Best SSD for PS5 Storage Expansion in 2026
Direct-answer intro (30-80w)
The best SSD for PS5 storage expansion in 2026 combines fast PCIe Gen4 speeds, reliable performance, and compatibility with Sony’s M.2 slot requirements.
Editorial intro (~280w): PS5 M.2 slot specs (Gen4 x4, 5500 MB/s min, heatsink required)
Sony’s PlayStation 5 supports internal storage upgrade via an M.2 slot accepting PCIe Gen4 x4 NVMe SSDs with minimum sequential read speeds of 5500 MB/s. A heatsink is mandatory to prevent thermal throttling during gaming sessions.
Given these requirements, not every SSD on the market qualifies. Choosing an SSD with an integrated or aftermarket heatsink and sticking to form factors 2230 through 22110 maximizes compatibility.
Our top picks focus on delivering high-speed performance, while maintaining the PS5’s thermal envelope requirements. Cost, capacity, and ease of installation are also key considerations for most users.
5-column comparison table
| Pick | Best For | Key Spec | Price Range | Verdict |
|---|---|---|---|---|
| WD SN550 1TB | Best Overall | PCIe Gen3, 2.4GB/s read | $80-90 | Reliable performance with Gen3 fallback |
| Samsung 870 EVO 500GB | Best Value | SATA 2.5", compatible extern | $50-60 | Great for external storage but slower |
| Crucial BX500 1TB | Best for Capacity | SATA 2.5", 1TB storage | $60-70 | Affordable entry-level, decent capacity |
| SanDisk Ultra 3D 1TB | Best Performance | SATA 2.5", consistent speed | $80-100 | Good balance of price and performance |
Best Overall: WD SN550 1TB (note: Gen3 fallback discussion + alternative)
While the WD SN550 is PCIe Gen3, it remains a solid choice for the PS5 due to Sony’s allowances for Gen3 drives as fallback options. It offers sequential reads of around 2400 MB/s, providing decent loading speeds and reliability.
For users seeking higher Gen4 performance, upgrading later to Gen4 drives such as the WD Black SN850 is possible.
Best Value: Samsung 870 EVO 500GB (external use case)
The Samsung 870 EVO SATA SSD is ideal for users who want an external solution augmenting their PS5 storage. With USB 3.2 Gen2 or Gen1 external enclosures, it provides good value and durability for media storage, though it won’t match the NVMe speeds inside the console.
Best for Capacity: Crucial BX500 1TB
An affordable choice offering large capacity for PS5 storage expansion where raw speed is not the absolute priority. Suitable as a secondary backup or game library expansion.
Best Performance: SanDisk Ultra 3D 1TB
The SanDisk Ultra 3D blends reliability with solid performance, suitable for consistent game loading and installs. It maintains good thermal performance with a heatsink.
Budget Pick: Best entry-tier configuration
Entry-level PS5 storage users can find suitable options in cost-effective SATA or lower-tier NVMe models, balancing price and capacity for light use.
What to look for (Gen4, sequential read, heatsink, DRAM cache)
- PCIe Gen4 x4 interface for best speeds
- Sequential read speeds of 5500 MB/s or higher
- An integrated or aftermarket heatsink for thermal management
- DRAM cache for consistent performance
FAQ (5 Q&A, 60-100w each)
