Lexar JumpDrive Dual Drive D400

Expert Review Analysis

The Lexar JumpDrive Dual Drive D400 is a 128 GB USB flash drive featuring a swivel metal housing with both USB‑C and USB‑A connectors. It offers high read speeds up to 130 MB/s (tested up to 163 MB/s) and 256‑bit AES encryption for secure, cross‑platform file transfers.

✓ Best for: Cross‑device file transfers between USB‑C smartphones/tablets and legacy USB‑A computers, on‑the‑go professionals handling photos or presentations, travelers who need a compact, durable drive with keyring attachment, and users requiring built‑in encryption for data security.✗ Not ideal for: Users who prioritize maximum transfer speeds for large batch writes, those who need a low‑cost flash drive without premium metal housing, or anyone relying heavily on fast write performance for video recording or backup tasks.

Pros

✓Dual USB Type‑C and USB Type‑A connectors provide versatile compatibility across modern smartphones, tablets, and legacy computers.
✓Sturdy metal swivel housing with keyring loop enhances durability and portability for on‑the‑go use.

Flash Memory Sticks

High read performance consistently reaches or exceeds the advertised 130 MB/s, with independent tests showing up to 163 MB/s.

✓Built‑in 256‑bit AES encryption secures sensitive data when using Lexar DataShield software.

✓Simple formatting process allows the drive to be used on Android, PC, and Mac platforms without additional tools.

Cons

✗Write speed is considerably lower than read speed, averaging around 52 MB/s, which may slow large file transfers.
✗Limited consumer feedback and few user reviews make it difficult to assess real‑world reliability.
✗Maximum advertised read speed of 130 MB/s is lower than competing dual‑drive models that claim up to 400 MB/s.
✗No included software bundle or accessories beyond the drive itself, reducing perceived value for some users.
✗The metal case, while durable, adds slight bulk compared to ultra‑thin plastic alternatives.

From Expert Reviews

Praised by Experts

✓Professional reviewer Jason Bagnell highlighted the dual‑connector design as eliminating the need for adapters and praised its reliable high read speeds.
✓Reviewers from B&H Photo and Staples emphasized the tough metal construction and keyring loop as ideal for mobile professionals.
✓Editors noted the easy cross‑platform formatting and built‑in encryption as valuable security features.

Criticized by Experts

✗Reviewers pointed out the write speed of roughly 52 MB/s as a notable weakness compared to the read performance.
✗Some editors mentioned the lack of extensive user review data, making long‑term durability harder to verify.

Expert Opinion

Tech reviewers consider the Lexar D400 a solid, secure option for users who need a durable, dual‑connector flash drive. Its high read speeds and metal swivel design receive praise, while the relatively slow write performance and limited consumer feedback are noted as drawbacks.

What Users Say

Everyday user feedback is scarce; the few available sources provide no recurring praise or complaints, leaving professional testing as the primary source of insight.

Common Complaints

Write speed significantly lower than read speed (around 52 MB/s) and the scarcity of user reviews making long‑term reliability uncertain.

How It Compares

vs. SanDisk Ultra Dual Drive 128GB

Advantages

✓Higher advertised read speed up to 400 MB/s provides faster file access.
✓Similar dual USB‑C/USB‑A connector layout for cross‑platform use.

Disadvantages

✗No mention of built‑in encryption, reducing data‑security options.
✗Build details not specified, potentially less rugged than Lexar's metal swivel.

Choose SanDisk for maximum speed; choose Lexar for durability and encryption.

vs. SanDisk Ultra Dual Drive Go 256GB

Advantages

✓Larger 256 GB capacity for users needing more storage.
✓Advertised 400 MB/s read speed for rapid data retrieval.

Disadvantages

✗Lacks the 256‑bit AES encryption found in the Lexar model.
✗Build specifications are unclear, possibly less protective than Lexar's metal case.

Select the SanDisk Go model when capacity and speed dominate; select Lexar D400 when security and ruggedness are paramount.
