Manufacturer description

The SSK 256GB Portable SSD is a pocket-size external solid state drive for moving files between your phone, laptop and console. It comes with a 2-in-1 cable that has both a USB-C and a USB-A connector, so the same drive plugs into an OTG-enabled Android phone, an iPhone 15, an iPad, a MacBook, a Windows PC or an Xbox without an adapter. SSK rates the drive at up to 550MB/s read and 500MB/s write over USB 3.2 Gen2, which it says is about 10 times faster than a USB 2.0 flash drive. That makes it easy to offload high-resolution photos and video from your phone or carry large project folders…
