EXPERT FEATURES

  • 4TB High-Capacity Storage : Packs 4,000GB of fast solid-state storage for large game libraries, high-resolution media, creative projects, applications, and heavyweight work files without constantly playing storage Tetris.
  • Up To 7,250MB/s Sequential Read : Delivers extremely fast sequential read performance for rapid loading, file access, application startup, and high-throughput workloads on a properly configured compatible system.
  • Up To 6,300MB/s Sequential Write : Handles large file transfers, installations, exports, and demanding write-heavy tasks at speeds reaching 6,300MB/s with Intelligent TurboWrite active under supported conditions.
  • High Random Performance : Reaches up to 1,050,000 random-read IOPS and 1,400,000 random-write IOPS, helping improve responsiveness during multitasking, game loading, and application-heavy workflows.
  • PCIe 4.0 And PCIe 5.0 Flexibility : Supports PCIe 4.0 x4 and PCIe 5.0 x2 through the NVMe 2.0 interface, giving compatible modern systems flexible high-bandwidth installation options.
  • PCIe 3.0 Backward Compatibility : Can operate in compatible PCIe 3.0 x4 systems, although actual speed will be limited by the older interface and the host system’s hardware configuration.
  • Samsung V-NAND TLC : Uses Samsung V-NAND TLC flash memory and an in-house Samsung controller for tightly integrated performance, firmware management, and reliability.
  • Host Memory Buffer Design : Uses HMB to access a small portion of compatible system memory for SSD management, delivering efficient performance without requiring a separate onboard DRAM cache.
  • Intelligent TurboWrite 2.0 : Enlarged TurboWrite technology accelerates supported write operations and helps the 4TB model process large datasets, game installations, and graphics-heavy files more efficiently.
  • Improved Power Efficiency : Provides up to 73% more performance per watt than the previous 990 EVO, reducing power demands while maintaining thermal control and sustained everyday performance.
  • Compact M.2 2280 Format : Measures a maximum of 80.15 × 22.15 × 2.38mm and weighs up to 9g, fitting compatible desktops and laptops equipped with an NVMe-capable M.2 2280 slot.
  • AES-256 Hardware Encryption : Supports AES 256-bit full-disk encryption, TCG/Opal 2.0, and Microsoft Encrypted Drive IEEE 1667 for compatible secured-system deployments.
  • Samsung Magician Management : Samsung Magician supports drive-health monitoring, performance optimisation, firmware updates, security functions, and data-migration tools for easier SSD maintenance.
  • 2,400TBW Endurance : The 4TB model carries an endurance rating of 2,400 terabytes written, backed by a one-year limited warranty or the TBW limit, whichever is reached first.
