This article covers Seagate Expansion ポータブル 2.5インチ 【データ復旧 3年付】1TB 外付 ハードディスク HDD 3年保証 静音 PC Win Mac PS4 PS5 4K 対応 STKM1000400.

Overview

The Seagate Expansion Portable STKM1000400 is a 2.5-inch external hard drive offering 1TB of storage over USB 3.0. It is bus-powered, so no AC adapter is needed, making it highly portable. A standout feature is the included 3-year Rescue Data Recovery service, providing peace of mind for users who worry about accidental data loss. It is compatible with Windows, Mac, PS4, and PS5, offering broad flexibility. This drive sits at the entry-level to mid-range segment, prioritizing reliability and support over raw speed. The 1TB capacity is ideal for first-time external storage buyers or as a secondary backup drive.

Compatibility Guide

The drive connects via USB 3.0 (backward compatible with USB 2.0) and is supported on Windows 10/8/7, macOS, PlayStation 4, and PlayStation 5. It draws power from the USB port, so direct connection to a PC or console is recommended. Using a USB hub may cause power issues if the hub is unpowered. Form factor is 2.5-inch, similar to laptop hard drives. The included USB cable is 46 cm long, short enough to keep the drive close to the device.

Product Info

The Seagate Expansion STKM1000400 was released around 2021 and remains widely available. Key specs: 1TB capacity, USB 3.0 interface (5 Gbps max), 2.5-inch form factor, dimensions 115.3×80×12.6 mm, weight 257 g. The spindle speed is likely 5400 RPM. It comes with a 3-year limited warranty and 3-year Rescue data recovery service. Market positioning: entry-level external HDD with a premium support package that competitors rarely match at this price point.

Best Use Cases

First-time external drive buyers: Simple plug-and-play setup, no software needed. The included data recovery service removes the anxiety of potential drive failure. Console storage expansion (PS4/PS5): Works as backup storage for PS4 games and archive storage for PS5 games. Not suitable for playing PS5 games directly. Ultraportable backup for travelers: Lightweight and bus-powered, it fits easily in a laptop bag. Great for daily backups of documents and photos. Users wanting integrated data protection: The Rescue service covers both logical and physical failures, which is rare among budget external drives. ## Alternatives
Direct competitor: WD Elements Portable 1TB. Similar specs and price, but lacks the built-in data recovery service. If you value official recovery coverage, Seagate wins on value. Another alternative: Toshiba Canvio Basics 1TB. Also no standard recovery plan. Seagate's Rescue service adds significant value, especially if you store irreplaceable files.

Things to Consider

This is a spinning HDD, not an SSD. Sequential read/write speeds are around 120 MB/s, which is fine for documents and photos but slow for large media transfers or gaming loads. It is also physically fragile?handle with care during transport. 1TB may fill up quickly if you store many games or 4K videos. Consider the 2TB or 4TB variants if you need more space. The Rescue service excludes TV recordings and game saves, so verify the terms on Seagate's website. Also, the drive is factory-formatted as NTFS, requiring reformatting for full Mac compatibility. ## FAQ Q: Can I play PS5 games directly from this drive? A: No. PS5 games require the internal SSD or an NVMe SSD expansion. This drive works for storing PS5 games (you can copy them back to the internal SSD to play) and for PS4 games. Q: Do I need to format the drive for Mac? A: If you want read/write access on macOS, you'll need to reformat to exFAT or APFS (APFS is read-only on old macOS versions). NTFS works for reading only. Q: How do I use the data recovery service? A: Contact Seagate support, send the failed drive in a provided case, and they attempt recovery. Recovered data is returned via cloud storage at no extra cost during the 3-year period.
