This article covers SanDisk 外付SSD 2TB エクストリーム ポータブル 読出し速度 最大550MB.

Overview

The SanDisk Extreme Portable SSD 2TB (model SDSSDE60-2T00-G25) is an external solid-state drive that connects via USB 3.1 Gen2, offering read speeds up to 550 MB/s. Its compact 2.5-inch form factor and dust-resistant design make it suitable for on-the-go use, whether you're backing up photos, storing game libraries, or transporting large project files. Positioned as an entry-to-mid-range portable drive, it delivers reliable SATA SSD performance in a rugged, pocket-sized package. A data recovery software bundle is included, adding peace of mind against accidental file loss. Because it's bus-powered, you don't need a separate power adapter—just plug it into any USB port on your laptop or desktop. The 2TB capacity provides plenty of space for large media collections or multiple system backups.

Compatibility Guide

This drive uses USB 3.1 Gen2 (also known as USB 3.1 10Gbps, though the interface is actually SATA inside so max speed is 550 MB/s). It is backward compatible with USB 3.0 and USB 2.0. For optimal transfer speeds, connect it to a USB 3.1 Gen2 or USB 3.2 Gen2 port. It works with Windows, macOS, and most Linux distributions without additional drivers. No internal mounting is needed—just connect via the included USB cable.

Product Info

Launched around 2018, the Extreme Portable SSD is widely available through retailers and import channels. Pricing for the 2TB model hovers around ¥113,000 on Japan. Official warranty is 3 years for genuine units, but parallel imports may have limited coverage. Market position: entry-to-mid tier, offering SATA-level performance in a portable, durable enclosure. It is dust-resistant and designed to withstand minor bumps and shocks.

Best Use Cases

For photographers and videographers: The 550 MB/s read speed handles large RAW images and 4K video files efficiently. The dust-resistant build helps when shooting outdoors. However, for direct editing off the drive (constant read/write), an internal NVMe SSD is faster. This drive is best for transferring and archiving finished projects. For students and professionals: Ideal for carrying coursework, presentation files, or work documents between home and office. Bus power means you can use it in a coffee shop without hunting for an outlet. If you rarely move large amounts of data, a cheaper HDD might suffice. For gamers: Works well for storing game installers or moving games between PCs. Compatible with PlayStation 4 and Xbox One for game storage. On PS5 or Xbox Series X|S, it can store and play backward-compatible titles, but native games require the internal SSD or an expansion card.

Things to Consider

The drive's write speed is not specified and is typically lower than the read speed—don't expect symmetric performance. As a parallel import, you may lack local language manuals and official support. If you need water resistance or higher ingress protection, consider an IP-rated model. For users with a USB 2.0-only PC, speed will be severely bottlenecked (under 40 MB/s). Also, the included cable is short; a longer quality USB cable may reduce performance. ## FAQ
Q: Can I use this SSD with my PS5? A: Yes, via USB. The PS5 will recognize it as external storage for PS4 games and media. You cannot install or play PS5-native games from it. Q: Does it work with Mac and PC out of the box? A: It comes formatted as NTFS (Windows). On Mac it will mount read-only unless you reformat to exFAT. Reformatting erases all data. Q: How durable is the dust resistance? A: The product is described as dust-resistant (not IP-rated). It can handle light dust and debris but is not sealed against submersion or heavy particles.
