This article covers Seagate disque dur Ext. 2.5インチ 1TB 拡張 USB3 STEA1000400 3428。 .
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.
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.
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.
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.
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. Also, note that the 1TB capacity may fill quickly if you store large media libraries.
Q: Can I use this drive with a PlayStation or Xbox? A: Yes, it works with PS4, PS5 (for PS4 games and media), and Xbox One/Series X|S for storing games and apps. Note that PS5 games cannot be played directly from an external HDD. Format as exFAT for cross-platform use. Q: Does it come with any software? A: Yes, Seagate Dashboard is included for automatic backup scheduling. It's compatible with Windows and macOS. * Q: Is it silent? A: Idle noise is minimal, but you'll hear seek sounds during access. In a quiet room, it may be noticeable. Consider a fanless SSD if absolute silence is required.
