The Corsair EX400U is an excellent, compact and portable external SSD for gamers, creative professionals, and mobile users. With 2TB of space, you'll have plenty of storage for large program downloads, raw video files, photos, and more. And right now at Best Buy, you can pick one up for 62% off, bringing the price down to just $330 - one of the best external SSD discounts I've seen in a long time.

The EX400U connects to your Apple devices via USB-C and Thunderbolt 4 for blazing fast file transfers. You'll get read and write speeds up to 4,000 and 3,600 MB/s, respectively, for quicker offloading when you need to make room on your main storage drive. With plug-and-play compatibility, you can quickly and easily swap between your iMac, MacBook, and iPad when you need to change up your workflow. And with MagSafe, you can also use it with your iPhone for on-the-go content creation like vlogging and convention coverage.

The incredibly compact design makes it easy to tuck out of the way when not in use, and gives it a low profile when in MagSafe mode. And with a single connection for both data transfers and power, you won't have to worry about keeping track of multiple cables when doing on-location shoots or traveling. You can also use it with the Corsair SSD Toolbox program to keep an eye on your drive health, storage capacity, and upgrade firmware. The program also allows you to securely erase sensitive data to keep your personal details and work safe from unauthorized access.

How I rated this deal 

The cost of RAM and SSDs has skyrocketed in recent years, but discounts like this give hope that the bubble is finally popping. You'll get 2TB of storage, read speeds up to 4,000MB/s, write speeds up to 3,600MB/s, and Thunderbolt 4 compatiblility for ultra-fast data transfers when you need to offload programs and files to make room on your main drive. It also features MagSafe technology and iOS compatibility for use with iPads and iPhones. That's why I gave this deal a 5/5 Editor's rating.
