Samsung 970 EVO Plus 1TB SSD is the best. In the Top 3 as for fastest read/write also one of the top rated for longevity or life span. yoga 7-15itl5 laptop motherboard, might be BIOS related but most likely the mobo has lane restrictions, it does not support any drive above 1TB SSD or any PCIe 4.0 NVMe m.2 SSD only a maximum of 1TB NVMe m.2 PCIe 3.0 ssd. If you install a new SSD with PCIe 4.0 ability it will only operate at the PCIe 3.0 data rate. When separating the back chassis cover, even though the yoga 7-15itl5 laptop is aluminum it still a soft metal and may bend. The main problem is getting the gap separation just to start prying open. Chances are you will need several guitar picks as they snap. Purchase a real jeweler bit kit for removing the T5 or T7 screws. Cheap pc tool kits include bits but often made of soft alloy and could easily strip the screw heads of your laptop and or Smart phone.

terrible design, any tips to prying it open? theres literally no gaps

Which SSD did you use to upgrade?I have one too, which size is the SSD?

Из видео я понял , что М2 разъем всего один. Значит Добавить SSD не получится. Надо только заменять. Жаль.

Does it have graphics card expansion?

thanks

This intel or amd?

Good job; but no need to disconnect the battery; it can be done in BIOS
