Lexar Muse Sacrifices USB-C Port for Thinness, Skips Thermal Testing

Lexar just announced the Muse, a portable SSD so thin it tapers to 1mm at the edges — competing for slimmest drive on the market by sacrificing a full-size USB-C port.

You get USB-C, technically, just a reduced one that needs an adapter for most cables. The announcement treats this as inevitable progress, the inevitable tax of thinness.

This mirrors the MacBook Air in 2008. When Steve Jobs unveiled it — a laptop under four pounds, thin enough to fit inside a manila envelope. The achievement was legitimate. The thermal design couldn't handle sustained workloads and it throttled under heavy use. Reviewers celebrated the form factor without benchmarking real-world performance because everyone still measured laptops on paper, in controlled conditions, not where actual people used them.

For five years, "thin" became synonymous with "premium" in laptop design. By the time thermal limitations appeared in reviews, the design language had already metastasized across the entire industry and thinness became the spec that mattered most, with thermal limits an acceptable cost. Here's what's different with the Muse. You can buy it today and write a real benchmark with sustained writes over an hour, thermal imaging. Whether the adapter cable is actually usable.

The information isn't hidden, just untested.

The information isn't hidden, just untested. Everyone writing about the Muse right now has the tools to check whether slimness is compensating for something you'll notice, or whether it's pure theater. The question is whether they'll bother, or whether we're trained now to accept that form factor is what we measure and everything else resolves itself later.
