The Samsung 990 Pro is a PCIe 4.0 x4 NVMe M.2 2280 solid-state drive built on TLC 3D NAND, here in a 4TB capacity. It is one of the fastest PCIe 4.0 drives made, with sequential reads near the ceiling of the interface and strong random performance that keeps games and large files loading quickly. It suits desktop and laptop upgrades, game libraries and creative work where capacity and speed both matter. Against PCIe 5.0 rivals it runs cooler and draws less power, though it gives up some peak throughput; against budget PCIe 4.0 drives it costs more but holds speed better under sustained writes.

Reviewers rate the 990 Pro among the best PCIe 4.0 drives, praising its speed, efficiency and thermals. Owners report fast boots, quick game loads and stable long-term performance, with cost the main complaint.
The Samsung 990 PRO 4TB is an internal solid-state drive with no spinning disks. It connects over PCIe 4.0 x4 and uses the NVMe 2.0 protocol. It is built with 3D NAND and TLC flash.
It comes in the M.2 2280 format, a compact 22 × 80mm module. It supports AES-256 encryption and TCG Opal 2.0. Using these security features depends on compatible software, host support, and configuration.
The drive needs an M.2 slot that supports 2280-length PCIe NVMe SSDs, enough installation clearance, and system support for a 4TB drive. An M.2 slot that supports only SATA storage is not suitable. It cannot directly replace a 2.5-inch SATA drive because it uses a different physical format and connection. Installing it does not transfer existing files, so plan a separate migration or a fresh installation.
