Complete Buying Guide for What M.2 SSD Should I Buy
Essential Factors We Consider
When deciding what M.2 SSD you should buy, focus on four key factors: interface (Gen3 vs Gen4), capacity, compatibility, and use case. Gen4 drives offer nearly double the speed of Gen3 but require compatible hardware. Capacity depends on your needs—500GB for basics, 1–2TB for gaming. Always check your device’s M.2 slot type (2280 is most common) and whether it supports NVMe (not SATA). Finally, consider if you need a heatsink, especially for PS5 or compact builds.
Budget Planning
Prices vary widely: Gen3 SSDs start around $40 for 1TB, while high-end Gen4 2TB models can exceed $150. Set a budget based on your performance needs. For most users, a 1TB Gen4 SSD offers the best balance of speed, space, and value. Don’t forget to factor in a heatsink if not included—it can add $10–$20 but prevents throttling.
Final Thoughts
Whether you’re building a new PC, upgrading an old laptop, or expanding your PS5, there’s an M.2 SSD on this list that fits your needs. Prioritize reliability, real-world performance, and compatibility over raw specs alone. Our top picks cover every scenario—from budget builds to high-end gaming rigs.
Frequently Asked Questions
Q: What’s the difference between PCIe Gen3 and Gen4 M.2 SSDs?
A: PCIe Gen4 SSDs are roughly twice as fast as Gen3, with read speeds up to 7,000MB/s vs 3,500MB/s. However, you need a Gen4-compatible motherboard or device to take advantage of the extra speed.
Q: Can I use any M.2 SSD in my PS5?
A: No—your PS5 requires a PCIe Gen4 NVMe M.2 SSD with a heatsink (or you must add one) and a minimum capacity of 250GB. Check Sony’s official compatibility list before buying.
Q: Do I need a heatsink for my M.2 SSD?
A: Not always, but highly recommended for Gen4 drives or compact builds. Heatsinks prevent thermal throttling during sustained workloads like gaming or video editing.
Q: Is 500GB enough for a gaming SSD?
A: It depends. Modern AAA games can take 100GB+ each, so 500GB fills up fast. We recommend at least 1TB for gamers.
Q: Are cheaper SSDs safe to use?
A: As long as they’re from reputable brands (even lesser-known ones like DATO or SIX), they’re generally safe. Avoid no-name brands with no reviews or specs.
