When it comes to best phone performance, 1 of the least talked about specifications is storage speed. According to new rumors, Samsung will be able to leverage the speed of the latest UFS4.1 for the upcoming Galaxy S25Ultra, which will give it a considerable performance boost compared to the Galaxy S24Ultra.

The UFS4.1 leak comes from a tipster named Sawyer Galox of X.Galox is not the most famous leaker yet, but the leak makes sense from a logical point of view. Most Galaxy S24 models were powered by UFS4.0, so it makes sense for Samsung to upgrade to the new standard on the s25. X post only specifies that the Galaxy S25Ultra will be faster, so you'll have to wait until it gets closer to launch to determine if you see an upgrade on the other S25 models or if it's locked on the most expensive phone.

Faster specifications are needed across the board, as Samsung pushes AI capabilities on many devices to its phones. That means your phone will need better RAM, faster processors and, of course, faster storage. As more leaks occur, more detailed images begin to appear about how Samsung will respond to additional performance needs, but UFS4.1 seems like a good step.

The speed provided by UFS4.1 is reported to increase more than ufs4.0, but you have to wait until something is officially announced. We know UFS5.0 will be coming in 2027, so we expect UFS4.1 to act as a stopgap rather than a game-changing speed upgrade. For outlook, UFS4.0 offers write speeds of up to 3.1MB/s, compared to ufs1,200, 4200MB/s.

It's also worth noting that there were rumors that the Galaxy S24 would get UFS4.1, but that didn't happen. 

AI will be the main beneficiary of the increase in speed, as common day-to-day tasks that require SSDs are already performed incredibly quickly. However, for the purpose of AI, the faster you read and write, the faster you can get the data you need for your algorithm, so the faster it responds and generates. For example, services like real-time language translation can see benefits from extra speed.
