This article covers Seagate disque dur Ext. 2.5インチ 1TB 拡張 USB3 STEA1000400 3428。.

Overview

The Seagate STEA1000400 is a 2.5-inch external hard drive from Seagate's Expansion series. With 1TB of storage and USB 3.0 connectivity, it offers a straightforward plug-and-play solution for backup and extra capacity. Its compact design and bus-powered operation make it highly portable. This is an entry-level external HDD that prioritizes simplicity and reliability over speed.

Compatibility Guide

This drive uses a USB 3.0 interface and is backward compatible with USB 2.0. It works with Windows, macOS, and Linux without additional drivers. The 2.5-inch form factor draws power directly from the USB port, eliminating the need for an external power adapter. However, ensure you connect to a USB 3.0 port or a high-power USB 2.0 port to avoid insufficient power issues.

Product Info

The Seagate STEA1000400 was released around 2019 and typically retails for around $50–$60 (2026). It comes with a 1-year warranty. The internal drive is a Seagate 2.5-inch SATA HDD, achieving up to 120 MB/s sequential read/write speeds over USB 3.0. It sits in the entry-level segment of external storage, offering a balance of cost and capacity for basic backup needs.

Best Use Cases

Budget backup solution: Ideal for users who want an easy, low-cost way to back up documents, photos, and media. The included Seagate Dashboard software enables scheduled backups. Not suitable for frequent heavy file transfers. Extra storage for laptops: Lightweight and bus-powered, it's a convenient companion for ultrabooks or Chromebooks with limited internal storage. Avoid using it as a primary drive for running applications. * File transfer between computers: USB 3.0 provides decent speed for moving large batches of files. However, for repeated large transfers, an SSD or USB 3.2 Gen 2 drive would be faster. If you need high-speed random access for gaming or professional video editing, consider an external SSD instead.

Things to Consider

The STEA1000400 is a mechanical HDD, so it's slower and more fragile than SSDs. Avoid dropping it, especially during operation. Real-world transfer speeds hover around 100 MB/s, which is fine for backups but not for demanding workloads. Competing products like the WD Elements Portable offer similar performance at a comparable price. Also, note that the 1TB capacity may fill quickly if you store large media libraries. ## FAQ
