This article covers Seagate (シーゲイト) ポータブル 2TB 外付け ハードドライブ HDD.

Overview

Seagate's Portable 2TB External Hard Drive (STGX2000400) is a compact, USB 3.0-powered storage solution designed for easy backup and file transfer across Windows, Mac, PlayStation, and Xbox. With a simple drag-and-drop interface, it requires no software installation, making it ideal for anyone who wants a hassle-free backup drive.
This drive offers 2TB of storage capacity, enough for thousands of photos, hours of video, or a large game library. The USB 3.0 interface provides up to 5Gbps transfer speeds, significantly faster than USB 2.0, though real-world performance will vary depending on the file type and system.
Positioned as an entry-level external HDD, it competes with other 2.5-inch portable drives from WD, Toshiba, and others. Its key differentiator is the included 1-year Rescue data recovery service, which adds peace of mind for users concerned about data loss.

Compatibility Guide

Connection is via USB 3.0 Micro-B. The included 18-inch cable is sufficient for desktop use, but for laptop users, a longer cable may be helpful.
Supported operating systems: Windows 7 and later, macOS 10.12 and later. It also works with PlayStation 4, PlayStation 5 (as external storage for PS4 games and PS5 game backup), Xbox One, and Xbox Series X|S (as external storage for games).
The drive ships formatted as exFAT, which is natively read/write on both Windows and macOS without additional drivers. For console use, the console will prompt to format the drive, which will erase all data.
USB 2.0 ports are supported via backward compatibility, but speeds will be limited to USB 2.0 (480Mbps).

Product Info

The Seagate Portable 2TB (STGX2000400) was released around 2020 and remains widely available. As of 2026, the street price in Japan is approximately ¥23,000 on online retailers. It carries a 1-year limited warranty and includes 1 year of Rescue data recovery services.
Market positioning: Entry-level portable HDD. The 2TB capacity and USB 3.0 interface meet the needs of average home users, while the Rescue service provides a safety net that many competitors lack. It's not the fastest or most rugged drive, but it's a reliable, cost-effective choice for basic backup.

Best Use Cases

① Users new to external storage

  • Plug-and-play simplicity: no software to install, just connect and start copying files.
  • Ideal for students, seniors, or anyone who just wants a simple backup drive.
  • Not suitable for users who need blazing-fast transfer speeds or who plan to edit video directly from the drive.
    ② Console gamers expanding storage
  • Works with PS4/PS5 and Xbox One/Series X|S for storing games and media.
  • Good for storing PS4 games and moving them between consoles, or for archiving older games.
  • PS5 native games cannot be played from an external USB drive; they must be on the internal SSD or an expansion slot NVMe drive. This is a hardware limitation of the console, not the drive.
    ③ Budget-conscious backup for photos and media
  • 2TB at a low price point is hard to beat for bulk storage of photos, music, and documents.
  • No recurring cloud subscription fees.
  • Not ideal for frequent travelers; HDDs are susceptible to shock damage during transport.

Things to Consider

This is a traditional hard disk drive, not an SSD. Expect significantly slower performance for random access and file transfers compared to any external SSD. If you regularly move large files (e.g., 4K video projects), an external SSD will save you time.
The drive uses a USB 3.0 Micro-B connector, which is becoming less common. The included cable is short (18 inches). If your PC tower is under the desk, you may need a longer cable or a USB extension. Also, modern laptops often have only USB-C ports, so you may need a USB-C to Micro-B adapter or cable.
While the 1-year Rescue service is a nice bonus, it's not a substitute for a proper backup strategy. Always keep at least two copies of important data, ideally in different physical locations.

FAQ

Q: Can I use this drive with both Windows and Mac without reformatting?
A: Yes, it comes pre-formatted in exFAT, which is supported by both Windows and macOS for reading and writing. No additional drivers are needed.
Q: Does this work with PlayStation 5?
A: Yes, for PS4 games and to store PS5 game backups. However, PS5 native games cannot be played directly from an external USB drive; they must be on the internal SSD or an NVMe expansion slot.
Q: How long does the 1-year Rescue service cover, and what happens after it expires?
A: The Rescue data recovery service is active for 1 year from the date of purchase. After that, if the drive fails, you would need to use a third-party data recovery service or rely on your own backups. The drive itself continues to function normally after the service period.
