This article covers Seagate (シーゲイト) ゲーム用ドライブ Xbox用 500GB SSD 外付け ソリッドステートドライブ ポータブル USB 3.0.

Overview

Seagate's Game Drive for Xbox (STHB500401) is an officially licensed external SSD designed specifically for Xbox One consoles. With 500GB of storage capacity and a USB 3.0 interface, it offers a straightforward way to expand your game library while significantly reducing load times compared to the internal hard drive. The package also includes a 2-month Xbox Game Pass membership, giving you immediate access to over 100 titles. This portable SSD is bus-powered, meaning it draws power directly from the Xbox's USB port — no separate power adapter needed. Setup is truly plug-and-play: just connect it to any USB port on your console, and the Xbox will automatically recognize and format the drive. The compact, black enclosure matches the design language of the Xbox One X and is built to withstand minor bumps and drops. Positioned as an entry-level storage expansion for Xbox gamers, this drive is ideal for those who have filled their internal storage and want a quick, affordable upgrade. It's not the fastest or largest external SSD on the market, but for its intended audience, it delivers exactly what's needed without unnecessary complexity.

Compatibility Guide

The Game Drive for Xbox is compatible with Xbox One, Xbox One S, Xbox One X, and Xbox Series X|S (for backward-compatible titles only via USB). It uses a USB 3.0 (USB 3.1 Gen1) interface and is also backward-compatible with USB 2.0, though performance will be limited. The drive is a 2.5-inch form factor external SSD, so it's not intended for internal installation. For Xbox Series X|S users, it's important to note that this USB-connected drive cannot run Series X|S optimized games at full speed. To play those titles with the fastest load times, you'll need Seagate's proprietary Storage Expansion Card that plugs into the console's internal expansion slot. This Game Drive is best used for storing and playing Xbox One, Xbox 360, and original Xbox games on your Series X|S. The drive also works with Windows PCs, but you'll need to reformat it to NTFS or exFAT before use. When switching between Xbox and PC, remember that reformatting erases all data.

Product Info

The Seagate Game Drive for Xbox 500GB (STHB500401) launched around 2018 and has since seen price reductions. As of 2025, it typically retails for around $50–60 USD or ¥5,000–6,000 JPY. It comes with a 1-year limited warranty and includes 1 year of Seagate Rescue Data Recovery Services, which can be a lifesaver if the drive fails. Market positioning is firmly entry-level. It's a purpose-built accessory for Xbox gamers who want a simple, no-fuss storage upgrade. The 500GB capacity is modest by today's standards, but the combination of official licensing, plug-and-play setup, and bundled Game Pass membership makes it a compelling value proposition for its target audience.

Best Use Cases

Xbox One owners running out of space: If your internal drive is full and you're tired of deleting games to make room, this SSD gives you 500GB of extra space. Load times for games stored on the SSD will be noticeably faster than from the internal HDD. New Xbox Game Pass subscribers: The included 2-month membership is a great way to dive into the service without an upfront commitment. You can immediately download and play games from the Game Pass library directly to the SSD. Gamers who attend LAN parties or travel: The compact, lightweight design and bus-powered operation make it easy to bring your game library to a friend's house. No need to carry a power brick. However, this drive is not ideal for: Xbox Series X|S owners wanting full-speed native titles: For the fastest loading of Series X|S optimized games, you need the internal expansion card. This USB SSD is limited to backward-compatible titles. Gamers with massive libraries: 500GB fills up quickly with modern AAA titles. If you play more than 4–5 large games regularly, consider a 1TB or 2TB model. Users who need a fast internal PC drive: This is an external USB drive, not an internal SATA or NVMe SSD. Performance will be limited by the USB 3.0 interface.

Things to Consider

While the Game Drive for Xbox is a solid choice for its intended use, there are a few caveats. First, the 500GB capacity is quite limited by 2025 standards. A single game like Call of Duty: Modern Warfare II can take up over 150GB, leaving room for only 2–3 other large titles. If you have a broad game library, you'll likely need to manage storage more actively. Second, the USB 3.0 interface caps sequential read/write speeds at around 400–500 MB/s in ideal conditions. This is still much faster than the Xbox One's internal HDD (around 100–150 MB/s), but it's far slower than modern NVMe SSDs. For Xbox Series X|S users, this means you won't get the full benefit of the console's Velocity Architecture when playing backward-compatible titles via USB. Competitors like the WD_BLACK P50 or
