This article covers Lexar D70E 1TB デュアルドライブ 外付けSSD 最大2.

Overview

The Lexar D70E 1TB Dual Drive Portable SSD brings a cable-free experience to external storage with its built-in USB-C and USB-A connectors. It delivers read speeds up to 2000MB/s and write speeds up to 1800MB/s when connected to a USB 3.2 Gen 2x2 port, making it ideal for fast file transfers and backups. Its metal housing weighs just 55g, ensuring easy portability. Compatible with a wide range of devices including PCs, Macs, tablets, and smartphones (including iPhone 17), this drive targets mobile professionals and content creators who need quick, adapter-free connectivity.

Compatibility Guide

The D70E integrates dual USB-C and USB-A connectors directly into the drive, eliminating the need for separate cables. For full 2000MB/s performance, the host device must support USB 3.2 Gen 2x2 (20Gbps). Most current laptops and desktops with USB-C ports run USB 3.2 Gen 2 (10Gbps), which will cap speeds around 1000MB/s over USB-C. When using the USB-A connector, maximum read and write speeds are 1000MB/s and 900MB/s respectively. It works with Windows, macOS, iOS, and Android devices out of the box, typically formatted as exFAT.

Product Info

Launched in 2025, the Lexar D70E is a mid-to-high-range portable SSD available in 1TB and 2TB capacities. The 1TB model retails around ¥54,000 in Japan. Lexar offers a 3-year limited warranty. Its standout feature is the dual-connector design, which positions it as a convenient solution for users who frequently switch between USB-C and USB-A devices without carrying extra cables.

Best Use Cases

  • Mobile professionals juggling laptops and smartphones: The cable-free design allows you to plug into a MacBook for work files, then directly into an iPhone or Android tablet for media offload without any adapters. A potential drawback is the exposed connector when not in use, so a protective case is recommended.
  • Content creators and photographers: With read speeds up to 2000MB/s, transferring large RAW image files or 4K video clips is noticeably faster than typical 10Gbps SSDs. The compact metal body withstands everyday bumps. However, the TBW rating is not disclosed, so for extremely heavy write workloads (e.g., constant video recording), a drive with a published endurance rating might be safer.
  • Tablet and smartphone storage expansion: Users with newer USB-C devices can directly attach the D70E for extra space. This is especially handy for iPhone 17 users who often struggle with limited internal storage. Note that some apps may restrict access to external storage, so check compatibility beforehand.

Things to Consider

The D70E's maximum speed is only achievable with a USB 3.2 Gen 2x2 host port, which is still not ubiquitous on many PCs and Macs – most laptops only support 10Gbps USB 3.2 Gen 2. Without Gen 2x2, you're limited to roughly half the advertised speed. The undisclosed TBW may be a concern for high-write applications. Compared to rivals like the Samsung T7 Shield (which offers IP65 water/dust resistance and a known 5-year warranty) or SanDisk Extreme Pro, the D70E's main advantage is its integrated dual connectors, but it lacks official ingress protection. The connector is not retractable, so care is needed during transport to avoid damage. Also, the price per GB is slightly higher than some competitors with similar sequential speeds.

FAQ

Q: Can I use the USB-C and USB-A connectors at the same time?
A: No, the drive has a single built-in connector that switches between USB-C and USB-A. You can only connect one device at a time.
Q: Does it work with game consoles like PlayStation 5 or Xbox Series X?
A: Yes, as a USB mass storage device. On PS5 you can play PS4 games and store PS5 game data, but cannot play PS5 games directly from the external drive. Xbox allows game storage and play for selected titles.
Q: Is the drive compatible with Apple's iPhone 17?
A: Yes, the USB-C connector plugs directly into iPhone 17 for file transfers and backups using the Files app or Lexar's companion app.
