Hey there, gamer! Is your PlayStation 5 storage starting to feel a bit cramped? With massive game installations becoming the norm, it’s no surprise that many PS5 owners are looking to expand their console’s capacity. And when it comes to reliable, high-performance M.2 SSDs, Lexar often makes a splash in online discussions. So, if you’re on the hunt for the Lexar best M.2 SSD for PS5 Reddit users are buzzing about, you’ve come to the right place!
We’ve delved into the specs, crunched the numbers, and even peeked at what the community’s saying to bring you a comprehensive guide to the top M.2 SSDs that’ll supercharge your PS5 experience. Let’s dive in!
Why Upgrade Your PS5 Storage?
Your PlayStation 5 comes with a speedy 825GB SSD, but only about 667GB is actually usable for games. That fills up fast! Upgrading your PS5 storage with an M.2 NVMe SSD offers a few sweet benefits:
- More Games: Store a massive library of titles without constantly deleting and redownloading.
- Faster Load Times: While the PS5’s internal SSD is quick, a compatible M.2 SSD can match or even exceed those speeds, ensuring seamless gameplay.
- Future-Proofing: As game sizes continue to grow, having ample storage will keep you ready for the next big releases.
Key Factors When Choosing a PS5 SSD
Before we jump into our top picks, here’s what you need to consider for your PS5 SSD upgrade:
- Form Factor: It must be an M.2 NVMe PCIe Gen4 SSD.
- Speed: Sony recommends a sequential read speed of at least 5,500 MB/s. Faster is always better!
- Capacity: Anywhere from 250GB to 8TB, but 1TB or 2TB is usually the sweet spot for most gamers.
- Heatsink: This is crucial! The PS5’s M.2 slot requires an SSD with an integrated heatsink or one you can attach yourself, to prevent overheating and maintain optimal performance.
- Physical Size: The SSD with its heatsink needs to fit within the PS5’s M.2 expansion slot dimensions.

FAQ Section
Q1: How do I install an M.2 SSD in my PS5?
A: Installing an M.2 SSD in your PS5 is fairly straightforward. You’ll need a Phillips head screwdriver. First, power down your PS5 and unplug all cables. Remove the console’s cover plates, locate the M.2 expansion slot (under a metal cover), insert the SSD at an angle, secure it with the screw provided with your PS5, replace the cover, and then reattach the PS5 cover plates. The PS5 will then prompt you to format the drive upon boot-up.
Q2: Do I need a heatsink for my PS5 M.2 SSD?
A: Yes, absolutely! Sony strongly recommends using an M.2 SSD with a heatsink to prevent thermal throttling and ensure consistent performance. Without one, your SSD could overheat, leading to reduced speeds and potential system instability during intense gaming sessions.
Q3: What are the minimum speed requirements for a PS5 SSD?
A: Sony recommends an M.2 NVMe PCIe Gen4 SSD with a sequential read speed of at least 5,500 MB/s. While some drives may technically work at lower speeds, meeting this recommendation ensures optimal performance and compatibility with your PS5 games.
Q4: Can I use any M.2 SSD with my PS5?
A: No. Your PS5 requires an M.2 NVMe PCIe Gen4 SSD. Older PCIe Gen3 drives or SATA M.2 SSDs are not compatible. Additionally, the SSD and its heatsink must fit within the specific dimensions of the PS5’s expansion slot. Always check the manufacturer’s compatibility list or product description.
Q5: What’s the difference between PCIe Gen4 and Gen5 for PS5?
A: PCIe Gen4 offers theoretical maximum speeds of around 7,000-7,500 MB/s, which the PS5 currently supports. PCIe Gen5 is the next generation, offering up to double those speeds (around 12,000-14,000 MB/s). While you can install a Gen5 SSD in your PS5, the console’s hardware currently limits it to Gen4 speeds. Investing in Gen5 is more about future-proofing for potentially updated PS5 firmware or future PC builds.
Q6: How much storage do I really need for my PS5?
A: It depends on your gaming habits. 1TB is a great starting point, allowing you to store 15-25 large games. 2TB is ideal for serious gamers who want a vast library without constant management. With some games reaching over 100GB, more space is always better if your budget allows.
Q7: Does installing an M.2 SSD void my PS5 warranty?
A: No, installing an M.2 SSD in the dedicated expansion slot of your PS5 does not void your warranty, as long as you follow Sony’s official installation instructions and don’t damage any components in the process.
