The Samsung 990 PRO 4TB with integrated Heatsink is a premium high-capacity PCIe 4.0 flagship SSD engineered for maximum sustained performance and thermal stability. Built with Samsungs in-house Gen4 controller and reliable 3-bit V-NAND TLC flash memory, this pre-cooled model eliminates thermal throttling during long heavy-load sessions. Delivering upgraded 4TB-class random performance and massive storage space, it perfectly fits professional 4K/8K video production, large-scale game libraries, streaming workstations, and heavy multitasking scenarios. The factory pre-installed heatsink provides out-of-the-box stable peak performance, requiring no aftermarket cooling upgrades for long-duration high-intensity operation.

1. Flagship Gen4 Ultimate Performance: Officially rated up to 7,450 MB/s sequential read and 6,900 MB/s sequential write speeds. The 4TB model delivers upgraded 1,600,000 random read IOPS and 1,550,000 random write IOPS (QD32), offering ultra-low latency for gaming rendering and large-file batch processing.
2. Factory Integrated Premium Heatsink: Pre-mounted high-efficiency aluminum heatsink optimizes heat dissipation for continuous Gen4 high-speed operation, locking peak performance without throttling even under full-load long-time running.
3. 4GB Large Independent DRAM Cache: Equipped with exclusive 4GB LPDDR4 low-power cache, stabilizing low-latency multitasking performance and maintaining consistent speed even when the drive capacity is nearly full.
4. PCIe 4.0 x4 & NVMe 2.0 Protocol: Native full Gen4 high-bandwidth interface, fully backward compatible with PCIe 3.0 platforms, supporting all mainstream desktops, laptops and workstations.
5. Intelligent TurboWrite 2.0: Dynamic SLC caching technology sustains prolonged high-speed writing performance, avoiding speed drops during ultra-large file migration and continuous data overwriting.
6. Enterprise-Grade Data Security: Built-in AES 256-bit full disk encryption, TCG/Opal V2.0 and IEEE1667 encrypted drive support to protect sensitive personal and commercial data with zero performance loss.
7. Samsung Magician Software Support: Enables real-time drive health monitoring, firmware updates, performance benchmarking and personalized optimization for long-term stable operation.

The 990 PRO 4TB heatsink edition represents top-tier PCIe 4.0 storage capability for professional and enthusiast users. Its 7,450 MB/s ultra-fast read speed drastically reduces system boot, software launch, and AAA game loading delays. The 6,900 MB/s max write speed accelerates bulk transmission of 8K raw footage, massive game packages, multi-gigabyte project files and large backup archives, greatly improving daily workflow efficiency and gaming experience.

With upgraded 1.6 million random read IOPS, this high-capacity model delivers smoother system responsiveness during complex stacked workloads including video rendering, real-time streaming production, multi-software simultaneous operation, and background asset loading. The generous 4GB DRAM cache ensures stable low-latency output, while the integrated heatsink guarantees no performance degradation under sustained full-load operation.

Specially optimized for high-capacity Gen4 high-speed operation, the factory heatsink works with the nickel-coated controller to rapidly dissipate accumulated heat. This dual thermal solution effectively suppresses overheating and thermal throttling, maintaining consistent flagship performance in compact chassis, small-form-factor builds, and low-airflow workstations. The precisely tuned power architecture balances extreme performance and energy efficiency, ensuring stable power output during long-duration heavy tasks and lower power consumption during standby.

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

Hardware-accelerated AES 256-bit encryption realizes real-time full-disk encryption without occupying system resources or sacrificing speed. Multiple industry-standard security certifications fully meet personal and commercial data compliance requirements, ensuring safe and reliable data storage.

Featuring standard M.2 2280 form factor with factory heatsink, this SSD fits all mainstream M.2 NVMe slots on desktops, workstations and high-end laptops. It runs at full PCIe 4.0 speed on new-generation 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.
