The SanDisk Professional PRO-BLADE is an NVMe-based SSD system designed for M&E professionals to facilitate the easy transfer of data between different people. The system is based on a separate reader and media, which SanDisk calls a “Mag” (which, probably intentionally, is also the industry jargon for camera media). The single-mag reader called the TRANSPORT, leverages USB-C 3.2 Gen 2x2, or in normal people's terms, USB 20Gb/s. It’s also bus-powered, which is a nice plus.
