Samsung 990 PRO 4TB NVMe SSD, PCIe 4.0 M.2 2280, Up to 7,450 MB/s

The Samsung 990 PRO provides 4TB of solid-state storage in an M.2 2280 form factor. Its compact design suits compatible desktop and laptop builds where internal space is at a premium.

With a PCIe 4.0 x4 NVMe interface, it offers sequential read speeds up to 7,450 MB/s and write speeds up to 6,900 MB/s. Those transfer rates support demanding workloads that move or load large files.

Use it to expand a gaming setup, organize an operating system and key games on one drive, or add fast storage for video editing and data analysis. The 4TB capacity gives you room for a substantial library of projects and games.

How to use it

Install the 990 PRO in a compatible M.2 2280 slot in a desktop or laptop. To take advantage of its PCIe 4.0 interface and advertised speeds, the system must support PCIe 4.0. It is also listed as compatible with Sony PlayStation 5, making it a potential storage upgrade for a supported gaming setup.

For example, a PC gamer can use the drive for an operating system and frequently played games, while keeping other files on separate storage. If you are choosing between adding a high-capacity drive and splitting storage across several smaller drives, this single 4TB SSD offers space for a broad mix of games and work files.

What stands out

The combination of 4TB capacity and PCIe 4.0 NVMe speeds makes this drive useful for more than a basic storage expansion. Large game libraries, creative projects, and data-heavy work can share one internal drive, while the M.2 2280 format fits compatible systems designed for this size. Its sequential speeds are rated up to 7,450 MB/s for reads and 6,900 MB/s for writes, actual performance can vary with system hardware, configuration, and firmware.

Buyer feedback frequently highlights fast transfers, gaming use, and the available capacity. Some customers also report mixed experiences with drive recognition, thermals, and long-term reliability, so feedback reflects individual setups and outcomes rather than a guarantee. The product’s system compatibility and PCIe support remain practical considerations when planning an installation.

What to clarify

Does it work in any desktop or laptop? It is designed for compatible desktop and laptop systems with an M.2 2280 slot. PCIe 4.0 support is needed to access the interface’s full capabilities.

Can it be used with a PlayStation 5? Sony PlayStation 5 is listed as a compatible console. Confirm that the console’s installation requirements and the drive’s form factor suit your setup before installation.

What speeds are listed? Sequential reads are rated up to 7,450 MB/s and writes up to 6,900 MB/s. Results may vary with the system and its configuration.
