 form factor, meaning the card is 22mm wide on the connector side and 80mm in length. So the motherboard in your laptop would have to have the physical space and a screw & standoff 80mm from the socket to secure the far end of the card. I do not see in the specs of this laptop what form factors of M.2 SSDs it will accept. Your best bet may be to open up the case, pull out the current card if necessary, and look at the socket type and card lengths it will support.
