Complete Buying Guide for What Is The Best M.2 SSD For Gaming
Essential Factors We Consider
When choosing the best M.2 SSD for gaming, we focus on speed, capacity, compatibility, and thermal performance. Look for PCIe Gen4 or Gen5 support depending on your system, with read speeds above 7,000 MB/s for optimal gaming. Capacity should match your library size—2TB is the sweet spot for most users. Always check if your motherboard or console supports the drive’s interface, and consider a heatsink if space allows to prevent throttling.
Budget Planning
Prices vary widely: entry-level 1TB Gen4 drives start around $80, while high-capacity Gen5 models can exceed $300. Set a budget based on your needs—don’t overspend on speed you won’t fully utilize. For most gamers, a 2TB Gen4 SSD offers the best balance of performance, capacity, and value.
Final Thoughts
Upgrading to a high-quality M.2 SSD is one of the most noticeable improvements you can make to your gaming experience. Whether you prioritize speed, storage, or affordability, there’s a drive on this list that fits your needs. Invest wisely, and enjoy faster load times, smoother gameplay, and more space for your growing game collection.
Frequently Asked Questions
Q: What’s the difference between Gen4 and Gen5 SSDs?
A: Gen5 SSDs offer nearly double the bandwidth of Gen4, with speeds up to 14,000 MB/s vs. 7,000 MB/s. However, Gen5 requires compatible hardware and is currently overkill for most games—Gen4 remains the practical choice for most users.
Q: Can I use any M.2 SSD in my PS5?
A: No. The PS5 requires PCIe Gen4 M.2 SSDs with a heatsink and minimum 5,500 MB/s read speed. Always check Sony’s compatibility list before purchasing.
Q: Do I really need a heatsink on my SSD?
A: It depends. If your case has poor airflow or you play for long sessions, a heatsink helps prevent thermal throttling. For PS5 users, it’s almost mandatory.
Q: Will a faster SSD improve FPS in games?
A: Not directly. While a faster SSD reduces load times and improves asset streaming, it won’t increase frames per second. That’s handled by your GPU and CPU.
Q: How much storage do I need for gaming?
A: Modern AAA games can take 80–150GB each. We recommend at least 1TB for casual players and 2TB+ for serious gamers with large libraries.
