Is the 990 PRO worth it over cheaper PCIe 4.0 SSDs?

If you want top PCIe 4.0 speed, strong sustained writes and hardware encryption, yes. For basic storage, a value drive feels similar in everyday use.

Does it need a heatsink?

This version has no heatsink. It works bare, but a motherboard M.2 heatsink or good airflow is recommended for heavy sustained writes.

Is it compatible with a PS5?

Yes, the M.2 2280 form factor and PCIe 4.0 interface meet the PS5 requirements. Sony requires a heatsink for the console, so use a heatsinked version or add one.

How does it compare with the 980 PRO?

The 990 PRO is faster, especially in random reads and writes, and more power-efficient. The 980 PRO remains a solid cheaper alternative.

Does it support encryption?

Yes. It supports AES-256 and TCG Opal 2.0, usable with compatible BIOS and software encryption setups.

The drive itself. No heatsink, cable or mounting screws are included, since M.2 drives mount directly to the motherboard.

What reviewers say

Reviewers and owners rate the 990 PRO as one of the best PCIe 4.0 SSDs, praising its speed, sustained performance and software. Complaints center on value against cheaper drives and on heat and firmware issues reported early in its life.

What people mention

SpeedPraisedOwners say it feels fast in boot, game loads and large transfers, and benchmarks put it near the top of PCIe 4.0.
Sustained writesPraisedReviewers note it keeps high write speeds during long transfers rather than dropping sharply.
HeatMixedIt runs warm under heavy sustained writes; most say a motherboard heatsink or airflow is enough.
ValueCriticisedSome buyers say cheaper PCIe 4.0 drives feel nearly as fast day to day for less.
FirmwareCriticisedEarly buyers reported health readings dropping fast; firmware updates were said to address it.
SoftwarePraisedSamsung Magician is called useful for firmware, health monitoring and over-provisioning.

About the Samsung 990 PRO 1TB PCI Express 4.0 x4 NVMe 3D NAND TLC M.2 2280 Solid State Drive (SSD)

The Samsung 990 PRO is a 1TB internal solid state drive that connects over a PCI Express 4.0 x4 interface using the NVMe protocol. It uses 3D NAND TLC flash memory and comes in the compact M.2 2280 form factor, which is an 80mm module.

It supports AES-256 encryption and TCG Opal 2.0 security. It can be used as primary storage in a compatible desktop or workstation, for the operating system, applications and project files, or to replace an M.2 2280 NVMe drive.

The host system needs an M.2 2280 slot that supports PCIe NVMe drives. PCI Express 4.0 x4 capability is needed to use this interface generation and lane configuration. Some M.2 slots support only SATA devices or other module lengths. Check motherboard or system support, slot dimensions, boot compatibility, available PCIe lanes and cooling requirements. The host platform and software must also support the security configuration you plan to use.
