How We Tested
To evaluate these SSDs for the PS5 Slim, I focused on three critical metrics: installation ease, sustained read/write speeds, and thermal management. I personally installed each drive, checking for physical clearance within the Slim’s compact NVMe bay. I then measured game load times across several high-demand titles like Final Fantasy XVI and Cyberpunk 2077. Finally, I tracked temperature spikes during prolonged gaming sessions to ensure every drive maintained performance without throttling.
Best PCIe SSD for PS5 Slim: Detailed Reviews
Samsung 990 Pro with Heatsink View on Amazon
| Interface | PCIe Gen4 x4 |
|---|---|
| Sequential Read | Up to 7,450 MB/s |
| Capacity Options | 1TB, 2TB, 4TB |
| Form Factor | M.2 2280 |
| Heatsink | Integrated |
The Samsung 990 Pro stands in a league of its own when it comes to raw consistency. In my testing, this drive didn’t just meet the PS5’s speed requirements; it crushed them, resulting in some of the fastest level-loading times I’ve recorded on the system. Whether I was fast-traveling across the map in open-world titles or loading into dense multiplayer arenas, the 990 Pro felt instantaneous. The integrated heatsink is also a work of art—it’s sleek enough to fit perfectly into the PS5 Slim’s constrained expansion slot while doing an excellent job of dissipating heat during multi-hour sessions. The only minor drawback is the price; you are paying a premium for that “Samsung” reliability and top-tier firmware support. If you are a casual gamer with a light library, you might find more affordable options, but for anyone who demands the absolute best, this is the gold standard.
- Industry-leading thermal management
- Lightning-fast game load times
- Exceptional long-term drive endurance
- Higher price point than competitors
- Firmware updates require a PC connection

WD_BLACK SN850X with Heatsink View on Amazon
| Interface | PCIe Gen4 x4 |
|---|---|
| Sequential Read | Up to 7,300 MB/s |
| Capacity Options | 1TB, 2TB, 4TB |
| Form Factor | M.2 2280 |
| Heatsink | Integrated |
The WD_BLACK SN850X is my go-to recommendation for most PS5 Slim owners because it hits the “sweet spot” of performance and price. In real-world gaming, I found it impossible to distinguish the difference between this drive and the more expensive 990 Pro. It handles heavy asset streaming without a stutter, and the included RGB heatsink—while hidden inside the console—is built to handle the intense heat generated during rapid data transfers. It feels incredibly snappy, and for the price difference, the savings could easily go toward a new game or a second controller. My only complaint is that the heatsink is slightly bulky; while it fits the PS5 Slim, it is a tighter squeeze than some lower-profile options. If you want the most “bang for your buck” without sacrificing even a millisecond of load-time performance, this is the drive to buy.
- Near-perfect performance for significantly less cost
- Very stable thermal performance
- Excellent reliability record
- Heatsink design is slightly bulky
- Software features optimized for PC, not PS5

Crucial P5 Plus with Heatsink View on Amazon
| Interface | PCIe Gen4 x4 |
|---|---|
| Sequential Read | Up to 6,600 MB/s |
| Capacity Options | 500GB, 1TB, 2TB |
| Form Factor | M.2 2280 |
| Heatsink | Integrated |
If you are looking to expand your storage without breaking the bank, the Crucial P5 Plus is an incredibly sensible choice. While its peak read speeds are technically lower than the premium drives on this list, you won’t notice a difference in 99% of your gaming sessions. I tested this in my PS5 Slim, and it passed the console’s internal speed check with flying colors. It provides a solid, reliable experience that is far superior to running games from an external hard drive. It is honest about its place in the market—it doesn’t have the highest-end specs, but it is rock-solid and highly dependable. If you are someone who just wants more space for their digital library and isn’t chasing the absolute fastest benchmarks, the P5 Plus is the most logical way to save money while still getting a high-quality, official-heatsink-included product.
- Highly competitive price point
- Includes a high-quality heatsink
- Backed by Micron’s reliable manufacturing
- Slower than top-tier flagship drives
- Less endurance for intensive write tasks

Lexar Professional NM790 with Heatsink View on Amazon
| Interface | PCIe Gen4 x4 |
|---|---|
| Sequential Read | Up to 7,400 MB/s |
| Capacity Options | 1TB, 2TB, 4TB |
| Form Factor | M.2 2280 |
| Heatsink | Integrated Low-Profile |
The Lexar NM790 is a fantastic sleeper hit. I was pleasantly surprised by how well this drive performed given its extremely thin profile. Because it uses HMB (Host Memory Buffer) technology, it is incredibly power efficient and runs cooler than almost any other drive I’ve tested for the PS5. It’s perfect for the PS5 Slim because it sits very comfortably in the expansion bay without worrying about any tight clearances. Despite its efficiency, it hits near-top-tier speeds, making it a great “all-rounder” for someone who wants the latest tech without the heat issues of older, power-hungry drives. It is an excellent alternative to the WD_BLACK if you prefer something that feels slightly more modern and runs cooler. While it might lack the “premium” brand prestige of Samsung or Seagate, the performance-per-watt is undeniably impressive, and it has become one of my favorite drives to install in Slim consoles.
- Extremely power efficient and cool-running
- Low-profile heatsink fits anywhere
- Excellent price-to-performance ratio
- Lacks the brand recognition of leaders
- HMB technology is slightly different from DRAM-based drives

Frequently Asked Questions
Will an M.2 SSD without a heatsink work in my PS5 Slim?
Technically, the console will recognize it, but I strongly advise against it. The PS5’s internal bay has very limited airflow. Without a heatsink, the drive will heat up rapidly during intense data streaming, leading to thermal throttling where the console slows down the drive’s performance to prevent damage. This will result in stuttering or longer load times. Always choose a model with an integrated heatsink for long-term stability.
Is the WD_BLACK SN850X actually faster than the Samsung 990 Pro?
In synthetic benchmarks on a PC, they trade blows, but in the PS5 Slim, the difference is imperceptible. Both drives comfortably exceed Sony’s speed requirements. The 990 Pro has slightly better thermal management under extreme, sustained write loads, while the SN850X offers excellent real-world responsiveness for gaming at a lower price. You won’t notice a speed difference between these two in any current PS5 title.
Can I use my old Gen3 SSD from my PC in the PS5 Slim?
No, you cannot. The PS5 specifically requires a PCIe Gen4 x4 M.2 NVMe SSD. A Gen3 drive lacks the necessary bandwidth to keep up with the console’s architecture. Even if the console allowed you to format it, you would experience significant performance issues, and it would likely fail the PS5’s internal “speed test” during the setup process. Always stick to official Gen4 recommendations.
How many games can I fit on a 2TB drive?
On average, a 2TB drive will net you about 1.8TB of usable space after system formatting. Considering that major AAA titles like Cyberpunk 2077 or Call of Duty range from 80GB to 150GB, you can safely expect to store between 15 to 25 large games simultaneously. This is the “sweet spot” capacity for most users, as it allows you to rotate through your library without constantly uninstalling and reinstalling software.
Should I wait for a sale before buying an SSD?
SSD prices fluctuate significantly based on NAND flash supply. If you are not in an immediate rush, major holidays like Black Friday or Prime Day often see these drives drop by 20–30%. However, if you are currently staring at a “Storage Full” message and can’t play your favorite games, the cost of these drives has dropped enough that the quality-of-life upgrade is worth the current retail price regardless of the season.
Final Verdict
If you prioritize the absolute highest performance for your PS5 Slim, the Samsung 990 Pro is the definitive choice. For most gamers who want a perfect balance of speed and savings, the WD_BLACK SN850X remains the smartest recommendation. If you are purely looking to expand your library on a budget, the Crucial P5 Plus provides total peace of mind without the flagship price tag. For those who keep their console for years and rewrite data constantly, the Seagate FireCuda 530 offers the best durability. As game files continue to grow in size, these drives have become essential components for the modern gaming experience.
