This article covers KEXIN 256GB 外付けSSDハードドライブ USB 3.1 Type-c ポータブルソリッドステートドライブ 256G 最大500MB.

Overview

The KEXIN 256GB external SSD is a compact portable drive featuring a USB 3.1 Type-C interface with read/write speeds up to 500MB/s. Its aluminum housing provides impact resistance and heat dissipation, making it suitable for daily data transport. This entry-level SSD offers a cost-effective solution for users who need extra storage without breaking the bank.
Compatible with a wide range of devices including laptops, desktops, PS4, Xbox, Android smartphones, and tablets, the drive comes with both a USB-C to USB-A cable and a USB-A to USB-C adapter. This ensures seamless connectivity with older and newer hardware alike. The plug-and-play design requires no additional drivers, simplifying setup for non-technical users.

Compatibility Guide

The KEXIN 256GB external SSD connects directly to any device with a USB 3.1 Type-C port. Using the included adapter, it also works with standard USB-A ports found on older PCs and game consoles. Supported operating systems include Windows, macOS, Android, and Linux.
For gaming consoles, the drive can be formatted as external storage on PS4, PS4 Pro, Xbox One, and Xbox Series X|S. Note that PS5 only supports PS4 game storage and playback via USB; native PS5 games cannot run directly from this drive. Android devices with OTG support can access the drive for file management.

Product Info

Released around 2024, the KEXIN 256GB external SSD is available through online retailers and other online retailers. Pricing hovers around ¥14,000 (as of September 2026), positioning it as a budget-friendly portable storage option. Warranty is typically one year, though exact terms vary by seller.
Market positioning is entry-level. While not as fast as NVMe-based external SSDs, it delivers adequate performance for everyday file backups, media storage, and light gaming. The aluminum construction and compact dimensions (85.9×41×10mm, 52g) make it highly portable.

Best Use Cases

  • Data Backup: Ideal for users who need to regularly back up important files from a laptop. The small size and light weight make it easy to carry, and USB connectivity ensures broad compatibility. Suitable for those who prefer local storage over cloud services.
  • Console Storage Expansion: Gamers running out of space on PS4 or Xbox internal drives. Using the SSD as external storage can reduce game load times compared to HDDs. Not recommended for PS5 native games.
  • Mobile File Management: Android users who frequently transfer photos and videos between devices. Direct USB-C connection and OTG support allow easy file access via file manager apps. iPhone users will need a Lightning adapter.

Things to Consider

The advertised 500MB/s speed is the theoretical maximum for USB 3.1 Gen1; real-world performance depends on the host device's USB controller and file size. Creative professionals working with large 4K video files should consider faster NVMe external SSDs (1000MB/s+).
At 256GB, the capacity is sufficient for OS backups and photo libraries but may fall short for storing multiple modern AAA game titles. Users needing more space should look at 512GB or 1TB variants, though at a higher cost.
The manufacturer does not publicly specify TBW (Total Bytes Written) ratings, making this drive less suitable for write-intensive workloads like server caching. For read-dominant daily use, however, it performs reliably.

FAQ

Q: Can this SSD be used with PS5?
A: Yes, as external storage for PS4 games and data transfer, but PS5 native games cannot be played directly from it. It works as a USB extended storage drive for PS5.
Q: Why is the actual transfer speed slower than advertised?
A: The 500MB/s rating is based on USB 3.1 Gen1 theoretical bandwidth. Actual speed is affected by the host controller, file fragmentation, cable quality, and whether the port is USB 2.0 (which caps at ~40MB/s).
Q: What is included in the package?
A: The package contains the SSD, a silicone shell, USB-C to USB-A cable, USB-A to USB-C adapter, a carrying pouch, and a user manual (which may not be in Japanese).
