When it comes to the performance of the best phones, one of the least talked-about specs is the storage speed. According to a new rumor, Samsung could leverage the latest UFS 4.1 speeds for the upcoming Galaxy S25 Ultra, which would offer a considerable performance bump compared to the Galaxy S24 Ultra.
The UFS 4.1 leak comes from a tipster named Sawyer Galox on X. While Galox isn't the most renowned leaker yet, the leak makes sense from a logical perspective. Most Galaxy S24 models featured UFS 4.0, so it would only make sense for Samsung to upgrade to the newer standard with the S25. The X post only specifies that the Galaxy S25 Ultra will get faster speeds, so we'll have to wait until closer to the launch to determine if the other S25 models will see the upgrade or if it's locked to the most expensive phone.
The speed offered by UFS 4.1 is reported to be incremental over UFS 4.0, though we'll have to wait until something is officially announced before we know for sure. We know UFS 5.0 is coming in 2027, so we expect 4.1 to serve as more of a stopgap than a game-changing speed upgrade. For perspective, UFS 4.0 offers write speeds of up to 4200MB per second compared to UFS 3.1's 1,200MB per second.
It's also worth noting that there were rumors that the Galaxy S24 would get UFS 4.1, but that didn't happen.
