According to our solid state drive (SSD) expert
Note: this M.2 SSD has a PCI Express 4.0 (NVMe) interface, and will only work if your system supports PCIe 4.0/NVMe. This SSD also has an M key, which only fits on systems with an M slot. Make sure to check this in the manual of your laptop or motherboard.
Store the largest games on the WD_BLACK SN7100 4TB NVMe internal SSD for desktops and laptops. This SSD has a 7000MB/s read speed and 6700MB/s write speed. That way, your games boot quickly and you don't have to wait for long loading screens. You can store up to 100 medium-sized games on this internal disk thanks to the 4TB storage space. You can also transfer your files faster thanks to the PCle 4.0 interface. This internal SSD is also more energy-efficient than the WD SN770 NVMe SSD, so the battery lasts longer.

I use the NVMe SSD in a home lab, a mini server (Dell Optiplex mini) on which I run multiple services simultaneously in containers and VMs. Everything feels smooth thanks to the speed of this SSD.
