This article covers SANDISK (サンディスク) 1TB エクストリーム ポータブル SSD (旧モデル).

Overview

The SanDisk Extreme Portable SSD 1TB (model SDSSDE61-1T00-G25M) is a rugged external NVMe SSD from Western Digital's SanDisk brand. It delivers sequential read speeds up to 1050MB/s and write speeds up to 1000MB/s over USB 3.2 Gen 2, making it a solid choice for on-the-go data transfers. With IP65 water and dust resistance and 3-meter drop protection, this drive is built for tough environments. It also features 256-bit AES hardware encryption for added security. Compatible with PCs, Macs, consoles, and mobile devices, it offers broad versatility.

Compatibility Guide

The drive uses a USB Type-C interface and requires a USB 3.2 Gen 2 port for full speed. It works with USB 3.0/2.0 ports at reduced speeds. An included USB-C cable and USB-A adapter ensure broad compatibility. Supported devices include Windows, macOS, iPad Pro, Android, PlayStation 5, and Xbox Series X|S. For console use, format the drive to exFAT for best compatibility.

Product Info

Released around 2023, the 1TB model typically retails for around ¥37,000 (as of August 2026). SanDisk offers a 5-year limited warranty. Positioned as a mid-range portable SSD, it balances high-speed NVMe performance with rugged durability. The IP65 rating means it's protected against low-pressure water jets and dust ingress, suitable for outdoor and job-site use.

Best Use Cases

Creative professionals: Ideal for transferring large RAW photo libraries or 4K video footage in the field. The rugged build withstands drops and weather. Gamers: Useful as external storage for PS5 or Xbox Series X|S for backing up games or storing PS4 titles. Not suitable for playing PS5 games directly. Business users: AES encryption keeps sensitive data secure during travel. The carabiner loop allows easy attachment to bags. Outdoor enthusiasts: Perfect for camping or hiking trips where you need to offload photos from cameras or drones. IP65 and drop protection provide peace of mind.

Things to Consider

This is the "old model" — the newer Extreme Portable SSD V2 offers up to 2000MB/s and IP68 rating. If you need maximum speed or full waterproofing, consider the V2. However, the old model is still very capable for most users and often costs less. Note that IP65 does not mean submersible; avoid prolonged water exposure. Also, the drive does not support USB 3.2 Gen 2×2 (20Gbps), so it won't benefit from the fastest USB ports. ## FAQ
Q: Can I use this SSD with my PS5 to play PS5 games? A: No, PS5 games cannot be played from an external USB drive. You can store and play PS4 games, and use it for backing up PS5 game data. Q: Does it work with iPhone? A: Direct connection to Lightning iPhones requires a Lightning-to-USB adapter. For iPad Pro with USB-C, it works natively. Q: What's the difference between this and the newer model? A: The newer V2 model doubles the speed to 2000MB/s and has IP68 (full dust and water immersion). The old model is IP65 (water jets only) and 1050MB/s. Price difference is usually ¥3,000–5,000.
