• The Lexar Muse SSD gets as thin as 1mm (0.04 inches)
• It comes with a proprietary connection mechanism
• 512GB and 1TB storage models of the drive will be available

Every year at the IFA tech expo, there are claims of gadgets being lighter, thinner, faster, and smarter than ever before — but amid the usual crop of claims we've seen in 2026, the Lexar Muse particularly stands out.

This is officially the thinnest portable SSD on the market, measuring a mere 1mm (0.04 inches) at its thinnest points around the edges, and a not-exactly-chunky 3.8mm (0.15 inches) at its thickest point in the middle.

It's not unlike a credit card in terms of its looks and dimensions, and Lexar seems particularly keen to promote the idea of it being used strapped to the back of a MagSafe iPhone to provide some additional storage space on the go.

The unibody metal enclosure around the drive has been formed from a single piece of metal to minimize gaps and seams, while some space saving has gone on inside with custom PCB architecture and high-density NAND stacking.

What's a little unusual here is the connectivity, which has to happen via the magnetic pogo-in connector on the back of the drive — there's no traditional USB-C port that you can plug an existing cable into.

You do get a bespoke cable included with the drive, as well as a carry case for easily attaching the drive to the back of something like an iPhone. However, the magnetic connection might not be the most robust.

The Lexar Muse offers some respectable read and write speeds of up to 1,050MB/s and 1,000MB/s respectively (so good enough for 4K 120fps Pro Res video on an iPhone), and there are going to be 512GB and 1TB models available.

As is often the case at IFA, there's no word on pricing yet, but you can expect the Lexar Muse to hit shelves before the end of the year. If you prioritize thinness and lightness over everything else, it may be worth checking out.
