Why SSD Type Matters for Gaming
Not all SSDs are equal for gaming. The performance differences between storage generations are substantial, and choosing the right interface and drive significantly impacts load times, open-world streaming, and future compatibility.
SATA SSD: The slowest SSD type, connecting via the same interface as traditional hard drives. Sequential read speeds of approximately 550 MB/s. While dramatically faster than HDDs (which max out around 150-200 MB/s), SATA SSDs are bottlenecked by the SATA interface.
NVMe PCIe Gen 3: Connects directly to the CPU via PCIe lanes, bypassing the SATA bottleneck. Sequential read speeds of 3,000-3,500 MB/s — 5-6x faster than SATA. This is the minimum recommended storage for new gaming builds in 2025.
NVMe PCIe Gen 4: Doubles Gen 3 bandwidth with sequential reads of 5,000-7,000 MB/s. Required for PS5 SSD expansion. Meaningfully faster than Gen 3 for open-world games with heavy asset streaming.
NVMe PCIe Gen 5: The newest generation, with sequential reads up to 12,000-14,000 MB/s. Current gaming titles do not yet fully utilize this bandwidth, but Gen 5 drives are future-proof investments.
The practical gaming reality: For most current games, the difference between SATA and Gen 3 NVMe is noticeable. The difference between Gen 3 and Gen 4 is smaller in everyday gaming but significant for DirectStorage-enabled titles. Gen 5 provides negligible gaming benefit over Gen 4 in 2025.
Best NVMe SSDs for Gaming in 2025
Best Overall: Samsung 990 Pro
Interface: PCIe Gen 4 NVMe Sequential Read: 7,450 MB/s Sequential Write: 6,900 MB/s Available capacities: 1 TB, 2 TB, 4 TB Price: $90-180 depending on capacity
The Samsung 990 Pro is the gaming SSD benchmark for good reason. It combines the highest Gen 4 sequential speeds available with industry-leading random performance (critical for game loading) and Samsung's exceptional reliability track record. The drive runs cool enough that a heatsink is often unnecessary, though including one does not hurt.
For PS5 users, the 990 Pro meets PlayStation's speed requirements and fits the PS5's M.2 slot (with the optional heatsink). It is Sony's own informal recommendation for PS5 expansion.
Best for: Gamers who want the fastest, most reliable Gen 4 SSD without paying Gen 5 prices.
Best Budget: WD Blue SN580
Interface: PCIe Gen 4 NVMe Sequential Read: 4,150 MB/s Sequential Write: 4,150 MB/s Available capacities: 250 GB, 500 GB, 1 TB, 2 TB Price: $55-100
Western Digital's Blue SN580 is a remarkable value: Gen 4 speeds (more than adequate for any current game) at budget Gen 3 pricing. The performance is meaningfully below the 990 Pro, but the practical gaming experience difference is minimal for most titles.
For budget gaming builds or secondary drive purchases, the SN580 delivers excellent bang-for-buck.
Best Gen 4 Value: Seagate FireCuda 530
Interface: PCIe Gen 4 NVMe Sequential Read: 7,300 MB/s Sequential Write: 6,900 MB/s Available capacities: 500 GB, 1 TB, 2 TB, 4 TB Price: $80-200
The FireCuda 530 competes directly with the Samsung 990 Pro for the top Gen 4 spot. Sequential performance is nearly identical. Seagate includes a heatsink version which is essential for the PS5 (PS5's M.2 slot requires a heatsink). The heatsink version is often slightly better value than the 990 Pro for PS5 users.
Best Gen 5: WD Black SN850X / Crucial T705
Interface: PCIe Gen 5 NVMe Sequential Read: 12,000-14,500 MB/s Price: $130-250
For future-proofing enthusiasts, Gen 5 drives provide headroom for next-generation DirectStorage titles and workloads. Current gaming does not fully utilize this bandwidth, making Gen 5 an investment in future performance rather than an immediate gaming upgrade.
The WD Black SN850X and Crucial T705 are the leading Gen 5 options. Both require Gen 5-capable motherboards (current AMD X670/B650 and Intel Z790 series) — verify compatibility before purchasing.
Best for PS5: Samsung 990 Pro with Heatsink
Why heatsink matters: The PS5's M.2 slot requires a heatsink on the installed drive to ensure proper cooling. You can purchase a third-party heatsink separately or buy drives that include one. The Samsung 990 Pro comes in a heatsink version purpose-designed for PS5 compatibility.
PS5 speed requirement: Sony requires a minimum 5,500 MB/s read speed for PS5 M.2 expansion. Any Gen 4 drive on this list meets that requirement. Gen 3 drives do not.
PS5 capacity: The PS5 uses about 667 GB of its 825 GB total storage for games (system files consume the rest). Adding a 1-2 TB NVMe drive essentially doubles your game library capacity.
Best SATA SSD: Samsung 870 EVO
Interface: SATA Sequential Read: 560 MB/s Available capacities: 250 GB to 4 TB Price: $50-200
While Gen 3 NVMe is the recommended minimum for new gaming builds, SATA SSDs remain useful for secondary storage, older systems limited to SATA, and cost-effective large-capacity storage. The Samsung 870 EVO is the SATA benchmark — the most reliable, consistently performing SATA drive available.
Use cases: secondary storage for less-played games, older laptops upgrading from HDD, systems with occupied M.2 slots.
How Much SSD Storage Do You Need for Gaming?
Modern games have expanded dramatically in size:
- Call of Duty: Modern Warfare III: 200+ GB
- Microsoft Flight Simulator: 100+ GB
- Red Dead Redemption 2: 150+ GB
- Baldur's Gate 3: 150 GB
- Cyberpunk 2077: 70 GB
A library of 10-15 major titles easily fills 1 TB. For a comfortable gaming setup that does not require constantly uninstalling games:
- 1 TB: Minimum for a gaming-only drive; workable but requires management
- 2 TB: The sweet spot for most gamers — room for 15-25 major titles plus the OS
- 4 TB: Future-proof; sufficient for large libraries without management
Given current SSD pricing (2 TB Gen 4 NVMe available for $100-120), 2 TB is the recommended starting point for new builds.
Installing an NVMe SSD
NVMe installation is straightforward:
- Identify your M.2 slot location on your motherboard (consult manual)
- Remove the M.2 retaining screw
- Insert the drive at a slight upward angle into the slot
- Press down and secure with the retaining screw
- For PS5: attach the heatsink before or after installation per heatsink instructions
For gaming PCs, initialize and format the new drive in Windows Disk Management, or use your motherboard's storage utility during setup.
