Give it up for the Biwin CL100. It looks like a phone SIM card, and it's not the first time we've seen it, but now we have more details. It packs up to 2 TB of proper NVMe storage and runs at up to 3.7 GB/s (via Videocardz). It's not even that outrageously expensive, for now. There is, however, a catch. It's a proprietary rather than open standard.
What really marks this drive out from, say, the even smaller microSD format is the combination of performance and full NVMe 1.4 support. The CL100 measures 15 mm by 17 mm and fits into a slide-in tray that very much resembles a phone SIM tray.
