Our take on the Samsung 990 PRO 4TB M.2 2280 PCI Express NVMe 4.0x4 Solid State Drive

The Samsung 990 PRO is a PCIe 4.0 NVMe M.2 2280 SSD built on Samsung's own controller and V-NAND. The 4TB version gives you a huge single-drive capacity at sequential read speeds up to about 7,450 MB/s, near the ceiling of PCIe 4.0. It suits gamers, video editors and anyone moving large files who wants top-tier Gen4 performance without stepping up to a Gen5 drive. Against Gen5 rivals it runs cooler and draws less power; against cheaper Gen4 drives it costs more but holds speed better under sustained loads.

Questions and answers

Is the 4TB 990 PRO worth it over a cheaper Gen4 SSD?
If you move large files or want consistent speed and low heat, yes. For everyday use a value Gen4 drive feels similar and saves money.
Does it fit a PS5?
Yes. It is a single-sided M.2 2280 drive, which fits the PS5 slot. Add a heatsink, since the standard model has none.
Do I need a heatsink?
For gaming and normal desktop use, no. For long video renders or sustained writes, a heatsink keeps speeds from throttling.
How does it compare with the 990 PRO with heatsink?
Same drive and performance. The heatsink version adds a built-in cooler for sustained workloads and costs more.
Is it faster than a Gen5 SSD?
No on peak sequential speed. It runs cooler and draws less power, and most real-world tasks feel the same.
What is in the box?
The drive itself. No cable, screw or heatsink is included, so check your motherboard or PS5 for mounting hardware.
