It's also officially licensed for PS5, and has a design that matches the console itself to keep your setup looking super slick.Today's best PS5 storage dealThis officially licenced external PS5 HDD from Seagate is the way to go if you want to upgrade your console storage right now. A quality 4TB PS5 SSD currently costs about £470, making this drive roughly a third of the price for more storage.View DealSo what makes a PS5 external hard drive different to a PS5 SSD? The main differentiator is that you can't play the PS5 games stored on an external hard drive directly. Instead, they need to be copied back to your internal storage for each use.It's perfect if you have slow internet speeds and want to avoid lengthy downloads when coming back to large games, which is mainly how I use the Seagate Game Drive hooked up to my own console.Backwards-compatible PS4 games are playable with no barriers, though, making this a very good choice for those with large libraries of older games they want to keep installed.More Prime Day deals in the UKAmazon Prime: sign up for a 30-day free trialAmazon Devices: Fire TV, Ring & Blink from £24.99Amazon Haul: up to 30% offApple: AirPods Pro 3 for a record-low priceAppliances: up to 45% off Ninja, Tefal & SageBeauty: up to 60% off Philips & Oral-BEssentials: household goods from under £10Fashion: up to 50% offHeadphones: up to 50% offLaptops: from £149.99Tablets: Samsung & Lenovo from £125Toys: up to 25% off Lego and ToniesTVs: from £129.99Vacuums: up to 40% off Eufy & RoborockWearables: Garmin & Huawei from £36.99
