Dual USB-C and USB-A 3.2 Gen 2 interface

This 128GB flash drive combines a USB-C connector and a USB-A 3.2 port in a single zinc-alloy body. It targets users who move files between modern phones, tablets and computers without carrying separate adapters or cables. The drive works straight from the box with no driver installation required.

128GB capacity with 550MB/s read and 520MB/s write

Rated sequential speeds reach 550MB/s read and 520MB/s write on a USB 3.2 Gen 2 host, dropping to 450MB/s on USB 3.0 or 3.1 Gen 1 ports. The EXFAT formatting lets Windows, macOS and Linux recognise the full volume, though Windows typically reports about 119GB usable space. Sustained transfers stay stable without the sharp mid-copy slowdown common on cheaper sticks.

Plug-and-play convenience across phones.

The dual-head design removes the need for OTG cables or cloud uploads when shifting photos, 4K video or project folders between an iPhone 15, Android handset, iPad, MacBook or Windows laptop. Zinc-alloy construction adds drop and abrasion resistance while helping dissipate heat during long writes. No bundled software or encryption utility is included; the drive relies on the host operating system for file management.

Questions about this item

Will the USB 3.2 Gen 2 interface still deliver full speed when I plug it into my older USB 3.0 ports?

When connected to USB 3.0 or USB 3.1 Gen 1 ports the transfer rate is limited to 450 MB/s instead of the 550 MB/s read and 520 MB/s write speeds available on USB 3.2 Gen 2.

How can I verify the drive is hitting its advertised 550 MB/s read and 520 MB/s write performance after setup?

Run a benchmark tool such as CrystalDiskMark on a USB 3.2 Gen 2 port; you should see sequential reads near 550 MB/s and writes near 520 MB/s if the drive and host controller are both functioning correctly.

Does the package include any adapters or cables, or do I need to buy a USB-C to USB-A adapter separately for older laptops?

The drive itself has both a USB-C and a USB-A 3.2 connector built in, so no extra adapter or cable is required for either port type.
