This article covers G-Technology SSD 外付 ポータブル 2TB G-DRIVE Mobile SSD R-Series USB3.1 Gen2 5年保証 0G06054.

Overview

The G-Technology G-DRIVE Mobile SSD R-Series 2TB is a rugged external portable SSD designed for demanding field use. It offers sequential read speeds up to 560MB/s over USB 3.1 Gen 2, and features IP67 water and dust resistance, 3-meter drop protection, and 1000-pound crush resistance. With 2TB of capacity, it's an ideal companion for creative professionals and field workers who need to carry large amounts of data safely.
Measuring just 50×95×14.6mm and weighing only 86g, this drive is incredibly compact and lightweight. The aluminum enclosure provides excellent heat dissipation, ensuring stable performance during extended use. Included USB-C and USB-A cables ensure broad compatibility with modern laptops and older PCs alike.
Positioned in the mid-to-high tier of portable SSDs, the G-DRIVE Mobile SSD R-Series stands out for its exceptional durability. It comes with a 5-year warranty, offering long-term peace of mind for users who rely on their data in challenging environments.

Compatibility Guide

The G-DRIVE Mobile SSD R-Series uses a USB 3.1 Gen 2 (USB-C) interface. It connects directly to any USB-C port on modern laptops and desktops. The included USB-A adapter allows use with older USB-A ports. It is bus-powered, so no external power adapter is needed.
Supported operating systems include macOS 10.10 or later and Windows 10, 8.1. Note that the drive comes formatted for macOS (HFS+); Windows users will need to reformat it (exFAT or NTFS) before use. For cross-platform use, exFAT is recommended.
The drive is a 2.5-inch form factor external unit, not intended for internal installation. Since it draws power from the USB port, be mindful of battery drain on laptops.

Product Info

Released around 2018, this model remains a popular choice for rugged storage. The 2TB variant typically retails for around ¥20,000 (as of September 2026). It comes with a 5-year manufacturer warranty.
G-Technology is a brand under Western Digital, known for reliable storage solutions. The G-DRIVE Mobile SSD R-Series is positioned as a mid-to-high tier product, with its IP67 rating and drop resistance as key differentiators from standard portable SSDs. Transfer speeds top out at 560MB/s, which is practical for USB 3.1 Gen 2 but not the fastest available.

Best Use Cases

  • Field photographers and videographers: The IP67 rating and drop protection make it ideal for outdoor shoots in rain or dusty conditions. 2TB capacity handles 4K footage and RAW photo backups. However, if you need faster transfer speeds for large file workflows, consider a Thunderbolt 3/4 SSD.
  • Frequent business travelers: At 86g, it slips into a pocket easily. Perfect for carrying presentations, documents, and backups securely. But if you transfer massive datasets daily, a higher-speed NVMe external SSD might be more efficient.
  • Outdoor enthusiasts and travelers: Great for backing up photos and videos on trips where gear might get bumped or wet. For home/office use only, a cheaper standard portable SSD would suffice.

Things to Consider

The main trade-off is price: the rugged construction commands a premium over standard portable SSDs. If you don't need IP67 or drop resistance, you can save money with a less rugged model.
Transfer speed maxes out at 560MB/s, which is slower than modern NVMe external SSDs that can exceed 1000MB/s. For frequent large file transfers, this may be a bottleneck.
Windows users must reformat the drive before use, which is an extra step. Also, the drive lacks hardware encryption, so software encryption is needed for sensitive data.

FAQ

Q: Can I use this SSD with a PS5 or Xbox Series X?
A: It works as external storage for both consoles. On PS5, you can store and play PS4 games, but PS5 games cannot be played directly from it (requires internal or M.2 SSD). On Xbox Series X/S, you can store and play backward-compatible games, but optimized titles require internal storage.
Q: Why is my transfer speed slower than advertised?
A: Ensure you're using a USB 3.1 Gen 2 port and cable. Older USB 3.0 ports will limit speed to around 400MB/s. Also, background tasks or other USB devices can reduce throughput.
Q: Does this drive support hardware encryption?
A: No, it does not have built-in hardware encryption. You can use software encryption like BitLocker (Windows) or FileVault (macOS) to protect data. The IP67 rating protects against physical damage, not data security.
