This article covers MOVE SPEED 256GB USBドライブ 2.

Overview

The MOVE SPEED 256GB USB Drive (model SP20) is a compact portable SSD that pushes the boundaries of what a thumb-drive-sized device can do. With a USB 3.2 Gen2x2 interface, it delivers read speeds up to 2,000MB/s and write speeds up to 1,800MB/s—rivaling many internal SATA SSDs. The drive uses TLC NAND flash for reliable sustained performance, even when transferring files larger than 100GB. Its dual-interface design (USB-A and USB-C) makes it compatible with a wide range of devices, from PCs and Macs to the latest iPhone 15 Pro and Android smartphones.
This 256GB model is priced around ¥12,888, offering exceptional value for users who need fast, portable storage without breaking the bank. It's small enough to hang on a keychain yet powerful enough to serve as a scratch disk for video editing or a game library drive. The market positioning is clear: an entry-to-mid-range portable SSD that punches well above its weight class in speed.

Compatibility Guide

  • Interface: USB 3.2 Gen2x2 (20Gbps) required for full speed. Backward compatible with USB 3.2 Gen2 (10Gbps), USB 3.0 (5Gbps), and USB 2.0 (480Mbps)—but speeds will be limited accordingly.
  • Operating Systems: Windows 10/11, macOS, iOS (iPhone 15 Pro and later), Android. Plug-and-play, no drivers needed.
  • Devices: Desktop PCs, laptops, MacBooks, iPhone 15 Pro/Pro Max, iPad Pro (USB-C), Android phones, game consoles (PS5, Xbox Series X/S as USB storage).
  • Important: Do not use through a docking station or USB hub—connect directly to the host device's USB port for best performance. Thunderbolt 5 ports work, but Thunderbolt 4/3 will negotiate at USB 3.2 Gen2x2 speeds.

Best Use Cases

  • Content Creators (video/photo): Ideal for transferring 4K raw footage or large photo libraries. The high sequential speeds make it suitable as a working drive for editing directly from the SSD. However, the 256GB capacity means you'll need to offload completed projects to larger storage.
  • iPhone 15 Pro Users: Connect via USB-C to offload ProRes video or back up photos. While the iPhone's USB-C port is limited to 10Gbps, the drive still offers fast transfers and frees up internal storage. Not ideal for users who need more than 256GB of mobile storage.
  • Gamers (PC/console): Use as a portable game library or backup drive. Works with PS5 and Xbox Series X/S as USB storage (for storing games, not playing PS5 games directly). Great for moving game installations between PCs.
  • Laptop/Ultrabook Users: A compact companion for expanding limited internal storage. Perfect for carrying work files, presentations, or a portable OS installation.

Things to Consider

  • Full speed requires compatible hardware: To achieve 2,000MB/s read, your PC must have a USB 3.2 Gen2x2 port. Most current laptops and desktops only support USB 3.2 Gen2 (10Gbps), which will cap speeds at around 1,000MB/s. Check your device's specifications before purchasing.
  • Capacity reality: 256GB formatted is about 238GB, with usable space around 232–238GB. This is normal for all storage devices, but be aware if you plan to store large files.
  • Avoid docking stations: The manufacturer explicitly warns against using docking stations or hubs, as they can cause speed degradation or connection issues. Always connect directly to the host device.
  • Competition: Alternatives like Samsung T7 or SanDisk Extreme Portable offer similar build quality but lower speeds (around 1,050MB/s). The MOVE SPEED drive is faster on paper, but real-world performance depends on your system's USB controller and cable quality.
  • Heat: The drive can get warm during sustained writes. Thermal throttling may occur during very long transfers, reducing speed temporarily.

FAQ

Q: Can I use this drive with my iPhone 15 Pro? What speed will I get?
A: Yes, the iPhone 15 Pro's USB-C port supports USB 3.2 Gen2 (10Gbps), so you'll get up to about 1,000MB/s transfer speeds—still very fast for ProRes video offloading or photo backups.
Q: Can I play PS5 games directly from this drive?
A: No, PS5 games cannot be played directly from an external USB drive. You can store PS5 games on it and transfer them to the internal SSD when you want to play.
