Buying Guide: What to Look For in a PS5 External SSD
Not every external SSD works well with the PlayStation 5. You need a drive that meets specific requirements for speed, form factor, and reliability. Here are the key factors we consider.
Speed and Interface
The PS5 supports USB 3.2 Gen 2 and Gen 2×2 for external drives. A faster interface means quicker load times and smoother transfers. For PS4 games, any SSD with read speeds above 500 MB/s will feel snappy. For archiving PS5 games, the drive must be at least USB 3.0, but we recommend USB 3.2 Gen 2 or Gen 2×2 for the best experience. The Western Digital 1TB P40 Game Drive SSD, for instance, reaches up to 2,000 MB/s with its USB 3.2 Gen 2×2 interface, making it one of the fastest options available.
Capacity and Value
Storage needs vary. A 1TB drive can hold around 10 to 15 modern titles, while a 2TB drive doubles that. The BUFFALO External SSD 1TB offers a solid balance of price and performance for budget-conscious gamers. If you need more space, the SanDisk 2TB Extreme Portable SSD provides ample room for a large library. Consider how many games you keep installed at once and whether you prefer a lower upfront cost or maximum capacity.
Durability and Portability
External drives travel with you. A rugged design protects against drops and dust. The SanDisk Extreme is rated for 3-meter drop protection and IP65 water/dust resistance, making it ideal for LAN parties or travel. The WD_BLACK P40 survives drops up to 2 meters. The BUFFALO SSD also features a shock-resistant build. If you frequently move your drive between consoles or PCs, prioritize durability.
