Compatibility Guide

The drive uses a USB 3.2 Gen 2x1 interface and works with any device that has a USB Type-C or Type-A port. It is compatible with Windows, macOS, Linux, and Chrome OS out of the box. For maximum speed, connect to a USB 3.2 Gen 2x1 port. Backward compatible with USB 3.0 and 2.0 ports, though speeds will be limited. Dual connector design covers both modern USB-C laptops and traditional USB-A desktops. * No driver installation or formatting required; the drive is recognized as an external storage device.

Product Info

Released in 2024, the Integral USSD 256GB SlimXpress Dual is priced competitively in the ¥2,500–¥3,500 range, offering excellent value for a 256GB portable SSD. The manufacturer provides a 2-year warranty. It sits in the entry-level market segment but stands out with its USB 3.2 Gen 2x1 support, offering read speeds roughly 5x faster and write speeds about 10x faster than typical USB 3.0 flash drives. This makes everyday file transfers noticeably quicker. Interface: USB 3.2 Gen 2x1 (up to 10Gbps) Read speed: up to 550MB/s Write speed: up to 500MB/s Capacity: 256GB Form factor: USB stick Material: Dual metal construction * OS support: Windows, macOS, Linux, Chrome OS

Best Use Cases

Mobile workers and students: Perfect for sharing files between a laptop and tablet. The dual Type-C/Type-A support eliminates the need for adapters. Photographers and videographers: Quickly transfer large RAW images or 4K video files. The high sequential speeds reduce waiting time during backups or data migration. * Secondary storage: Ideal for users who need extra space on their main PC without opening the case. The compact size keeps the desk clutter-free.

Things to Consider

This is a USB flash drive form-factor portable SSD, not an internal NVMe drive. Random read/write performance is lower, so it is not recommended as a boot drive or for running applications directly. The 256GB capacity is sufficient for everyday files, but heavy media users may want to consider 512GB or 1TB alternatives. Competitors like SanDisk and Samsung offer similar portable SSDs with potentially higher sustained write speeds and better endurance (TBW). However, the Integral SlimXpress Dual is generally more affordable. Its cable-free design is convenient but increases the risk of losing the drive. Regular backups are advised.
