My chonky old PS5 is in dire need of a storage boost this Prime Day, and at 7 cents a GB it's time for an upgrade

I was able to traverse through the absolute minefield that was trying to get a hold of a PS5 right after launch, but that means I've been racking up trophies on the first model with its measly 825GB of storage.

As a result, I've been subject to a never-ending barrage of 'storage is full" notifications for years now, which is why I was thrilled when the best Prime Day PS5 deals kicked off this week. Finally, this was my chance to track down the best PS5 SSD deals so I could give my Sony pixel-pusher the storage it so desperately needs.

I write about PS5 accessories and SSDs for a living, so I already knew what drives to look out for, but for anyone new to the Sony storage world, it's not that simple.

For one, you need to ensure any PS5 SSD comes with a heatsink, that it's compatible with your model PS5, and you need to check that you're getting a model with enough storage that you'll actually use. To make finding the the best PS5 SSD this Prime Day less stressful, I've gathered all the drives I've been eyeing up down below.

How much PS5 SSD storage do you need?

The main decision you have to make when it comes to picking a PS5 SSD for your Sony console is how much storage is right for your gaming needs. Most modern AAA games are pretty storage demanding, so bigger is better, but not every single PS5 owner plays them.

What size is right for you is entirely dependent on what you play and whether or not you hate having to uninstall games to make room for more. For example, I love PS5 games of all kinds, from small indie releases like Crow Country to big-budget AAA masterpieces like Death Stranding 2, so having 4TB worth of space is ideal for me. I could get away with just picking up the 2TB Samsung 990 PRO SSD, but I also pay monthly for PlayStation Plus Premium, and would like to have that extra space to download and try out not just the latest monthly games, but all the new additions to the premium game catalog, too.

If that sounds like a familiar scenario, then 2TB and above are going to make more sense for your PS5. If you play a lot of online games like me, I'd also recommend grabbing at least an extra 2TB. I play Marvel Rivals, Fortnite, and Dead by Daylight, and like ensuring they're all at the ready for when my friends and I want to play - having at least 2TB or 4TB of storage will mean my console can keep the games installed, and deal with their upcoming data-heavy updates too.

If you already own the PS5 Slim with its 1TB of storage, or the PS5 Pro with its larger 2TB onboard storage, you can definitely make do with just another 1TB at your disposal. Grabbing just 1TB is always going to be the best budget-friendly option, whether Prime Day is happening or not, and it'll still give you more legroom for dealing with your favorite games' future DLC, patch updates and any extra screenshots and game clips you want to store and capture on your Sony console.

Ever since I first held a NES controller in my hand I've been obsessed with gaming, and the hardware it runs on. I could hook up a NES and SNES to a telly, without instructions, before I could walk. Even now, nothing is more exciting then taking a console, or handheld, out the box for the first time and setting it up. This obsession transformed into a love of games and game music, which lead to my music degree and dream of becoming the Scottish Nobuo Uematsu. After sharing my love of games through music, I began to share my love through words on sites like TechRadar and iMore. This lead to becoming a Hardware staff writer for PCGamesN, and later the Senior Tech Writer for Dexerto, covering all things Steam Deck, PlayStation and Nintendo. With that experience, I was able to level up as Hardware Editor for GamesRadar+, where I'm still just as Nintendo, PlayStation and gaming tech obsessed as ever.
