Review on SanDisk 256GB Ultra Dual Drive Luxe USB Type-C - High-Speed Data Transfer & Stylish Design by Jeffrey Gallagher

So far this drive has worked fine for me. It runs hotter than any other flash drive I've ever used. It's hot even when you're not using it; This is probably due to the large amount of memory. It's a metal and appears to be able to dissipate some heat. If you're using it with a laptop, it's likely to affect battery life. So you might want to turn it off when you're not using it.
