Corsair EX400U CSSD-EX400U2TB 2 TB

A flagship-class portable storage device aimed at professionals who value not only maximum performance but also convenience in everyday use. The model is equipped with a modern USB4 interface with Thunderbolt 4 support, enabling read speeds of up to 4000 MB/s and write speeds of up to 3500 MB/s, placing it among the fastest external SSDs on the market. At the heart of the Corsair EX400U is the high-performance Phison PS2251-18 controller, working in tandem with fast 3D TLC NAND memory using the NVMe protocol.

This combination ensures stable performance even during intensive data transfers, making the EX400U particularly attractive for editing 4K/6K video, working on large design projects, and backing up large volumes of data without speed loss. One of the model's key advantages is its support for USB4 and Thunderbolt 4, allowing the drive to work equally effectively with PCs, Macs, and modern tablets and smartphones running iOS and iPadOS.

Specifically, the drive officially supports Apple devices with iOS/iPadOS 13 and above, equipped with USB C, and features a MagSafe magnetic ring, allowing it to attach directly to the back of an iPhone—especially convenient for field use, shooting, or working without a stationary desk. The compact body is designed with a minimalist and functional aesthetic, maintaining a premium impression thanks to high-quality materials.

The device weighs 92 grams—enough to feel the reliability of the construction, yet easily fits into a pocket or accessory compartment. The 3-year warranty aligns with the professional solution segment, where reliability is critical. The 2 TB capacity makes the drive versatile: it easily handles both storing work projects and serving as extended fast storage for mobile and desktop devices.
