Is the 870 EVO 4TB worth it over a cheaper SATA SSD?

It costs more, but you get Samsung V-NAND, a five-year warranty and Magician software. If you want the lowest cost per terabyte, budget SATA drives do the same everyday job.

How fast is it compared with an NVMe drive?

It reaches about 560 MB/s sequential read and 530 MB/s write, near the SATA limit. A PCIe NVMe drive can be several times faster, but you will not notice it in most everyday tasks.

Will it fit my laptop or desktop?

It is a standard 2.5-inch, 7mm-thick SATA drive, so it fits most laptops and desktops with a 2.5-inch bay. Check that your machine has a SATA port rather than only an M.2 slot.

The drive itself. No SATA cable, screws or mounting bracket is included, so check whether your case or laptop needs them.

Can I use it in a PS4 or PS5?

It works in a PS4 as a drop-in replacement for the internal drive. The PS5 needs an M.2 NVMe drive for expansion, so this SATA model is not the right fit there.

How long will the 4TB drive last?

Samsung rates the 4TB model at 2,400 TBW, which is far more writing than most users do in five years. The warranty runs five years or to that endurance limit, whichever comes first.
