I took a flash drive to replace the old slow one and not very big. I use it through an adapter to Type-C. I was very pleased with the speed - the files fly in quickly, and are downloaded instantly. For a 2.2 GB file, my speed was: 60 MB / s when transferring to a USB flash drive and 360 MB / s when transferring a file from a USB flash drive.
