Corsair’s EX400U is a compact external SSD that delivers blazing-fast USB4 speeds in a portable, simple design. It’s one of the best we’ve ever tested in terms of speed and storage space.
And right now, the Corsair EX400U 2TB is down to $300 (was $330) at Best Buy as part of the Tech Fest sale that ends Sunday.
This capacity gives you plenty of space for large files, backups, and creative projects. It is ideal for anyone who regularly works with high-resolution media or large data sets.

In our review, storage expert Mark praised it, saying it “delivers the performance I was hoping for. Such a huge jump in speed over Gen 2 or even Gen2x2 that it’s impossible to ignore.”
These read speeds reach up to 4,000 MB/s, while write speeds reach up to 3,600 MB/s, making file transfers fast and efficient. Moving large video files or project folders won’t slow you down.
The USB4 interface keeps things fast and future-ready, while the USB-C connection makes it easy to use with modern laptops, tablets, and other devices.
Its small size and lightness make it easy to carry in a pocket or bag. At less than an ounce, it’s barely noticeable when you’re on the go.
Power comes directly from the USB port, so you don’t need an external adapter or additional cables. This simplicity makes it ideal for travel or quick setups.
Besides Windows and macOS, it works with Apple iOS and iPadOS devices, providing flexibility if you move files between different platforms.
For anyone who needs fast, portable storage without the added bulk, this is a clean, high-performance option that accommodates demanding workflows.
However, as we noted in our review: “Without a USB 4.0 port, it’s a completely useless purchase. It will work with USB 3.2, but only at much slower speeds.”
