Is the 990 Pro worth it over cheaper Gen 4 SSDs?

If you want top Gen 4 speed, efficiency and Samsung reliability, yes. For light everyday use a value Gen 4 drive feels similar and costs less.

Does the 4TB model perform like the smaller capacities?

Yes. The 4TB version uses the same controller and NAND and is rated at the same top sequential speeds as the smaller 990 Pro models.

Does it need a heatsink?

For normal desktop and gaming use the bare drive is fine. For long sustained writes, such as large video exports, a heatsink or motherboard cover helps keep temperatures down.

Is it compatible with a PS5?

Yes, it meets the PS5's M.2 size and speed requirements, but Sony requires a heatsink, so use a heatsink version or add one.

How does it compare with the 980 Pro?

The 990 Pro is faster and more efficient, with the biggest gains in random performance and sustained writes. Upgrading from a 980 Pro is only worthwhile for heavy workloads.

The drive itself, with all original boxed contents included. Mounting screws and a heatsink are not part of the standard package.

Our take on the Samsung 990 Pro 4TB M.2 NVMe Gen 4.0 x 4 SSD

The Samsung 990 Pro is a PCIe 4.0 NVMe M.2 SSD built on Samsung's in-house controller and V-NAND, and the 4TB model is the largest capacity in the line. It is one of the fastest Gen 4 drives available, with sequential reads near the ceiling of the PCIe 4.0 interface and strong random performance that matters more for everyday loading and game installs. It suits gamers, content creators and anyone moving large files who wants top-tier Gen 4 speed and a long warranty rather than the lowest capacity per dollar. Against Gen 4 rivals it trades on sustained speed and power efficiency; against newer Gen 5 drives it gives up peak throughput but runs cooler and needs no extra cooling.

Samsung controller and V-NAND with a five-year warranty
4TB capacity holds a large game and project library on one drive

Cons

Premium drive, so it costs more than value Gen 4 models
Runs warm under sustained writes and benefits from a heatsink
Gen 5 drives beat it on peak sequential throughput
No dramatic gain over the 980 Pro for light everyday use
