Cons
From Expert Reviews
Praised by Experts
Criticized by Experts
Best For
Mobile content creators – particularly iPhone users who need to record 4K video directly to external storage; travelers and professionals requiring fast, portable storage for large files; cross‑platform users working between Windows, macOS, and iOS; gamers and media editors needing rapid game or video file transfers; tech enthusiasts who value component transparency and high‑speed USB4 connectivity.
Not Ideal For
Users who require ruggedized, shock‑ or water‑resistant drives; those needing built‑in hardware encryption for security; customers whose primary need is maximum sequential write speed at the USB4 theoretical limit; owners of early AMD‑based USB4 systems that may exhibit compatibility issues.
Expert Opinion
Professional reviewers praise the EX400U for its groundbreaking combination of ultra‑compact size, USB4‑native performance, and the unique MagSafe magnetic base that lets iPhone users record 4K video directly to the drive. Reviewers highlight its fast 4,000 MB/s reads, strong sustained writes, and the value‑for‑money price, earning it multiple Editors’ Choice accolades. The main criticisms focus on write speeds that don’t fully exploit USB4’s ceiling, a modest endurance rating, and the absence of encryption or rugged features.
What Users Say
Everyday users (as inferred from expert testing that mirrors real‑world use) appreciate the drive’s blistering transfer speeds, especially for large 4K video files, and its pocket‑sized form factor that fits easily in a laptop bag. They also like the seamless iPhone attachment for on‑the‑go recording. Common concerns revolve around the slightly lower-than‑advertised write speeds, the lack of a protective case, and worries about durability and encryption for sensitive data.
Common Complaints
Write speeds not reaching the advertised 4,000 MB/s peak; lower endurance (250 TBW per TB) than many competing TLC SSDs; absence of hardware encryption and ruggedized casing; no included travel pouch; occasional incompatibility on early USB4 platforms, especially some AMD implementations.
How It Compares
vs. Lexar Professional Go Portable SSD With Hub
Advantages
Disadvantages
Choose Lexar if you need a hub and ProRes support and can accept slower USB 3.2 speeds; otherwise the EX400U offers faster USB4 performance and larger capacities.
vs. LaCie Rugged SSD4
Advantages
Disadvantages
Select LaCie Rugged SSD4 when durability is paramount; for speed, portability, and iPhone compatibility, the EX400U is the superior option.
