Samsung 990 EVO Plus 4TB M.2 2280 PCIe 5.0 x2 Internal SSD

The Samsung MZ-V9S4T0B/AM is a 4TB solid-state drive that slips into an M.2 2280 slot and connects through PCIe 5.0 x2 or PCIe 4.0 x4. It gives desktops, laptops, and compact workstations an uncomplicated path to very high storage performance without adding cable clutter.

Powered by Samsung V8 TLC NAND flash, the drive reaches sequential read speeds up to 7250 MB/s and write speeds up to 6300 MB/s. Random performance peaks at 1,050,000 IOPS for reads and 1,400,000 IOPS for writes, helping operating systems boot quickly, large projects open almost instantly, and demanding games load with minimal waiting.

Built-in AES 256-bit hardware encryption works alongside TCG/Opal 2.0 and Microsoft eDrive standards, securing sensitive data without placing extra load on the host CPU. This security-first approach benefits business laptops, workstation towers, and any environment where confidential files must stay protected.

An endurance rating of 2400 TB written supports years of heavy use, whether you are moving terabytes of footage, compiling massive codebases, or syncing cloud libraries. Even during intensive transfers, the drive typically draws only 5.5 watts and drops to about 60 milliwatts when idle, which helps manage thermals and preserve battery life in portable devices.

Content creators editing high-resolution video, gamers aiming for shorter load screens, and professionals juggling large data sets will all find the 990 EVO Plus a reliable foundation for smooth, responsive workflows. Installation is tool-less in most modern systems, making the upgrade straightforward for enthusiasts and first-time builders alike.
