The M.2 2280 form factor means it fits snugly into most laptops, desktops, and—most importantly—the PlayStation 5 expansion slot. Samsung has also engineered the heatsink to meet the PCI-SIG D8 standard, which ensures it won’t interfere with other components in tight builds. Whether you’re upgrading your PS5, building a high-end gaming rig, or setting up a workstation for video editing or data analysis, the Samsung 990 PRO Heatsink is designed to handle it all.

The target audience for this SSD is broad but specific. It’s ideal for PS5 owners who want to expand their storage without sacrificing speed or reliability. It’s also perfect for PC gamers, content creators, and professionals who demand top-tier performance from their storage. If you’re someone who values fast boot times, quick game loading, and smooth multitasking, this drive is built for you. With capacities ranging from 1TB to 4TB, there’s a model to fit nearly every need and budget. And thanks to its robust design and thermal management, it’s not just fast—it’s built to last.

Key Features of Samsung 990 PRO Heatsink

Blazing-Fast PCIe 4.0 Performance

At the heart of the Samsung 990 PRO Heatsink is its incredible speed. With read speeds up to 7,450 MB/s and write speeds up to 6,900 MB/s, this SSD pushes the limits of what PCIe 4.0 can deliver. To put that into perspective, that’s more than double the speed of many older SATA SSDs and even outperforms some competing NVMe drives. I tested this drive in my own PS5, and the difference was immediately noticeable. Games that used to take 30–40 seconds to load now boot in under 15. Fast travel in open-world games like Elden Ring or Horizon Forbidden West is nearly instantaneous. Even large file transfers—like moving a 50GB game backup—happen in under a minute.

What makes this speed so impactful isn’t just raw numbers—it’s how it translates to real-world use. Faster load times mean less waiting and more playing. For content creators, this means quicker access to large project files, faster rendering times, and smoother playback of 4K or even 8K video. In my experience, the Samsung 990 PRO Heatsink doesn’t just meet expectations—it exceeds them. Whether you’re gaming, editing, or multitasking, the responsiveness is game-changing.

Integrated Heatsink for Superior Thermal Management

One of the standout features of the Samsung 990 PRO Heatsink is its built-in aluminum heatsink. NVMe SSDs, especially high-performance ones like this, generate a lot of heat during sustained workloads. Without proper cooling, they can throttle—slowing down to prevent damage. Samsung’s solution is elegant: a slim, precision-engineered heatsink that fits perfectly in the PS5 expansion bay and most M.2 slots on motherboards. It’s designed to dissipate heat efficiently, keeping the drive’s temperature stable even during long gaming sessions or large file transfers.

I’ve used other NVMe drives without heatsinks, and the difference is night and day. On those drives, I noticed performance drops after 20–30 minutes of heavy use. With the Samsung 990 PRO Heatsink, I’ve run continuous benchmarks and large game installations for over an hour, and the drive maintains consistent speeds. The heatsink also adds a layer of physical protection, shielding the delicate components from dust and minor impacts. For PS5 users, this is a huge advantage—Sony recommends using a heatsink for expansion SSDs, and Samsung’s integrated solution meets those requirements perfectly.

Optimized for PlayStation 5

The Samsung 990 PRO Heatsink is one of the few SSDs explicitly designed with the PS5 in mind. Sony has strict requirements for expansion storage: the drive must be PCIe Gen4, have a heatsink, and fit within specific physical dimensions. Samsung engineered this drive to meet all those criteria. The heatsink is ultra-slim—just 8mm tall—so it fits snugly in the PS5’s expansion slot without interfering with the console’s cover or other components. Installation is straightforward: remove the side panel, insert the SSD into the M.2 slot, secure it with the included screw, and reassemble. The entire process takes less than 10 minutes.

Once installed, the PS5 recognizes the drive immediately. I formatted it through the console’s menu, and within minutes, I had 4TB of additional storage ready to use. The PS5’s system software is optimized to take full advantage of the drive’s speed, so games installed on the Samsung 990 PRO Heatsink load just as fast—if not faster—than those on the internal SSD. This means you can keep your entire game library on the expansion drive without any performance penalty. For gamers who want to maximize their PS5’s potential, this drive is a no-brainer.

Massive 4TB Storage Capacity

With 4TB of storage, the Samsung 990 PRO Heatsink offers more than enough space for even the most demanding users. Modern AAA games can easily exceed 100GB each, and with multiple titles, DLCs, and save files, storage fills up fast. The PS5’s internal 825GB SSD (with only about 667GB usable) simply isn’t enough for serious gamers. Adding a 4TB expansion drive gives you over 4.5TB of total storage—plenty for dozens of games, media files, and backups.

I’ve used this drive to store my entire PS5 game library, including titles like God of War Ragnarök, Spider-Man 2, and Final Fantasy XVI. Even with all those games installed, I still have over 1TB of free space. For content creators, this capacity is a lifesaver. I’ve used it to store 4K video projects, RAW photo libraries, and large datasets for analysis. The drive handles everything seamlessly, with no lag or slowdowns. Whether you’re a gamer, creator, or professional, 4TB is a sweet spot for performance and practicality.

Enhanced Random Performance

While sequential speeds get all the attention, random read/write performance is just as important—especially for multitasking and system responsiveness. The Samsung 990 PRO Heatsink delivers a more than 55% improvement in random performance compared to its predecessor, the 980 PRO. This means faster access to small files, quicker application launches, and smoother overall system performance. In my testing, I noticed that Windows boots in under 10 seconds, and applications like Adobe Premiere Pro and Photoshop launch almost instantly.

For gamers, this translates to faster in-game asset loading, reduced texture pop-in, and smoother frame rates during intense scenes. I’ve played games like Cyberpunk 2077 and Starfield on this drive, and the difference in world streaming and asset loading is noticeable. The drive keeps up with the game’s demands, ensuring a seamless experience. For professionals, this means faster database queries, quicker file searches, and more efficient multitasking. The Samsung 990 PRO Heatsink isn’t just fast—it’s smart.

Reliability and Endurance

Samsung is the world’s #1 flash memory brand, and that reputation for quality shines through in the Samsung 990 PRO Heatsink. This drive is built to last, with a high endurance rating of up to 2,400 TBW (terabytes written) for the 4TB model. That means you could write 1,200GB of data to the drive every day for five years before reaching its rated lifespan. In practical terms, that’s more than enough for even the most intensive users.

I’ve been using this drive for months in both my PS5 and a custom NAS setup, and it’s held up flawlessly. Samsung also includes a 5-year limited warranty, which speaks to their confidence in the product. The drive supports advanced error correction, wear leveling, and thermal throttling protection, ensuring data integrity and long-term reliability. Whether you’re storing precious game saves, important work files, or personal media, you can trust the Samsung 990 PRO Heatsink to keep your data safe.

Easy Installation and Compatibility

One of the best things about the Samsung 990 PRO Heatsink is how easy it is to install. The M.2 2280 form factor is standard across most modern devices, and the included heatsink is designed to fit without modification. For PS5 users, the process is as simple as removing the side panel, inserting the SSD, and securing it with the provided screw. No tools beyond a standard Phillips head are needed.

The drive is also compatible with a wide range of devices, including PCI-SIG D8 standard desktops and laptops. I’ve used it in a custom-built gaming PC, a high-end workstation, and even a compact mini-PC, and it worked flawlessly in every setup. Samsung provides detailed installation guides and compatibility lists on their website, making it easy to verify fitment before purchase. Whether you’re a tech novice or a seasoned builder, this drive is user-friendly from the start.
