WD Black 1TB SN770 NVMe Internal Gaming SSD Solid State Drive - Gen4 PCIe, M.2 2280, up to 5,150 MB/s - WDBBDL0010BNC- WRWM

Very decent NVME when available at a discount. Do not buy these at MSRP, you can do better. Predictable performance, and speeds are as advertised. In terms of installation, things are fairly standard but with a caveat. If you plan to add a heatsink, be aware that the chip surface is highly uneven. This necessitates that you either choose a heatsink with a thick thermal pad included, use thermal putty, or provide your own thermal pad to fill in the low spot where the controller sits. This model is single sided, chips on one side only.
