Unfortunately, you're mostly paying for the brand name there. The PS4 Pros USB ports bottleneck the Samsung T7 1TB USB 3.2 SSD so you wont see those advertised speeds. I was pretty disappointed when my Crucial X8 1TB Portable SSD performed exactly like a budget drive on my own console. Honestly, just grab the Crucial X6 1TB Portable SSD and save your money. It'll still slash those open world load times for you.

I spent ages researching because I was worried about losing my game saves. Buying the Samsung T7 1TB Portable SSD made me feel a lot better and I'm really happy with it. It's been totally reliable for my open world stuff.

• Samsung T7: Runs quiet and stays cool.
• Crucial X8 1TB Portable SSD: Good value but feels less sturdy. The T7 isnt actually faster on a Pro, just feels like a safer choice tbh.

Building on the earlier suggestion, I unfortunately had issues with the Samsung T7 1TB Portable SSD because it gets throttled way too much. It was not as good as expected for the price. Just grab a Crucial BX500 1TB 3D NAND SATA SSD and an enclosure. Honestly my console fan sounds like a jet engine lately. My cat actually hides when I play... anyway, go cheap.
