5. Nickel-Coated Thermal Optimization: High-efficiency heat dissipation design suppresses overheating and thermal throttling under sustained full-load operation, maintaining stable flagship speed in compact cases and workstation environments.
6. Enterprise-Grade Data Security: Integrated AES 256-bit full disk encryption, TCG/Opal V2.0 and IEEE1667 encrypted drive support, protecting commercial and personal sensitive data with zero performance overhead.
7. Samsung Magician Full Management: Supports real-time health detection, firmware updates, performance benchmarking and personalized optimization to keep the SSD running at optimal condition long-term.

Max Performance for Professional & Gaming Workloads

As Samsungs high-end large-capacity Gen4 flagship, the 990 PRO 4TB delivers top-tier PCIe 4.0 storage performance for demanding scenarios. Its 7,450 MB/s ultra-high read speed drastically reduces system boot time, application launch delay and large game loading screens. The 6,900 MB/s write speed accelerates bulk transmission of 8K raw video, large project files, game resource packages and massive backup archives, greatly improving creation and production efficiency.

Benefiting from upgraded 1.6 million random read IOPS, the 4TB model provides smoother response in complex stacked workloads including video rendering, real-time streaming, AI asset loading and multi-program simultaneous operation. The generous 4GB independent cache ensures more stable low-latency performance even when the drive is heavily occupied, perfectly matching long-hour professional creation and high-intensity gaming usage.

Optimized Thermal & Power Efficiency

Equipped with a nickel-coated controller and refined power delivery architecture, the 990 PRO 4TB achieves excellent heat dissipation and power balance. It effectively dissipates heat generated by continuous high-speed reading and writing, avoiding thermal throttling during long full-load operation. The optimized power consumption design maintains high performance while keeping energy efficiency stable, suitable for high-end desktops, small-form-factor builds and professional workstations with long-duration operating needs.

Superior Reliability & Complete Data Protection

Adopting Samsung self-developed V-NAND flash and exclusive Gen4 controller, the 990 PRO 4TB undergoes strict industrial-level reliability verification. It features a 2400 TBW ultra-high endurance rating, supporting years of frequent overwriting and intensive professional workloads. With a 1.5 million hours MTBF rating, it delivers outstanding long-term operational stability and service life.

Hardware-level AES 256-bit encryption encrypts all stored data in real time without occupying system resources or sacrificing speed. Multiple professional security standards ensure compliant, safe and reliable data storage for personal, studio and commercial scenarios.

Wide Compatibility & Simple Installation

Featuring standard M.2 2280 compact form factor, this SSD fits all mainstream M.2 NVMe slots on desktops, laptops and mini PCs. It runs at full speed on PCIe 4.0 motherboards and maintains stable backward compatibility with PCIe 3.0 platforms. It supports TRIM, garbage collection, S.M.A.R.T. and other mainstream functions, compatible with Windows, macOS and Linux operating systems.
