SDDDC4-256G-G46

High-performance USB Flash drive of considerable capacity (256 GB) with an original design that includes two popular USB 3.2 Gen1 interface connectors at once: traditional Type-A and more modern reversible Type-C. To use one of these connectors, you just need to turn in the right direction the movable part of the case, equipped with an eyelet for attaching a cord. With this versatility, the SanDisk Ultra Dual Drive Luxe USB Type-C 256GB can be easily connected to any personal computer, laptop or Ultrabook, including the latest Apple MacBooks.

It is also possible to directly connect to tablets / smartphones that are equipped with a Type-C connector and support the OTG function. High-quality flash memory and a modern controller allow the drive to develop high sequential read / write speeds (up to 150/60 MB / s) for quickly moving files between a PC, tablet, smartphone and laptop without cloud services and network connections. This gives complete privacy, which is important for sensitive personal and business-oriented data. Copying a 3 GB video file from such a device to a computer / laptop takes less than half a minute, and transferring hundreds of photos will take only a few seconds. The small overall dimensions of the metal case and modest weight allow you to carry the drive in any pocket.

Model overview based on user reviews  
The SanDisk Ultra Dual Drive Luxe USB Type-C is a versatile USB flash drive available in various capacities, ranging from 32GB to 1024GB. It features a sleek silver design and dual connectors, making it convenient for both USB Type-C and USB 3.2 gen1 devices. Users appreciate its compact size and the support for OTG functionality. However, a significant concern is that the drive heats up considerably during data transfer, which can lead to a drastic drop in write speed, especially noted in the 512GB model. This overheating issue makes it uncomfortable to handle and can result in lengthy transfer times for large files. While some users find it to be a wonderful model, others caution against purchasing due to these performance drawbacks.

do not recommend to buy
OTG, dimensions, design
When writing data, this USB drive (I have the 512 Gb model) heats up critically and the write speed drops catastrophically. Because of this, a file several Gb in size can take several hours to write (transfer to the flash drive).
