Manufacturer description

The SSK 128GB USB flash drive behaves more like a small external SSD than a typical thumb drive. On a USB 3.2 Gen2 port it reaches up to 550MB/s read and 520MB/s write, so moving large video files, photo libraries or game installers takes far less waiting. SSK says the speed holds steady during long transfers instead of dropping partway through, though results will vary with your host device and port. The drive comes with a USB-C adapter, so one stick works with USB-A desktops, smart TVs and car stereos as well as USB-C smartphones, laptops and MacBook Pro/Air models. It also works in older…

Frequently Asked Questions

How fast is the SSK 128GB USB flash drive?

SSK rates it at up to 550MB/s read and 520MB/s write on a USB 3.2 Gen2 port. SSK says those figures come from its own internal testing, and real-world speed depends on your host device, port and usage.

Will it work with my iPhone or Android phone that has USB-C?

Yes. It comes with a USB-C adapter, so you can plug it into USB-C smartphones, USB-C laptops and MacBook Pro/Air models. Your phone still has to support external USB storage to read the drive.

Can I use it in an older USB 3.0 or USB 2.0 port?

Yes, it works in USB 3.0 and USB 2.0 ports. Transfers will be limited to what those ports can handle, so you only get close to 550MB/s on a USB 3.2 Gen2 port.

Is the drive waterproof?

SSK lists water and dust resistance, shock resistance and a zinc alloy shell, but it doesn't publish an IP rating. Treat it as splash-resistant rather than something you can submerge, and check the product listing for current protection details.

What devices besides computers can it connect to?

SSK lists compatibility with USB-A computers, smart TVs and car audio systems, plus USB-C smartphones, laptops and MacBooks through the included adapter. It is plug-and-play, so you don't need to install drivers.
