Corsair has expanded its storage portfolio with the introduction of two new portable SSDs — the EX400U SURVIVOR USB4 External SSD and the EX300U USB External SSD. Both models are designed to meet the growing demand for fast, reliable, and flexible data storage across a wide range of devices, from desktop computers to mobile platforms.
The Corsair EX400U SURVIVOR takes advantage of the high bandwidth of USB4 technology, offering sequential read speeds of up to 4,000 MB/s and write speeds up to 3,600 MB/s. Built for durability, the EX400U SURVIVOR features an IP55-rated housing that provides resistance against dust, splashes, and impact. This design makes it well-suited for photographers, video editors, and professionals who often work on the move and need storage that can handle tough environments.
The drive works with USB4 and Thunderbolt 4 systems while maintaining backward compatibility with USB 3.2 Type-C interfaces. It also supports USB Type-C-equipped iPhones and iPads, offering plug-and-play operation without external power. The included 30 cm Type-C cable delivers both power and data transfer through a single connection, ensuring convenience during travel or fieldwork.
Available in 1 TB, 2 TB, and 4 TB capacities, the EX400U SURVIVOR comes with Corsair SSD Toolbox software, which provides secure erase functions, firmware updates, and performance monitoring options. Backed by a five-year limited warranty, the drive offers long-term reliability and access to Corsair’s customer support network, reinforcing its professional-grade build and dependability.
The second release, the Corsair EX300U USB External SSD, offers a compact and lightweight design focused on convenience and portability. With USB 3.2 Gen 2 Type-C connectivity, it delivers read and write speeds up to 1,100 MB/s, making it suitable for transferring photos, editing media files, or creating quick backups on the go.
One of its unique features is the MagSafe-compatible magnetic ring, allowing it to attach easily to iPhones or other magnetic surfaces. This feature provides flexibility for mobile content creators who need quick, reliable storage access during recording or data transfers. The EX300U supports Windows, macOS, iOS, and Android, ensuring broad compatibility across platforms.
Like the EX400U SURVIVOR, the EX300U supports the Corsair SSD Toolbox and comes with a three-year limited warranty. It is also available in storage capacities ranging from 1 TB to 4 TB, giving users flexibility based on their storage requirements.
Both models are available now through the Corsair webstore and authorized retailers and distributors worldwide. The EX400U SURVIVOR targets professionals and creators who need a rugged, high-performance storage solution, while the EX300U is positioned for users who value compactness, speed, and convenience.
