The Samsung 990 Pro is a PCIe 4.0 x4 NVMe M.2 2280 internal SSD with 4TB of TLC 3D NAND and AES-256 encryption with TCG Opal 2.0 support. It is one of the fastest PCIe 4.0 drives made, with sequential reads near the interface limit and strong random performance for gaming and heavy multitasking. The 4TB model is the roomiest in the line and uses a full four-lane design, so it suits desktops and laptops with a free M.2 slot. Rivals like the WD Black SN850X and Crucial T500 come close in speed, but the 990 Pro is known for consistent sustained performance and low power draw rather than a big lead.

Owners and reviewers rate the 990 Pro among the best PCIe 4.0 drives, praising its speed, consistency and software. Complaints center on heat under heavy writes and the modest real-world gain over the 980 Pro.
The Samsung 990 PRO 4TB is an internal M.2 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 TLC flash.
It uses the M.2 2280 form factor, a 22 × 80mm module, and is meant for a compatible desktop, laptop or workstation. It supports AES-256 encryption and TCG Opal 2.0. Using these features depends on compatible software, host support and configuration.
The host needs an M.2 slot that supports 2280-length PCIe NVMe SSDs, enough installation clearance and support for a 4TB drive. An M.2 slot that supports only SATA storage is not suitable. The drive cannot directly replace a 2.5-inch SATA drive, because it uses a different physical format and connection. Existing files do not transfer automatically.
