Get This Price

For just $243.05, down from its list price of $529.99, this 1TB USB4 drive undercuts its own recent pricing by a wide margin. The 30-day, 90-day, and 180-day averages all hover around $526 to $529, so this is a genuine anomaly in the price history rather than a routine fluctuation.

What You're Getting

The EX400U leans on USB4 to push sequential read speeds up to 4,000MB/sec and sequential write speeds up to 3,500MB/sec. That is enough headroom to move large video and photo files in seconds instead of minutes.

It connects over USB Type-C, Thunderbolt 4, and newer standards for broad compatibility across Windows PCs and Macs, and it supports MagSafe for easy attachment. The compact enclosure works plug-and-play out of the box with a single cable handling power and data.

Who This Is For

Best for video editors, photographers, and professionals who shuttle big files between a desktop and a laptop. Anyone running Thunderbolt or USB4 hardware will see the full speed benefit.

If you only need casual backup for documents and small files, a slower and cheaper drive gets the job done.

The Caveat

Full 4,000MB/sec throughput requires a USB4 connection. Older USB-C ports will still work but cap out at lower transfer rates, so check your machine before expecting top speeds.

Final Verdict

The 54% discount makes this the right moment to grab a 1TB USB4 drive if your workflow depends on fast external storage. At $243.05, the EX400U is a strong buy for creators who need portable speed today.
