Through a Stephan Wiesner video I became aware of this super small ( ca. 11 x 5 x 1 cm ) and fast external solid state disk! Perfect and lightweight (100 g) backup disk for my photo trips. The Disk is available in 2 capacities, 500 GB and 1 TB, I have decided for the bigger one. Transfer rates up to 1050Mbps and a USB-C port make it perfect for my MacBookPro. For size comparison I once put a lens cap of a 24-120 mm Nikon lens next to it.
