I want to insert a SSD into Dell Precision 3561.
The specs says that there are two M.2 2280 slots for solid-state drive 256 GB/512 GB/1 TB/2 TB.
I tried to insert a SAMSUNG 860 EVO which could fit the slot. However, either in boot menu nor in Windows the SSD is recognized.
Note: the SSD is not clean: It contains Ubuntu, GRUB and NTFS partitions.
Here is the picture of the slot:
What do these texts mean: "This SSD requires termal plate" and "no hybryd Optane/SATA?
Thank you for your help!
