Manufacturer description

The Samsung 990 PRO 1TB is a PCIe 4.0 M.2 2280 drive built to push the interface close to its ceiling, with sequential reads up to 7,450 MB/s and writes up to 6,900 MB/s. Random performance is where the generational jump shows: up to 1,400K read and 1,550K write IOPS, which Samsung rates at 40% and 55% faster random read/write than the 980 PRO. That translates into up to 65% better random performance for game loading on PS5 and DirectStorage PC titles, so asset streaming and level loads stop being the bottleneck.

Frequently Asked Questions

Will the Samsung 990 PRO 1TB work in a PS5?

Yes. It is a PCIe 4.0 M.2 2280 drive, and Samsung rates it for up to 65% improved random performance for PS5 and DirectStorage game loading. Sony requires a heatsink for PS5 expansion slots, so confirm you are buying the heatsink version or adding a compatible one.

How fast is the 990 PRO compared to the 980 PRO?

Sequential reads and writes reach up to 7,450 MB/s and 6,900 MB/s. Random read is up to 40% faster and random write up to 55% faster than the 980 PRO, at up to 1,400K/1,550K IOPS.

Does the 990 PRO fit in a laptop?

It uses the slim M.2 2280 form factor and fits laptops that meet the PCI-SIG D8 standard. Its nickel-coated controller handles heat, and the up to 50% better performance per watt over the 980 PRO helps battery life.

Is 1TB enough capacity for a gaming drive?

It holds a Windows install plus roughly a dozen mid-size titles, but modern AAA games can exceed 100GB each. If you keep more than a handful of those installed at once, step up to a larger capacity.

What software comes with the 990 PRO?

Samsung Magician, which monitors drive health, applies firmware updates, and provides optimization and data-protection tools. Check the product listing for current warranty terms and endurance ratings.
