How We Tested
To evaluate these drives, I installed each into a PS5 console and measured real-world load times across three graphically demanding titles. I focused on thermal stability, using a thermal probe to monitor heat spikes during sustained data transfers. Across 12 different models, I scrutinized compatibility with the Sony M.2 guidelines, ease of installation, and long-term data endurance, ensuring that the heatsink designs fit perfectly within the narrow console expansion slot without causing airflow issues.
Best PCIe SSD for PS5: Detailed Reviews
Samsung 990 Pro with Heatsink View on Amazon
| Interface | PCIe 4.0 x4 |
|---|---|
| Max Read Speed | 7,450 MB/s |
| Capacity | Up to 4TB |
| Heatsink Included | Yes |
| Warranty | 5-Year Limited |
The Samsung 990 Pro is currently the gold standard for PS5 expansion. In my testing, I noticed near-instantaneous asset loading in open-world games like Horizon Forbidden West. The drive runs impressively cool thanks to the integrated, sleek-looking heatsink that fits perfectly under the PS5’s standard cover. Whether you are transferring 500GB of games from the internal drive or playing directly off the expansion, the responsiveness remains identical to the stock SSD. It excels in heavy, sustained read cycles, making it the most reliable choice for a “set it and forget it” upgrade. One minor limitation is the price point; it consistently demands a premium over competitors. If you are looking for the absolute peak of performance and reliability, this is the one to get. Those on a strict budget who only play occasionally may find this overkill for their needs.
- Fastest sequential read speeds in class
- Low-profile heatsink fits perfectly
- Excellent drive health monitoring software
- Highest cost per gigabyte among top tier
- Packaging is surprisingly minimal
WD_BLACK SN850X with Heatsink View on Amazon
| Interface | PCIe 4.0 x4 |
|---|---|
| Max Read Speed | 7,300 MB/s |
| Capacity | Up to 4TB |
| Heatsink Included | Yes |
| Warranty | 5-Year Limited |
The WD_BLACK SN850X is my go-to recommendation for anyone who wants high-end performance without the high-end tax. During my tests, the SN850X stayed neck-and-neck with more expensive drives during standard gameplay, and I honestly couldn’t tell the difference in load times between this and the 990 Pro. It has a robust, aggressive design that looks like it belongs in a gaming machine. It handles large file transfers reliably, which is great if you use your console to store your entire game library. While it lacks the absolute benchmark-topping numbers of our best overall pick, it offers arguably the best value for your hard-earned cash. It occasionally runs a few degrees hotter than the Samsung in extreme, hour-long load tests, but this never affected actual gameplay framerates or stability. If you want a top-tier experience for significantly less money, this is the drive for you. Skip this only if you need a specific, niche drive for PC-exclusive workstation tasks.
- Exceptional real-world gaming performance
- Frequently on sale
- Highly reliable under heavy loads
- Heatsink adds slightly more bulk
- Can run warmer during massive transfers
Crucial P5 Plus with Heatsink View on Amazon
| Interface | PCIe 4.0 x4 |
|---|---|
| Max Read Speed | 6,600 MB/s |
| Capacity | Up to 2TB |
| Heatsink Included | Yes |
| Warranty | 5-Year Limited |
If you just want more space to store your games and don’t care about the absolute fastest benchmark numbers, the Crucial P5 Plus is an excellent choice. During my testing, I found it perfectly capable of handling the demands of modern PS5 titles, and it never caused a system stutter or crash. It is significantly more affordable than the high-end drives, making it a great way to double your storage without breaking the bank. The included heatsink is sturdy and simple to mount, giving me peace of mind about thermal throttling. While it is slower on paper than the 990 Pro, the difference in game loading is measured in mere seconds—something I barely noticed in daily use. If you are a casual player who isn’t obsessing over load times, this drive is more than sufficient. You should skip this if you are a power user who frequently transfers huge files, as the lower write speeds may become noticeable over time.
- Excellent price point for Gen4 speed
- Very stable performance in my testing
- Simple, effective design
- Slower read/write speeds than top-tier
- Limited to 2TB capacity
Lexar Professional NM790 with Heatsink View on Amazon
| Interface | PCIe 4.0 x4 |
|---|---|
| Max Read Speed | 7,400 MB/s |
| Capacity | Up to 4TB |
| Heatsink Included | Yes |
| Warranty | 5-Year Limited |
The Lexar NM790 is a fantastic, underrated powerhouse. What sets it apart for me is how it manages to deliver high-end 7,400 MB/s read speeds while running remarkably efficiently. Because it consumes less power, it tends to run cooler than many of its competitors, which is perfect for the cramped, thermally-sensitive environment inside the PS5 expansion slot. In my testing, I found the drive to be snappy and consistent, handling everything from quick-resume tasks to massive game updates without breaking a sweat. It is a very clean, well-engineered drive that often flies under the radar compared to the big-name brands. If you value efficiency and want a drive that is technically modern, this is a brilliant choice. It doesn’t have the marketing weight of Samsung or WD, which means you might find it on sale more often. Skip this only if you prefer brands with decades of established reliability in the high-end gaming space, as Lexar is still building its reputation in the enthusiast SSD market.
- Extremely power efficient
- Excellent thermal performance
- Great competitive pricing
- Brand recognition is less than Samsung/WD
- Availability can fluctuate

Frequently Asked Questions
Can I use an SSD without a heatsink in my PS5?
Technically, the console will recognize it, but I strongly advise against it. Sony explicitly mandates a cooling solution because these high-speed Gen4 drives generate significant heat. Running one without a heatsink will force the drive to throttle its speed to prevent permanent damage, causing noticeable stuttering in open-world games. Always opt for a model with an integrated heatsink or attach a low-profile third-party one to maintain optimal performance.
Is the WD_BLACK SN850X significantly better than the Crucial P5 Plus?
For the average gamer, the difference is negligible during standard play. The SN850X boasts faster raw speeds and superior sustained performance for file transfers, which matters if you are constantly moving hundreds of gigabytes of data. However, the P5 Plus is more than capable of keeping up with PS5 game asset loading requirements. If you value top-tier performance for the next few years, the WD drive is the better investment; if you just want extra space, choose the P5 Plus.
What is the biggest mistake people make when buying a PS5 SSD?
The most common error is ignoring the physical dimensions of the drive. The PS5 M.2 slot is narrow and has a specific screw-hole placement. Some SSDs come with oversized, “bulky” heatsinks that physically won’t fit under the console’s metal cover. Always verify that your chosen drive is “PS5 compatible” or specifically designed to fit within the M.2 expansion slot’s height limits to avoid a return nightmare.
Will a 4TB drive affect my PS5 performance compared to a 1TB drive?
No, the capacity does not dictate speed. In fact, many 4TB versions of the same SSD series perform slightly better due to increased over-provisioning and more NAND flash channels. The only difference is the price and your ability to store more games at once. Your console’s load times will remain identical regardless of whether you are using a 1TB or 4TB drive, provided they are the same model and interface generation.
Should I wait for a sale before buying an SSD for my PS5?
SSD prices fluctuate wildly based on NAND supply cycles. If you aren’t currently hitting your storage limit, it is absolutely worth waiting for major retail events like Prime Day or Black Friday. These drives frequently see 20-30% discounts. However, if you are currently deleting games to make room for new releases, the convenience of having your entire library accessible at once is usually worth the current market price.
Final Verdict
If you want the absolute best, the Samsung 990 Pro is your winner; it offers the most robust performance for demanding titles. For those seeking the sweet spot, the WD_BLACK SN850X is the most balanced choice for price-to-performance. Budget-conscious gamers should look no further than the Crucial P5 Plus, which provides all the necessary speed for a fraction of the cost. If you are a professional user or heavy data-mover, the endurance of the Seagate FireCuda 530 is unmatched. As storage requirements for games continue to skyrocket, opting for at least a 2TB drive is now the smartest way to future-proof your console.
