Frequently Asked Questions
What's the best Barracuda for PS4?
The Seagate Barracuda 2TB 2.5″ (ST2000LM015) is the best choice. It's the maximum capacity that fits in PS4 (7mm height requirement). It quadruples your storage from the default 500GB or doubles the 1TB model.
Can I put a Barracuda inside my PS5?
No. PS5 uses a soldered internal SSD that cannot be replaced. For PS5 internal expansion, you need an NVMe SSD in the M.2 expansion slot. Barracuda can only be used as external USB storage with PS5.
Can I play PS5 games from a Barracuda external drive?
No. PS5 games can only be played from the internal SSD or NVMe expansion. You can store PS5 games on Barracuda to free up internal space, but must transfer them back to internal storage to play.
Will a 3TB or 4TB Barracuda fit in PS4?
No. The 3TB, 4TB, and 5TB 2.5″ Barracuda models are 15mm thick. PS4 requires 9.5mm or less. Only 7mm drives (up to 2TB) fit inside PS4. For more storage, use an external USB drive.
Is installing a Barracuda in PS4 difficult?
No, it's quite easy. You only need a Phillips screwdriver. The process takes about 15-20 minutes. The hardest part is downloading and setting up the system software on a USB drive before installation.
Will upgrading my PS4 drive void the warranty?
Sony officially supports user hard drive upgrades on PS4 - it does not void your warranty. The drive bay is designed for user access. This is different from PS5, where internal storage is not user-replaceable.
