Corsair Unleashes the EX300U: A Magnetic Portable SSD Revolution with 4TB of Space


In a world where our smartphones have become the primary hubs for our digital lives, running out of storage is a modern-day nightmare. Whether you're a content creator drowning in 4K footage, a mobile gamer with a massive library, or simply someone who carries their entire photo collection with them, the struggle is real. Corsair, a leader in high-performance gear, has just unveiled a potential solution that blends massive capacity with ingenious convenience: the new EX300U Magnetic Portable SSD.

This isn't just another external drive. The Corsair EX300U is designed from the ground up for the wireless age, featuring seamless MagSafe compatibility and blistering speeds that promise to declutter your phone and supercharge your workflow.

Capacity and Pricing: Space for Everyone

Corsair is launching the EX300U in three distinct storage tiers, ensuring there's an option for every need and budget:

  • 1TB Model: Priced at an aggressive $99.99, this is the perfect entry-point for those looking to offload photos, videos, and apps without breaking the bank.
  • 2TB Model: For the power user, the $159.99 2TB variant offers ample space for extensive game libraries, professional creative projects, and comprehensive media backups.
  • 4TB Model: The new king of capacity, the top-tier 4TB model costs $324.99. This is the drive for professionals and data hoarders who need to carry an entire digital archive in their pocket.

The Magnetic Magic: Effortless Attachment for iPhone and Android

The headline feature of the EX300U is undoubtedly its magnetic attachment system. For iPhone users, it seamlessly snaps onto the back of MagSafe-compatible models, sitting snugly and securely without the need for cumbersome cases with built-in slots or awkward adhesive rings. This makes it incredibly easy to expand your iPhone's storage on the fly for a lengthy video shoot or a massive file transfer.

But Corsair hasn't forgotten about Android users. The company confirms that the EX300U is also compatible with the growing ecosystem of recent Android phones that support magnetic accessories. Furthermore, the drive will firmly attach to any metal surface, offering versatile mounting options on laptops, desks, or in a car.

For those looking to pair it with their iPhone, a MagSafe silicone case (currently $37 on Amazon) is a perfect companion for full functionality and protection.

Blistering Performance and Universal Compatibility

What good is all that space if it's slow? The EX300U is built for speed. Leveraging a USB Type-C 3.2 Gen 2 port, this portable SSD can achieve staggering sequential read and write speeds of up to 1,100 MB/s. This means you can transfer a 10GB 4K video file in a matter of seconds, not minutes.

The universal USB-C interface ensures it works flawlessly with a wide range of devices right out of the box, from modern smartphones and tablets to laptops and gaming consoles like the PlayStation 5 and Xbox Series X|S.

Thoughtful Design for a Mobile World

Corsair paid close attention to the user experience with several smart design choices. Inside the box, you'll find a USB-C to USB-C cable where one end has a 90-degree angle. This low-profile connection is perfect for attaching to a phone, as it lies flat and reduces strain on the port, preventing accidental bumps.

The drive itself is remarkably compact and lightweight, crafted to slip unnoticed into any pocket. Despite its sleek form factor, it doesn't sacrifice durability. The EX300U is shock-resistant, protecting your valuable data from the bumps and drops of daily life. For the 4TB model, Corsair backs it with a robust 1000 Terabytes Written (TBW) endurance rating, signaling strong long-term reliability.

Availability

The Corsair EX300U portable SSD is available for purchase now. The company has indicated that the first orders are expected to begin shipping out to customers starting October 10, 2025. For those who prefer the quick shipping and customer service of Amazon, the drive is also expected to be available through that platform shortly.

The launch of the EX300U solidifies Corsair's push into the mobile accessory space, offering a compelling, high-performance solution to one of the most persistent problems for modern device users. It’s more than just storage; it’s a seamlessly integrated expansion of your digital world.
