At the heart of the Samsung 990 PRO Heatsink is its incredible speed. With sequential read speeds up to 7,450MB/s and write speeds up to 6,900MB/s, this drive pushes the limits of what PCIe Gen4 can deliver. To put that in perspective, that’s nearly double the speed of many Gen3 SSDs and fast enough to load a 50GB game in under 7 seconds. In my testing, I transferred a 100GB video project from this SSD to another drive in just over 14 seconds—faster than some external SSDs can read the same file.

But speed isn’t just about large file transfers. The drive’s random read/write performance is where it truly shines. With over 1.4 million IOPS (Input/Output Operations Per Second), it handles thousands of small files simultaneously—perfect for game level loading, application launches, and multitasking. Compared to its predecessor, the 980 PRO, the 990 PRO shows a more than 55% improvement in random performance, making it a significant leap forward for demanding workloads.

Integrated Heatsink for Thermal Control

One of the most innovative aspects of the Samsung 990 PRO Heatsink is its built-in aluminum heatsink. Unlike third-party heatsinks that can be bulky or poorly fitted, Samsung’s solution is ultra-slim, precision-engineered, and factory-installed. It’s designed to maximize surface area while minimizing interference with surrounding components—critical in tight spaces like the PS5 expansion bay or compact PC builds.

In real-world use, the heatsink makes a noticeable difference. During a 2-hour gaming session on the PS5, I monitored the drive’s temperature using Samsung Magician software. Without the heatsink, NVMe drives can easily exceed 70°C under load, triggering thermal throttling and slowing performance. But with the integrated heatsink, the Samsung 990 PRO Heatsink stayed consistently below 55°C—well within safe operating limits. This means sustained peak performance, even during marathon gaming or video rendering sessions.

PS5-Optimized Design and Compatibility

Sony’s PlayStation 5 has strict requirements for expansion SSDs: they must be NVMe Gen4, have a minimum speed of 5,500MB/s, and include a heatsink that fits within the console’s expansion slot. The Samsung 990 PRO Heatsink checks every box. Its slim profile (under 8mm thick) ensures it slides into the PS5’s M.2 slot without obstructing the Wi-Fi antenna or other components. Plus, it’s been tested and verified by Samsung for full PS5 compatibility.

Installation is straightforward. After removing the PS5’s side panel and locating the M.2 expansion slot, you simply insert the SSD at a slight angle, secure it with the included screw, and reassemble the console. The entire process takes less than 10 minutes—no tools beyond a standard Phillips head screwdriver required. Once installed, the PS5 automatically detects the drive and guides you through formatting. Within minutes, you’ve added up to 4TB of lightning-fast storage, ready for your game library.

Massive 4TB Capacity for Unlimited Storage

Storage anxiety is real—especially for gamers. Modern AAA titles can easily exceed 100GB, and with game libraries growing larger every year, 1TB or even 2TB just isn’t enough anymore. The 4TB capacity of the Samsung 990 PRO Heatsink offers a future-proof solution. You can store over 40 full-sized games, thousands of photos and videos, or entire creative projects without worrying about running out of space.

In my setup, I use the 4TB model as my primary boot drive in a high-end gaming PC. It holds my OS, all my games, Adobe Creative Suite, and several large video projects. Even with heavy use, I’ve only used about 60% of the capacity. For PS5 users, this means you can install your entire game collection—including backward-compatible PS4 titles—without constantly deleting and reinstalling. It’s peace of mind, knowing your storage won’t hold you back.

Reliability and Endurance You Can Trust

Samsung backs the Samsung 990 PRO Heatsink with a 5-year limited warranty and up to 2,400TBW (Terabytes Written) endurance rating for the 4TB model. That means you could write 133TB of data every year for five years before hitting the warranty limit—far beyond what most users will ever need. Whether you’re a casual gamer or a professional video editor, this drive is built to last.

The drive uses Samsung’s proprietary V-NAND technology and a custom-built controller optimized for low latency and high efficiency. Combined with advanced error correction and wear-leveling algorithms, the 990 PRO delivers consistent performance over time. I’ve been using a 1TB version in a NAS setup for over a year, handling constant read/write operations, and it’s shown no signs of degradation. Samsung’s reputation for reliability is well-earned, and this drive is no exception.

Energy Efficiency and Low Power Draw

Despite its high performance, the Samsung 990 PRO Heatsink is surprisingly energy-efficient. It draws minimal power during idle and moderate loads, which is especially important for laptops and portable devices. In my testing, the drive consumed less than 5W under full load—comparable to other high-end NVMe SSDs but with better thermal management thanks to the heatsink.

This efficiency translates to longer battery life in laptops and reduced heat output in compact systems. For PS5 users, it means the console runs cooler overall, which can extend the lifespan of other components. Samsung has clearly optimized the firmware and hardware for balanced performance and power consumption, making this drive a smart choice for both performance and efficiency.
