Read Speed: 7,000 MB/s
Capacity: 4TB
Technology: PCIe Gen4 x4
Warranty: 5 years
The fanxiang 4TB Gaming SSD addresses a common complaint among PS5 owners: capacity limitations. I spent four weeks testing this drive, and having 4TB of additional storage completely changed how I manage my game library. No longer do I need to delete games to make room for new releases, which is a genuine quality-of-life improvement.
Performance is solid with 7,000 MB/s read speeds and 6,000 MB/s write speeds, which comfortably exceeds PS5 requirements. In real-world use, I noticed no difference in load times between this drive and more expensive competitors. Games installed on the fanxiang loaded just as quickly as those on internal storage, including large open-world titles.
The heatsink design is effective and well-suited for PS5 use. During my testing, temperatures remained consistent even during extended gaming sessions. I tested this in both the original PS5 and PS5 Slim models, and it fits perfectly in both consoles with the included heatsink.
What gives me confidence is the 5-year warranty and lifetime technical support. While fanxiang isn't as established a brand as Samsung or WD, the warranty coverage suggests they stand behind their product. The drive is also compatible with DirectStorage on PC, making it versatile if you plan to use it for gaming beyond your PS5.
Perfect for gamers with massive game libraries who never want to delete games again. If you play multiple AAA titles simultaneously and want the convenience of keeping everything installed, 4TB is a game-changer. Also ideal for households with multiple PS5 users or anyone tired of constant game management.
You prefer established brands with proven track records, or if you don't need 4TB of storage. Also, if you use Mac computers and want to repurpose the drive later, note that it's not Mac OS compatible. Gamers who only play a few titles at a time might be better served by smaller, faster options.
Not every SSD will work with your PS5, and understanding the requirements is crucial before making a purchase. Sony has set specific technical standards that must be met for a drive to function properly as storage expansion. Let me break down exactly what you need to look for.
The minimum requirement is 5,500 MB/s sequential read speed, but I recommend aiming for 6,500+ MB/s for future-proofing. Your SSD must be PCIe Gen4 x4 with NVMe 1.4 support. Older Gen3 drives won't work, regardless of their advertised speeds. The interface is fundamental to achieving the bandwidth needed for PS5 gaming performance.
Form factor is another critical consideration. Your PS5 accepts M.2 2230, 2242, 2260, and 2280 sizes, but 2280 is the most common and recommended. The drive must physically fit in the expansion bay, and some longer drives may not work in the PS5 Slim due to space constraints. Always verify dimensions before purchasing.
Heatsink requirements are non-negotiable. Your PS5 will reject drives without adequate thermal management, and for good reason. The internal bay has limited airflow, and drives can quickly overheat without proper cooling. Some drives come with integrated heatsinks, while others require you to purchase one separately.
Capacity options range from 250GB to 4TB, with 1TB and 2TB being the sweet spots for most gamers. Smaller capacities fill up too quickly given modern game sizes, while 4TB options are expensive. Consider your gaming habits when choosing capacity. If you play multiple large titles simultaneously, 2TB or more is worth the investment.
One technical detail that often confuses buyers is the difference between DRAM cache and Host Memory Buffer (HMB) technology. Both serve similar purposes but achieve them through different methods. Understanding this helps you make informed decisions, especially when comparing budget and premium SSDs.
DRAM cache is physical memory on the SSD that stores frequently accessed data for faster retrieval. Drives with DRAM, like the Samsung 990 PRO and WD_BLACK SN850X, deliver more consistent performance even when nearly full. They're particularly better at handling random read/write operations, which impacts things like texture streaming in games.
HMB technology, used in drives like the Lexar NM790, uses system RAM to simulate DRAM cache. This approach reduces manufacturing costs, resulting in more affordable drives. In real-world PS5 gaming, the difference between DRAM and HMB is minimal for most users. You might notice slight differences in specific scenarios, but general gaming performance is very similar.
The choice between DRAM and HMB comes down to budget and use case. If you're a competitive gamer who needs every advantage, DRAM drives offer more consistent performance. If you're a casual gamer looking for value, HMB drives provide excellent performance-per-dollar. Both technologies work perfectly with PS5 storage expansion requirements.
Installing an SSD in your PS5 might seem intimidating, but it's actually straightforward. I've installed drives in multiple PS5 consoles, and each time took less than 15 minutes. Follow these steps carefully, and you'll have expanded storage in no time.
First, power off your PS5 completely and unplug all cables. Place the console on a clean, static-free surface with the bottom facing up. You'll need a Phillips #1 screwdriver, which is typically included with compatible SSDs. Ground yourself by touching a metal surface to prevent static damage.
Remove the PS5's base stand if attached. On the original PS5, unclip the cover by lifting the small lever near the HDMI port and sliding the cover off. For PS5 Slim, remove the side panel by pressing the release clips. You'll see the M.2 expansion slot cover with a screw holding it in place.
Remove the expansion slot cover screw and set it aside with the cover. Inside, you'll see the thermal spacer and the M.2 slot itself. Remove the screw from the standoff, as you won't need it. Your SSD should come with a longer screw and a spacer washer if needed.
Insert your SSD into the M.2 slot at a slight angle, with the chips facing toward you. Gently push until the drive is fully seated in the connector. Lower the drive into place and secure it with the mounting screw. Don't overtighten, just make it snug. Replace the expansion slot cover and screw it back in place.
Reattach your PS5's outer cover or side panel, reconnect all cables, and power on your console. Navigate to Settings > Storage > Extended Storage and follow the on-screen prompts to format your new SSD. This process takes a few minutes and will prepare the drive for PS5 use. Once complete, you can set this as your default installation location for games.
Choosing the right capacity depends on your gaming habits and budget. Modern PS5 games range from 50GB for indie titles to over 200GB for AAA releases. The PS5's internal storage offers about 667GB of usable space, which stores roughly 5-10 games depending on their sizes.
1TB drives are ideal for casual gamers who play 3-5 titles at a time. This adds room for approximately 5-7 additional PS5 games or 15-20 PS4 games. It's the most budget-friendly option for getting started with storage expansion. However, you may still need to manage your library occasionally as newer games continue to increase in size.
2TB drives represent the sweet spot for most gamers. This capacity doubles your potential game library to roughly 10-15 PS5 titles or 30-40 PS4 games. You'll rarely need to delete games, making it much more convenient. The price-per-GB is also better than 1TB options, making it a good long-term investment.
4TB drives are ideal for hardcore gamers, collectors, and households with multiple PS5 users. This massive capacity allows you to store 20+ PS5 games or 60+ PS4 games, essentially eliminating storage concerns entirely. However, these drives are expensive and represent diminishing returns for casual players.
Consider your gaming patterns when choosing. If you frequently replay games or have a large library of titles you want installed, opt for 2TB or more. If you only play a couple of games at a time and don't mind managing storage, 1TB will suffice. Remember that you can always add additional drives later if your needs change.
After extensively testing all these options, the best SSDs for PS5 storage expansion in 2026 offer something for every budget and use case. The Samsung 990 PRO remains my top overall pick for its combination of speed, reliability, and thermal performance. If you want guaranteed compatibility and official certification, the WD_BLACK SN850P is worth the premium. Budget-conscious gamers will find excellent value in the Lexar NM790 without sacrificing meaningful performance.
Remember that all the drives recommended here meet or exceed PS5 requirements, so you can't go wrong with any choice on this list. Consider your budget, gaming habits, and long-term plans when making your decision. A 2TB drive from a reputable brand with a good heatsink and 5-year warranty represents the sweet spot for most PS5 owners looking to expand their storage in 2026.
External SSDs remain a viable alternative for PS4 games if you want to preserve your internal M.2 slot for PS5 titles only. This strategy can help you maximize value and storage efficiency. Whichever option you choose, expanding your PS5 storage will transform your gaming experience by giving you the freedom to keep your entire library ready to play at all times.
