Is the 990 PRO worth it over the 980 PRO?

Yes if you want the fastest PCIe 4.0 speeds and better efficiency. The 990 PRO is over 55% faster in random performance and uses less power per unit of work, so it is a clear step up for heavy workloads.

Does it need a heatsink?

This version ships without one. For sustained large writes, especially in a desktop or PS5, a heatsink or motherboard M.2 shield helps it hold peak speeds.

Will it work in a PCIe 3.0 slot?

Yes, it is backward compatible, but it will run at PCIe 3.0 speeds, so you won't see its full rated throughput.

Is it compatible with a PS5?

Yes, the M.2 2280 form factor fits the PS5 expansion slot. Sony recommends a heatsink, so pair it with one for steady performance.

The drive itself and documentation. No heatsink, screws or mounting hardware are included.

How does it compare with PCIe 5.0 drives?

PCIe 5.0 drives are faster on paper but run hotter and cost more. For most gaming and everyday work, the 990 PRO's Gen 4 speed is already more than enough.

Our take on the Samsung 990 PRO PCIe 4.0 NVMe M.2 SSD 4TB

The Samsung 990 PRO is a PCIe 4.0 NVMe M.2 drive built for speed: rated up to 7,450 MB/s read and 6,900 MB/s write, with random performance more than 55% above the older 980 PRO. The 4TB model gives large game libraries, video projects and datasets room to live on one drive. A nickel-coated controller and Samsung's thermal control keep speeds steady under load, and Magician software handles health monitoring and firmware. It is one of the fastest PCIe 4.0 drives you can buy, though PCIe 5.0 drives now beat it on paper and run hotter and pricier.
