Overview
Samsung built this 256GB drive around a reversible USB-C plug rated up to 400MB/s under USB 3.2 Gen 1, with backward compatibility down to USB 3.0 and 2.0. It's aimed at moving large files between phones, tablets and computers that already use Type-C.
Samsung positions the housing as rated against water, shock, magnets, temperature and X-ray exposure, which matters more for a drive that lives in a pocket or bag than one left plugged into a desktop. Being reversible removes the fumbling a rectangular USB-A plug involves, though it also means the drive is far less useful on older laptops without a USB-C port unless paired with an adapter. Samsung backs it with a 5-year limited warranty.

Who it's for
People who shuttle large files, like 4K video or big photo batches, between USB-C phones, tablets and laptops are the target buyer. Anyone whose devices are all still USB-A only will find the reversible plug pointless without an adapter.

Performance notes
The drive uses Samsung NAND flash and is rated up to 400MB/s under USB 3.2 Gen 1, with backward compatibility down to USB 3.0 and 2.0 speeds when plugged into an older port. Samsung lists the housing as waterproof, shockproof, magnet-proof, temperature-proof and X-ray-proof, aimed at surviving a bag or pocket rather than a desk. At 256GB, Samsung estimates room for around 63,730 photos or up to 12 hours of 4K video.
